Corky tries to mainstream into the 9th grade, the same grade as Becca. Becca worries that Corky may stop her from getting to the boy she really wants, Tyler Benchfield, a star on the football team. Corky dreams of being King at the homecoming dance with Ron Lieberman. Corky is accused of cheating off Rona's paper but it was exactly the opposite. Tyler introduces the Thatchers to his brother Donny, who also has Down's Syndrome. Doubts arise arise over whether Corky should indeed mainstream as opposed to going into a special-ed program, or a private school (which the Thatcher's can't afford). But at a serious parent-principle meeting, Corky dispels all doubts by reciting ""The Raven"", the famous Edgar Allan Poe poem.

Sub-plot: For Libby's 40th birthday, Drew buys her a heart-shaped ring that they can't afford. Paige moves home.

Corky runs for freshman class president with the help of an unpopular, smart student,Lester Fishbein. He has a crush on Rona and really believes that Rona likes him as well. Rona encourages him to run and Corky doesn't realize she's just joking with him.

Corky gets a babysitting job; his classmates barge in at the house where he is babysitting. The intrusive folks include Tyler, who regrets the whole thing, and ""Russo"", who is basically a jerk/nemesis.

An episode showcasing the singing talents of Patti LuPone. A Tony winner for the musical ""Evita"", actually centers around Corky, for whom nothing seems to be going right. First, he has an accident in driver's ed. Moreover, he's not doing well in his remedial arithmetic class, and if he doesn't pass a minimum-competency test he won't be able to stay in the mainstream program. What really gets to Corky, though, is the uneasy feeling that his mom gave up a promising show-business career because he came along. As it happens, Libby has a chance for a comeback of sorts, at the community college's ""Autumn Follies"". She wants no part of it. And Corky doesn't want to take arithmetic tutoring with kids ten years younger than himself. But they work out a deal: he'll take the tutoring if she auditions for the show.
