ABC Family's Greek seems to be preparing a full curriculum of trouble for next semester.

Recently, I reported that Charisma Carpenter's ZBZ rep will return in the fall premiere to mediate a tense matter between Casey and a new pledge. But were that Ms. Cartwright's only new headache!

Michael Rady of Sisterhood of the Traveling Pants (and who also has been playing Swingtown teach Mr. Stephens) is joining Greek next season as a new character who will stir up trouble for Casey... as well as for Rusty. How exactly will Rady rock the siblings' respective worlds? I'll take that question on as an "extra credit" assignment. - Matt Mitovich
