The school bully experiences a severe lapse in judgment when he tries to sexually harass Mary.

Playing in the park with cute little Billie, handsome student Wilson West meets Mary and both get butterflies. Wilson's impeccable charm, doctor-pa and record pass even Eric's paranoid muster, but on Sunday he divulges that Billie is not kid brother but his own son. At the airport to pick up maternal grandpa Charles Jackson, Matt is smitten at first sight on a girl he later traces and learns is deaf Heather Cain. They date, but she flees the party after some youths make fun of her sign-language. Eric and the kids welcome grandpa's new 'significant friend' Ginger, but Annie irrationally rages against any suggestion a successor for her ma could be less then diabolic.

Wilson West tells Eric that Billy is his son, unplanned but not unwanted, whose teenage mother died giving birth to the angel, which his parents help him raise. Dating privileges are maintained 'for observation'. Michael Towner bravely owes up being the one who accidentally hit Mary when she dashed after Annie, who realizes she's the guilty one but only tells off Matt's overprotective vindictiveness. Sign language in a deaf-run restaurant helps Matt patch up with Heather. Jimmy Moon dumps Lucy on account of her endless hair wining. Charles Jackson nearly lost hope Annie would turn round and Ginger imposed 'a break', but both women come to their senses after some surprising 'counseling' and fibs. Mary is released home, but recovery up to basketball level is far from certain.

Simon wants to buy the perfect gift for Deena; Lucy's ex-boyfriend is spending time at the Camden's home; Heather is engaged.

Simon plans a fancy-restaurant dinner to celebrate Deena's birthday; when her college-musician big brother comes along as chaperone, Lucy eagerly accepts his invitation to join them. Matt joins Sargent Michaels on nightly patrol and hides to avoid being seen by frat friends and freaks out when he discovers Mary kissing her 'movie-date', Michael Towner, in the police car. Eric promises elderly Burt and Cheryl Carberry that he'll take their beloved dog 'Mom' to be euthanized, but when he can't bring himself to, they end up in the park meeting a stray Labrador who is fleeing from abuse.
