Nathan Scott is Tree Hill High's biggest basketball star and is dating Peyton, a cheerleader. Nathan's half brother, Lucas, joins the team - and threatens to take both Nathan's spot in the lineup and his girl.

Lucas plays his first game as a Tree Hill Raven...and chokes. He isn't the only one confronting insecurities: Peyton can't find the courage to submit her drawings for publication.

Frustrated by Lucas' growing popularity at school, Nathan searches for Lucas' weak spot, and has the team begin to initiate hazing incidents against him. Nathan also tries to seek tutoring help from Haley. Brooke begins to fall for Lucas. Meanwhile, Peyton is furious with Lucas for submitting her drawings to the local newspaper without her knowledge.

After Lucas crowns another good game with the winning point, Nathan switches to plan B, inviting him to a party at his dad's luxurious beach house where he cleverly humiliates him with a truth game and a video of Lucas ma calling Dan her dream husband. After Lucas walks out livid, Haley is stranded, accepts a ride back from Nathan in Peyton's car and accepts to keep tutoring him since failing grades would kill all his and Dan's dreams. On his way back Nathan crashes into Lucas in the car of one of Keith's clients; Nathan thinks he can bluff his way out making Tim his false witness, but there are nasty consequences for both brothers, their girls friends and their parents.

After the disastrous party and car crash, things still look bad for everyone. Peyton meets coach at the cemetery and exchanges grief and memories about her mother's death in a car accident the one time she ignored a red light and his late wife Camilla. With the benefit match between the Ravens boys and their fathers coming up, captained by Nathan and Dan Scott, Keith is honored to be asked as substitute by his nephew Lucas, and joins in with his mother asking him to reconsider his intent to change his last name to hers after Dan barged in at Keith's auto shop saying Lucas is unworthy of the name. At the game, Dan is the only father who can't just enjoy being creamed by their heirs- he even barges in with the boys after their glorious first half, barking so badly Keith has to defend even Nathan. Dan's behavior on the court is no more sportsmanlike, even at Nathan's expense- the golden boy's filial loyalty gets shocked in both senses of that verb.

Things are so bad between the Scott half-brothers that they are thrown off the court for rolling over the floor fighting each-other during a game in a North Carolina hick-town, Pinkerton. Brooke is hurt and scams a strong painkiller from a med student, but takes an overdose which forces Haley and Peyton to give the 'drunk' a ride; despite car trouble, they'll have it relatively easy getting back home. Coach decides to punish Nathan and Lucas by making them walk some 30 miles, which turns out just the 'fraternal' male bonding they needed as they are not given a lift but abducted by local hicks who force them to go shopping in their undershorts marked 'Ravens suck' on their backs; even after doing so, their ordeal is far from over... On the home front, Dan and Keith seize the evening without the boys to take Nathan's mother, Deb and Lucas's mother, Karen out, but land in the same restaurant where they get into a fight of their own.

The night of Dan and Deb's annual basketball appreciation party stirs up old wounds and new feelings as Karen makes a new friend, Keith faces off with his younger brother once again and Lucas finally makes his move on Peyton. Also, Haley and Nathan grow closer until Brooke spreads a vicious rumor that leaves Haley devastated.

Brooke takes Peyton to a college party but the night takes a bad turn when someone drugs Peyton's drink. Nathan and Haley go on a scavenger hunt date set up by Brooke in an attempt to make up for her actions at the party the night before.

Tension mounts now the Ravens may get their first ever undefeated season if they win against Cove City, but instead of encouraging his son, Dan barks at Nathan he doesn't go deep enough while ordering him to convince his mother he's not unhappy, thus blaming the poor kid for her punishing him by running Karen's place. He decides to take amphetamines supplied by Tim's brother, which make him so aggressive coach throws him out at training; when he gently tries to take the next step while kissing Haley, she also shows him the door. Brooke gets Lucas to go out as 'reward' for recommending a book she lobes, then makes him drink and- get a real tattoo, to Keith's in loco parentis despair and fury. At the crucial game, Nathan's second pill dose lands him first on the bench and next in hospital. Dan doesn't believe the doctors correct substance diagnosis; he didn't even call Deb, who tells him to leave home for good.

After Peyton walked in on Lucas kissing Brooke the night she got him drunk, they all feel uncomfortable but decide to stay friends; Haley and Peyton even team up to organize live entertainment in Karen's café. Because of Nathan's pills-disaster, coach cancels basketball practice till further notice, telling livid Dan -who fears for the Ravens' shot at a perfect season- 'the game is no fun any more' so he takes off pressure. Nathan feels happy again taking things easy with Haley, but Dan decrees they're 'going to have a good time' on the golf weekend he planned with Deb till she threw him out, leaving the boy no escape from worrying about his parents plausible divorce in between humiliating golf 'lessons' in his dad's arrogant style, till he walks off shouting nobody can be happy with a bully like Dan. Jake shows Lucas why coach cuts him slack: his 6 months old baby Jenny, abandoned by her mother, and gets the advice not to keep that secret any longer. Jake uses the 'open mike' at Karen's to out his baby; afterward Lucas invites Nathan to the Rivercourt where all the kids enjoy informal basketball, putting coach and Keith's worries to rest.

After Deb drags Dan and Nathan to a family therapist, where they only fight and each expect Nathan to take their side, Nathan looses faith in everything except Haley. Brooke begins to feel jealous about Lucas, but insecure as they have almost no common interests; Lucas and Peyton both reassure her. Lucas finds Peyton's dad home for once; he tells her another, even better paid job will drag him for months to New Zealand... Nathan talks to Keith and coach, who both tell him to do what's best for him, even if that means dropping basketball; he cuts practice and classes, even takes Haley with him playing hooky, to Dan's disgust in more then one way...

On Dan's birthday, his parents turn up unannounced; Dan tries to make everybody keep Nathan's quitting from them, and Haley offers to come for moral support. Just when she was counting off her dad's return home, Peyton gets a call a storm knocked four men off his ship, and she must identify if a corps is his, so Lucas drives her, but the roads are blocked too so they must spend the night in a motel, but Lucas doesn't forget Brooke. At the Scott diner, the mothers tell the truth, how grandpa Royal Scott also pushed Dan too hard till he took his mother's advice to use a knee injury to quit basketball altogether; like coach Nathan walks out disgusted, losing all respect for the man he always tried desperately to please, and decides how to deal with it.

In therapy with Deb, who by now wants a divorce, Dan tells he cut Lucas out of his life like a trapped man amputates his arm to survive. Haley gets basketball lessons (to pass PE) from patient Nathan, who to everyone's relief is back with the Ravens. Coach tells Keith he promised his wife 35 years ago they would 'start living' after 20 years of coaching; he just won 500 matches, but what about his most important intention: to make a difference? Strolling on the beach Dan meets Carrie, who fails to seduce him when invited to eat his spare steak as Nathan declined, but just then Deb walks in. Now Brooke believes Lucas is her first true love, he and Peyton don't come clean about the motel; but Haley overhears them and has a row with him. Nathan convinces coach he does matter for boys like him who still need guidance. While driving with Lucas, Keith is hit by another car. Dan is nearby and rushes Lucas to the hospital.

When the doctor tells Keith it's too soon to tell how bad Lucas's injuries are, he informs Haley, who throws Nathan out immediately and calls Peyton, who is with Brooke at the time. A surprised Karen learns Dan saved Lucas by bringing him in and giving permission for surgery as his father, while Keith caused the accident under nearly illegal influence of alcohol. Karen and Deb comfort each-other at Lucas's sickbed, where Peyton briefly and Brooke more elaborately meet Karen. After Haley gives him the silent treatment, Nathan sadly admits to Deb he barely minds she's separating from Dan. Karen hears her insurance probably won't cover all the hospital bills, and finds out later that Keith paid the bill. Coach assures Karen not to doubt Keith's love for Lucas. Jake and the park court basketball gang make a get-better-video for Lucas; even Tim joins in making a chalk drawing on the court. Dan cancels marriage mediation, and isn't impressed by Deb's lawyer either, but gets a hug from Karen. Peyton tells Haley Lucas reads her soul. Nathan says at Lucas's sickbed he envies him sometimes and suggests he make up with his loved ones. Lucas wakes up with Nathan on his bedside. Nathan goes to get Haley, telling her he doesn't regret having courted her for the wrong reasons as she changed him for the better, then gives her a ride to hospital.

Now Lucas is out of the coma and released home, where his ma tries to make him take it easy on doctors orders, Jake brings him a games console as a get-better-and-return gift from the Ravens and uses the opportunity to get a job in Karen's café. Nathan tells his ma he understands his parents' divorce is the only option by now, and turns all his attention to Haley, who makes him realize he's not a baby who must go where he's told but can legally choose; both parents seem confident and determined to win him over, but Dan convinces him Deb doesn't stand a chance because of her secret past. Lucas has decided to break up with Brooke -but didn't tell her- sneaks out to Peyton and collapses there; he is rushed to the emergency room, Brooke finds out and faces Peyton bitterly. Although Karen is determined to repay Keith Lucas' medical bills, since Keith 'can't repay' having endangered his life, he cashes in all his savings and plans a mortgage on his garage.

Nathan must choose which parent to live with after Dan and Deb's divorce. Dan forces Nathan to make the decision by threatening to reveal Deb's darkest secrets in court unless Nathan chooses him. Meanwhile, Lucas meets a beautiful stranger who challenges his perceptions of life since Lucas' car accident.

Nathan has moved into his own apartment, away from both parents. To prepare for a match away, Coach orders Lucas to coach Nathan's weakest points, and makes them uneasy roommates; in the evening the boys sneak out but the strip joint Tim 'could get them in' turns out to be queer. Peyton and Sparkle Classic cheer-leading coach Brooke also find themselves bunking together; when Theresa falls sick, Haley is recruited and gets a crash course. Mouth spies the other teams -he demonstrates with more talent then most girls!- so they rework both choreography (Brooke) and music (Peyton); after training Brooke gets the hot pool opened, the boys jump in and coach grills chaperons Karen and Peyton's dad Larry Sawyer, but nobody minds. The new routine rocks, so Brooke wins the choreography prize. In the game Nathan uses the fade-away Lucas proposed and scores the winning point. At the home front manager Keith feels smothered by Dan and his men, and makes a drastic choice.

Lucas, Nathan and Jake are auctioned off to the highest bidder in the annual "Boy Toy" charity auction and the night leads to surprising developments with old flames. Meanwhile, having missed out on the auction, Brooke ends up with Mouth and gives him the night of his life.

Lucas believed he saw more then an auction slave's duty when Nathan kissed Peyton, but confronted Nathan is convincingly indignant. Brooke and a test kit tell Lucas they're expecting a baby. Jake still refuses Nikki any part in Jenny's life. Nathan tells Haley he doesn't understand she won't share his bed but tattooed his jersey number on her backside. After 15 years Keith proposes to Karen, who 'isn't ready', and decides to leave. Dan tells Lucas not to let Brooke ruin his life as Karen did by having him; and bursts in at Nathan's to tell him the beach-house will be waiting 'when' he hits rock bottom.

Keith has a solicitation as auto-shop teacher in a Charleston school; Lucas is heartbroken his surrogate father may move that far away. Haley and Nathan finally feel cozy living together, but when Dan finds out he sold the car he gave his poor son, he demands the money it fetched unless he moves in with him again- so the kid chooses to stay poor and takes a lousy job serving food in the mall, where a kid he never even noticed in his history class is now the sports heroes' vindictive boss- one visit by Dan convinces even him to go easy on the long-envied golden boy whose silver spoon came at such a price, so he won't miss his own housewarming party. When he gets there, Mouths music and Nikki literally fighting with Peyton have alerted the police, so Dan -who just got in bed with Deb- gets a call from the sheriff to bail him out.

The knowledge that Dan actually requested joint custody over Lucas but was turned away by Karen makes Keith doubt her and the Scott boys, who now train together as friends, how their lives would have been growing up as brothers. Peyton and Brooke lose Jake's baby daughter Jenny in the mall, and find Nikki picked her up. Haley is furious when she finds porn sites on Nathans computer, even though everybody else considers cyber-sex innocent fun, no competition for her. Since coach Whitey must have an operation, Dan manages -to his fury- to be made Ravens coach for one match, and works the boys like a penal company. Jake thinks he'll lose a custody battle against Nikki, so he considers moving to family in Savannah and gets Peytons support. Lucas comes to a decision which worries both Karen and Keith.

Lucas and Nathan bear the brunt of Dan's abuse as he coaches them into the playoffs, pushing both of them to their breaking points. Haley is stunned after Dan threatens her, causing her to reconsider her relationship with Nathan. Meanwhile, Whitey learns that his medical condition may be more serious than he first expected, and Dan learns a shocking secret from Deb.

After Lucas and Keith learn that Dan had a heart attack and is still in the hospital, they decide it is best for them to return to Tree Hill. When Deb learns about Haley and Nathan's marriage, she grows hostile. Meanwhile, angry that Lucas left Tree Hill without saying goodbye, Peyton and Brooke try to mend their friendship.

With the assistance of Peyton and Brooke, Lucas throws Nathan and Haley a wedding reception. Although Haley's parents support Nathan and Haley's marriage, Deb has a difficult time accepting it. Meanwhile, Dan's recent heart attack causes him to try and mend his relationships with Deb and Lucas.

Although Nathan and Haley are already married, Tim insists on throwing Nathan a post-wedding bachelor party, while Brooke throws Haley a bachelorette party. Meanwhile, Lucas tries to decide whether he should visit Dan in the hospital. Karen decides to go back to school and Nathan gets a job working for Keith at Dan's dealership.

Brooke tells the Latino pool boy he's not allowed to use the swimming pool, and when he gets out finds he was skinny diving- the next morning he turns up at her school in a sports car; it's her new neighbor Felix Taggaro, who is even more flirtatious, self-confident and sassy then she and uses Mouth to find his way. At college Karen gets to know personally her business economics professor Andy Hargrove, a retired self-made tycoon. When Lucas tells he wants to use Dan's rehabilitation to get to know him properly, Nathan gives him his blessing. Dan orders Keith to fire Nathan, to no avail. When Keith advises against the second hand car Haley and he hoped to buy, he generously spends the money on a keyboard so she can work on her composing talent- and gets barked at to take it back by his ingrate wife. Peyton gets a chance to manage a famous musical duo, but only if she supplies them with and uses cocaine. While taking a sports car for a test-spin, Dan makes Lucas accept Felix' race dare, and offers him the keys- which chases him away. Deb encourages Karen finally to start her long-dreamed bar extension to the café and is asked to help run it as a club. Now she's poor, Brooke is caught shoplifting but Felix saves her bacon. Keith offers Nathan to learn car mechanics by fixing together a car/wreck he intended to strip for parts, which Nathan may then keep.

Felix organizes a "dare night" to test the limits of his new classmates. While out playing the game, Lucas meets a mysterious new girl, Anna. Peyton tearfully confesses to the church that she recently tried cocaine and Keith is caught off guard when a beautiful woman comes to the shop and begins flirting with him. Meanwhile, Karen goes on a date with Andy, her younger professor.

Peyton meets cocky record shop clerk Chris Keller who turns out the only good musician on the club's auditions besides Haley, who has too much stage-fright. Coach won't listen when Lucas genuinely suggests to reconsider an eye operation. Lucas learns Anna is overprotective Felix' sister. Nathan gets a once in a lifetime invitation for the three months Highfliers basketball summer-camp in Florida. Now her parents are financially ruined, Brooke decides to recruit Felix as her purely physical toy-boy, and is forced to hold a garage sale. Dan invites Deb to watch the meteor shower together, Andy asks Karen, Anna gets Lucas to. Keith has a romantic date with his car-naive lady-client Jules. Nathan pretends to Haley not be accepted for Highfliers fearing they can't afford it and makes her overcome her stage-fright. When Dan realizes Deb is not ready for reconciliation, he pretends his actually excellent rehab-results are bad. Mouth proves his love for Brooke by buying back the doll-house she failed to overprice enough.

Felix continues to be Brooke's sex-toy. Chris makes Peyton beg for him to perform at the Tric club opening and hands her a 'rider' (list of demands), which inspires Brooke- about non-committal rules for Felix. Dan tells startled Karen he forgave Keith for sleeping with Deb, news to her. Keith asks Jules to the opening, they become exclusive. Coach, in hospital, understands Nathan gives up Highflyers for Haley's sake; seeing the crowd gives her major stage-fright, but when Chris leaves the stage because the teenage crowd won't listen quietly she plays, to applause, then he invites her to collaborate musically. Mouth hoped to get a shot at Brooke, but she commends him as a- sweet little brother, ouch; he accuses Felix, Lucas gets it backward and catches a solid punch, mainly for dating Theresa; Craig throws Felix out, Mouth brings drunk Brooke home, who only wakes up when Felix is beside her.

Brooke, Peyton, Haley and Anna have a slumber party at Haley's apartment where secrets and lies are revealed. Meanwhile, when Lucas and Nathan go on a road trip to a Bobcats game, Nathan reveals he is being tested for the genetic defect that caused Dan's heart attack and suggests Lucas do the same. After an awkward encounter with Keith and Jules, Karen and Andy share an intimate night together.

Haley makes Nathan agree to go to the prom even though his parents will be chaperons; Peyton pays Brooke's chosen dress for it; Lucas tells Felix he's taking Anna; Mouth comes alone 'on the prowl'. Lucas learns Dan is hiding his full recovery. Haley finally accepts to play with Chris in Peyton's club, but they run late, leaving Nathan dancing with his ma; when she finally arrives they are crowned king and queen of the ball but just then Nathan learns she worked with Chris even while he was in Charlotte, and ends up showing he gave up Highflyers for her. After Mouth tells her he, not Felix, took care of her while she was drunk, she's livid and tells Felix he'll never have her heart.

After the prom, Anna sleeps over at Peyton's- Felix sneers she's getting a worse reputation then his, while Peyton has a hard time with lesbianism-innuendos, even though Brooke says that appeals to boys, but ends up making a stand at school. Brooke finds Nathan slept on Lucas's floor; when he goes home, Haley tells him she respects his sacrifice and wants him to go to Highflyers, but won't do the one thing he asks, stop seeing Chris, so he walks out again and warns Chris in ominous terms and grip. Brooke blames Felix for her broken windshield and rages at him; he finds out it was Mouth, who also tells Lucas, but pays anyway; in the end he convinces her of his love. Dan takes the reins back at the dealership and offers Keith to stay on. Karen orders Lucas to take the medical test, or no basketball anyway- Nathan confesses he told her. Chris gets a chance to make a tour, asks Haley along and kisses her again. After Deb confesses her infidelity with him to Karen, Jules gets a call from Keith he loves her, and reports it to Dan

After Deb's confession to have slept with Keith, Karen shows her the door and later has a misunderstanding which makes her break up with Andy. Haley chickens out on her music career at the last minute, so Chris leaves alone. When she gets home, her older sister Taylor is there. Nathan hopes she won't remember she was his first sex partner at a party in the beach house. They become friends and he decides she can stay a few weeks. Jake is back, without Jenny, for a few days he spends mainly with Peyton. Lucas finds out how Jules' poverty drove her to break Keith's heart. Felix has a fight with Lucas for 'hurting Anna' -who later confesses to Lucas she's just lesbian but hoped to be bi. Karen and Andy ultimately make up.

Karen decides to make Lucas's life as miserable as possible till he takes the heart test and asks Andy over while his house is in a contractor's hands. Brooke needs a job- the Crab shack hires her, but not as waitress, just 'PR' in a crab suit; she quickly makes friends with the other underpaid girls but is the only one to develop a militant labor union attitude. Lucas confronts Dan about Jules, and is told about Debs adultery with Keith, who cannot deny it and swears Jules is his true love. Taylor sees Haley's tattoo and bugs her and Nathan about not following big sister's own advice in the past; when Nathan warns her to stop hinting at their first night she bitches back the full truth can hurt him more- so he tells Haley himself, who needs a cooling off period but then understands it was before they knew each-other; all three make up. Lucas confides about Jules to Anna, now he knows her lesbian secret. Keith offers Luke to take the HCM-test together, now Jules wants him to. Dan hosts and even cooks for a dinner with Keith and Jules, constantly getting at their and Deb's nerves, and afterward warns her Keith won't forgive her if he tells him their dirty secret; Keith tells Lucas Jules just accepted his wedding proposal. After researching regulations, Brooke starts hard action- they are all fired, and threaten to tell the public about his inferior crab supplies, and get a raise, but quits anyhow and turns her attention to Felix and running for student council president. Karen gives up forcing Lucas- and hears he just took the test.

Brooke plans her presidential campaign with Felix; her opponent is confident, never-defeated Erica Marsh, who lives for the job. Dan asks Lucas to move in with him while offering Keith to pay for a grand wedding with Jules. Nathan discovers lovers e-mail to Chris from Haley on their computer, believes her most are from Taylor and they decide the stirring sister must leave. Jake is back for good, moves in with Peyton and asks coach for a good word at school. Erika plays the campaign dirty, so Brooke decides to pull all the stops and asks Lucas to write her a killer speech- he suggest a J.F. Kennedy address. At the club Tric, Chris Keller is back, as artist opening act; he also dares Nathan about Haleys love, and once the main act 'the Wreckers' has asked him along on their tour invites Haley to join them- she tells Nathan she wants to, solely as a unique career opportunity, and is told to choose: the tour or him, and yet she goes. Karen fails to stop Lucas moving to Dan or at least find out why: he will pay for Lucas' medication, as he was not tested negative but showed her Keiths results.

Deb is angry to hear from Dan Lucas moves in, but hopeful now Haley has left Nathan he might also return. Nathan is a wreck, and seems determined to wreck his school-prospects; he won't listen to anyone, even hits the still taunting Dan. Jake and Jenny live in Peyton's room, but she is reluctant to become intimate again. Erica stops at nothing to defeat Brooke, but clever speeches by her and Mouth still turn the tide. Lucas seems to feel at home with Dan.

Coach tells the students of Tree Hill High to make a video recording for the traditional time capsule they expect to be open in 50 years. When Mouth tells it's sometimes opened early, Anna convinces him to help erase hers- they can't resist watching some other. Lucas moves in with Dan; Andy helps Karen to fight Dan in court, but she fails to remain rational. Nathan continues his self-destruction, believing Haley will never return, quits his job at Dans garage and gets Lucas and him arrested; they fight over Dan and Keith so Lucas tells his true motivation, and Dan understands when Nathan tells when he bails them out. Peyton and Jake go on their first date. Brook starts to really think about what she can do as president. When Jules tells Dan she'll tell Keith the truth, he says he may just keep off anyway. Jake and Peyton are becoming comfortable with intimacy.

Brooke is high: she's about to be installed as school president and her dad should get another well-paid job. Nathan, still drinking, is livid after a call from Haley she'll be on TV, refuses to go to Keiths wedding, gets no sympathy from coach -who even rats out his fake ID in the liquor store- and drives Deb to abuse pain killers, as Lucas soon finds out. Andy thinks Karen can get Lucas back now his detective found Dan pays all expenses for some Emily Chambers. Chris makes it appear on national TV as if he and Haley are a couple. Best man Lucas takes Brooke, Jake and Peyton are late as they are too horny, Nathan turns up drunk and cursing outside the church. When Andy learns Jules is Emily, Karen asks and guesses what Dan pays her for- Jules runs off, only Dan triumphs. While Nathan burns his memories of Haley, Deb tells him to go get her back. Brookes dad got the job- but must move to California next week...

Niki turns up with a court decision in absentia awarding her custody of Jenny- Andy offers Jake legal help as fleeing is losing. Lucas goes to his ma now the truth is out but decides to stay with Dan as he considers himself the enemy's only weak spot. Keith feels betrayed by everyone; Dan can't resist gloriously admitting having set him up and is physically assaulted. Brooke dreads her impeding departure and realizes she may stay with a friend; Peyton is willing, but her parents refuse. Anna turns Felix in to the principal for writing dike on Peyton's locker, with disastrous results: he is dumped by Brooke, his parents send him to military school, and Anna even blames him for not knowing she's the lesbian. Nathan drives to where Haley tours, pours out his heart ready to do everything for their marriage, but only hears she wasn't ready and right now the show comes first, so he returns. Lucas makes Brookes year: Karen and he take her in. Keith leaves, anywhere and maybe forever.

Lucas and Peyton hide Jake and Jenny at Nathan's place while he chases Haley. Lucas finds Dan's secret hiding place for cash and a secret ledger; when he and Andy come to get it at night, all is gone. Anna's former lover Darby turns up; she ends up coming clean to her parents, who still love her, but returns to boarding school. Nathan accepts an invitation to spend the night at the bar where Taylor works; they drink heavily and participate in the bar dancing show. Niki claims Jenny isn't Jake's biologically. Brooke stays late at a party without permission, misses her shift in the café, and learns to pay her debts and her dues chore-wise. Jake won't hear reason from his lawyer and chooses jail over handing over Jenny to irresponsible Niki, even if that's his best chance to get her back in a few months.

Deb's cool younger brother, race pilot Cooper 'Coop' Lee, visits his favorite nephew Nathan and invites him and Lucas to Lowe's Motor Speedway (now Charlotte Motor Speedway), where the boys and his kid brother Jarret get a crash course from competitor Ray Green's daughter Daytona 'Toni' in not crashing for a taste of the race. Dan informs college about Andy's improper relationship with Karen- he must choose and gives his notice. Mouth fakes being drunk so Brooke can 'drive him home'; Erica is a real client, and hits on with him, kissing. Dan finds Deb wasted in the garden. At the day of the (private) race, competitive athlete Nathan's pride is hurt, so he tries to break the track speed record but crashes with bad long injury; the doctors tell Deb her blood is too 'rich' in pills to donate; Toni thinks Nathan was suicidal. Coach tells Peyton Jenny is safe in a small Florida town.

While Nathan is unconscious in the hospital, he dreams a nightmare alternative version of his life, in which Dan married Karen and lives with her and Lucas, while Keith is the successful car dealer, Dan is assistant coach and trains Lucas as the Ravens star. Nathan is the poor underdog living with Deb -who runs the café- but may still be recommended for Highflyers by coach Whitey if he wins a duel; Haley is his girlfriend, Brooke makes a pass at him. Karen cheats on Dan with Keith. Peyton goes steady with Lucas but tells Haley to warn Nathan about Lucas' dirty plans; Dan's attempt to bribe Nathan off actually motivates him to fight, so he is abducted, bound and dumped by Lucas's Ravens hardcore. Peyton dumps Lucas, who loses the duel after she picked Nathan up.

Nathan is recovering and back home, but won't tell Lucas what drove him. Brooke pieced together a shredded invoice Lucas sneaked home, so she learns about his investigation for Dans car dealership scam, and Andy makes sense of it but feels Lucas should stop taking risks. Nathan was relieved to hear his hospital bills are all paid, when Dan bursts in; he refuses to move back home even during revalidation, but keeps annulment forms. The kids planned a benefit film night for Nathan's medical bills, and go on just for the fun; to their surprise he appreciates an accidental films switch showing car accidents. After talking to Peyton he wants to forgive his ma for fleeing into pills, as she begs in a letter, but understands his insurance wasn't paid, so he sees Dan who confirms he paid, the rent too, and ends up believing he could be on the road to becoming a bitter bastard like him if he makes the wrong choices; he even asks Lucas to back off his investigation and decides to return home; Haley got her annulment petition offered by Dan too. Andy shows Lucas the profits went largely in a college fund for him; he moves back to Karen when Nathan returns.

The class's last essay assignment is about what they lost during the year, which sets some thinking. Karen attacks Dan when she learns he tries to get Andy deported; Andy cleverly trick him to check the black books hiding place. Jake has high hopes to get Jenny back now his attorney found Nikki lied under oath about attending college; but the day before, Nikki visits him to show she found Jenny already... Coach encourages Nathan to go to Highflyers, as he has grown in character enough, but Dan claims his ma Deb will collapse again if he leaves after her return. Karens club TRIC fills for Jimmy Eat World. Lucas and Brooke visit New York for an overnight stay with Haley; Chris says they never had sex, but she refuses to give up her musical life. Jake tells Peyton to forget him as his quest for Jenny looks desperate.

Lucas and Brooke's relationship becomes more intimate when they travel to New York for an overnight stay with Haley.

Haley turned up at Nathans door, asking to be together again, but he is urgently called away to the fire in Dan's office- Deb asks her along. Peyton tells Lucas about Elisabeth who claims to be her -dead- mother but knows things; her dad now says her beloved ma was not her biological mother- she turns away from both. Three months later Brooke returns walking straight up to Lucas, who was however just waiting for Karen. Nathan finally can go to High Flyers, and Haley's declaration of 'never ceased' love doesn't get to him; but there he remains torn between his love for her and the shattered trust. Dan says in confession he will remember who drugged him and let him to die in his burning car dealership, and then...

Brooke has a end of the summer party on the beach; Nathan is home from basketball camp; Lucas deals with Brooke's rules for dating; Peyton deals with family issues; Haley tries to tell Nathan how she feels.

Lucas and Haley dig up, as each year, their previous predictions for the new school year; he decorated Brookes locker- they are arranged alphabetically, making the Scott brothers and Haley neighbors. Mouth pod-cast-interviews Ravens-star Nathan. Dan warns coach Durham he plans to have the school board remove him and Lucas he remembers his arson. Ellie tells Lucas the marijuana is for her cancer pain. When Haley asks coach for help with Nathan, he just gives her a detention slip for entering the boys locker room- Nathan is there to, but pays her no attention; next day, same place, they talk a bit. When dad Larry and Ellie wait for Peyton, she storms out blaming Lucas for 'trapping' her; left alone, dad makes her consider a shrink. Karen reminds Nathan how desperately he wanted Haley back. Dan tells the board the Ravens can be North Carolina state champions without Whitey, Karen praises his lessons on life for the boys- he stays on, but gives Mouth a scoop: he'll retire next year. When Dan nearly chokes Lucas, Peyton stops him and makes him tell he didn't start the fire but found Dan and dragged him out- Lucas now regrets that, Dan says a real man had left him and demands secrecy. Haley is happy to hear Nathan considers an annulment a lie, not when he proposes a divorce instead, hopeful again when he says the legal one year- waiting period gives them time to reconsider.

It's party time in Tree Hill. A masquerade ball at Tric provides the perfect opportunity for Haley to win back Nathan's heart, and for Brooke to seduce Lucas. Punk-pop sensation "Fall Out Boy" performs amidst the costume madness, while Peyton tries to come to terms with the new mother in her life. Meanwhile, Dan gives Deb an ultimatum, but soon finds she's a much more worthy opponent than he thought.

Dan presents the Ravens opening show for the new basketball season, but after the choreographed cheerleaders the boys come rolling in with a public fight between Lucas and Nathan over Haley; then a major flashback... Brooke and Peyton audition would be-cheerleaders; the obvious winner is arrogant, slutty Rachel, who Brooke accidentally indicates when telling Lucas to date another girl.

At the game, Dan is the only father who can't just enjoy being creamed by their heirs- he even barges in with the boys after their glorious first half, barking so badly Keith has to defend even Nathan.

Now Lucas is out of the coma and released home, where his ma tries to make him take it easy on doctors orders, Jake brings him a games console as a get-better-and-return gift from the Ravens and uses the opportunity to get a job in Karen's café. Nathan tells his ma he understands his parents' divorce is the only option by now, and turns all his attention to Haley, who makes him realize he's not a baby who must go where he's told but can legally choose; both parents seem confident and determined to win him over, but Dan convinces him Deb doesn't stand a chance because of her secret past. Lucas has decided to break up with Brooke -but didn't tell her- sneaks out to Peyton and collapses there; he is rushed to the emergency room, Brooke finds out and faces Peyton bitterly. Although Karen is determined to repay Keith Lucas' medical bills, since Keith 'can't repay' having endangered his life, he cashes in all his savings and plans a mortgage on his garage.

When the doctor tells Keith it's too soon to tell how bad Lucas's injuries are, he informs Haley, who throws Nathan out immediately and calls Peyton, who is with Brooke at the time.

Karen and Deb comfort each-other at Lucas's sickbed, where Peyton briefly and Brooke more elaborately meet Karen. After Haley gives him the silent treatment, Nathan sadly admits to Deb he barely minds she's separating from Dan.

Nathan says at Lucas's sickbed he envies him sometimes and suggests he make up with his loved ones. Lucas wakes up with Nathan on his bedside. Nathan goes to get Haley, telling her he doesn't regret having courted her for the wrong reasons as she changed him for the better, then gives her a ride to hospital.
