Cate finds herself once again in the awkward position of having to deal with Principal Gibb when she forgets to turn in a health form for Kerry's trip to Europe. Meanwhile, Cate is resentful of Jim's relationship with Tina because she still hopes that her father will reconcile with her mother, and Rory plays a nefarious joke on C.J. when he sets him up with girlfriend Missy's already engaged sister, Sissy. When Cate discovers that Bridget took the fall for Kerry for organizing the school sit-in, she agrees to have coffee with Principal Gibb in order to set the record straight. But the girls are convinced that their mother's innocent coffee meeting with their principal is really a date. Meanwhile, Kerry is furious when Bridget is elected student body president and wins a trip to Washington, D.C. -- because everyone thinks she organized the school sit-in -- C.J. keeps deluding himself that he's been chosen to be a roadie for Aerosmith over the summer,
