Terri is not looking forward to the school dance. She's too fat for any boy to like her, except for Spinner, that is. Too bad Paige likes Spinner too. She convinces Terri to go to the dance, but not before getting her drunk, so she'll look like a fool in front of Spinner. There's also a new student in Mr. Simpson's class: Sean Cameron, who has fallen behind a year. Emma is intrigued, despite Sean's "bad boy" image. Meanwhile, J.T. and Toby decide to skip the dance to surf pornography on the Internet.

Toby can't stand the idea of Parents Night - the last time his divorced parents were in the same room they had a huge, embarrassing fight.

It's final exam time and everyone is stressed out. Especially Sean.

Spike and Snake are finally getting married! Emma is thrilled to be her mother's little helper for everything wedding related but it seems like all their plans start going wrong as the date draws nearer. As if stress about the ceremony wasn't enough, Spike finds out she's pregnant and struggles with whether or not to tell Snake.

Emma takes matters into her own hands and tells Snake about the baby. Snake and Spike have a long talk and decide the baby could be a blessing for them. The happy couple makes it to the ceremony just in time to walk down the aisle in their jeans and T-shirts. The crowd cheers as Spike and Snake kiss, ready to face any difficulties the future may bring.

When Emma agrees to get back together with Sean, he feels like he is on top of the world. Unfortunately, Sean's happiness is short-lived when his home life becomes more desperate and alcohol becomes his coping mechanism.

Snake's illness is causing a strain on Emma and Sean's alone time. Sean, feeling lost without Emma's support, has thoughts of his old troubled life. He starts to gravitate toward trouble-makers Jay, Alex and Towerz. A fight with Emma over their lack of time alone together turns Sean's thoughts into reality. Sean does whatever he feels he needs to be to be accepted, an act which ends up hurting Emma. Meanwhile, J.T. is hanging out with the in crowd - his new friends - leaving Toby in the lurch. At a sleep-over at Toby's, an embarrassed J.T. has a wet dream over Liberty, which Toby lords over him as blackmail in also being able to hang out with the in crowd.

Sean chooses to move out on his own, meanwhile J.T. attempts to ask Manny to the dance.
