Here's a look at tonight's sci-fi TV:
Chuck, 'Chuck Versus the Living Dead' – Shaw might have gone bye bye a few weeks ago, but that's not stopping him from haunting Chuck's dreams. Chuck teams up with Morgan for a new mission to stop the nightmares, but things get complicated when his father (guest star Scott Bakula) returns, putting Chuck and his friends in danger. There are only two episodes left until the season finale so remember to tune in, Chuckleheads! (8 p.m. ET on NBC)
