Forget cold feet. Chuck's got a cold bride-to-be! In the May 16 season finale of NBC's spy drama Chuck, the altar-bound Chuck and Sarah (Zachary Levi and Yvonne Strahovski) run into a hitch, courtesy of an evil uninvited guest. "After Sarah is poisoned by Vivian Volkoff, Chuck has one final moment with his fiancée," teases executive producer Chris Fedak, chilling us with his use of final, as the show has yet to be renewed for next season. Could this be what they mean by "Till death do us part"?
