While the Thatchers rise from the ashes of the restaurant, Becca prepares to take wing for Paris in a student-exchange program, and Paige and Corky go hunting for jobs.
Becca, Libby, and Paige have entered the "man zone" as they tear down a wall in the Thatcher house to reveal another room and the mementos left behind.
The Thatcher home is struck by lightning which results in Corky predicting the future, Arnold the dog running away, Becca with a major static problem in her hair, Drew attracted to another woman, and Paige enchanted by the boss' son.
The holidays take on a whole new meaning for Corky, who's celebrating his first Christmas as a married man and now has the wishes of a wife and in-laws to consider.
Encouraged by Rona Liberman, Corky runs for freshman class president with the help of smart, but very unpopular classmate, Lester. Thinking that Rona likes him, Corky doesn't know he was only nominated by her as a joke.
Corky gets his first babysitting job. Unfortunately, things don't go as planned when classmates Tyler and Russo show uninvited up at the house where he is watching young Billy Graber.
Becca and Corky are paired off with other students who must pretend to be engaged for a week to investigate issues of marriage and family life. Meanwhile, Libby's feuding parents hole up at the Thatcher residence.
The Thatchers toast the reopening their newly-renovated Glen Brook Grill, but their dreams go up in smoke when the restaurant burns down and Corky finds himself at fault.
Corky is nearly swamped when he tries to help Tyler's brother Donny, who also has Down's, mainstream at Marshall High. Meanwhile, Tyler's difficulty adjusting to a repeat of his senior year causes friction between him and Becca.
