Here's a look at tonight's sci-fi TV:
Chuck, "Chuck Versus the Tic Tac" - The T-1000 himself, Robert Patrick, shows up on tonight's Chuck as an important figure from Casey's past. Chuck and Sarah team up to help Casey work a mission for his old handler while Morgan and Awesome help Chuck win back Sarah's heart. This sounds like a Casey-centric episode, which should please all the Browncoats out there. (8 p.m. ET on NBC)
