While on spring break, Beth volunteers to help build houses for needy families. Abby spends time with Iris, and Kevin's half-pipe plans turn out to be rather problematic.
Kevin's older brother, Randy, visits from college with a lesson for the gang, and Abby finds herself becoming a muse for "shoe-gazer" Derrick.
Animals suddenly have the ability to talk; Abby develops allergic symptoms because of her job at an animal shelter; and Harold dishes out gossip using a blog written under the alias of "The Fly."
Beth runs against Phillip for student body president; and a handsome civics teacher sparks Abby's interest in politics.
Kevin's integrity suffers after he gets his dream job as a shock jock's sidekick. Meanwhile, Abby and Harold volunteer to help children who don't have siblings.
