Here's a look at tonight's sci-fi TV:
Fringe, "The Bishop Revival" – The team is called in to investigate when a group of people mysteriously suffocate in a room full of air. Walter connects the incident to an experiment he was working on in Germany and later makes a shocking discovery involving the Bishop family and the Nazi regime. It's the Fringe team vs. Nazis, a showdown so potentially awesome that it makes up for the apparent lack of alternate dimension craziness in this episode. (9 p.m. ET on Fox)
The Vampire Diaries, "Unpleasantville" – The Vampire Diaries reminds us that it's nothing more than a gothed-up teen soap with another hour of bubbly high school drama. Damon and Stefan fight over who gets to slow dance with Elena at the sock hop while a crazy new vampire crashes the party. Sounds like somebody spiked the punch! (8 p.m. ET on The CW)
Supernatural, "Swap Meet" – Supernatural takes a cue from an '80s Fred Savage movie when a nerdy teen swaps bodies with Sam. (9 p.m. ET on The CW)
Archer, "Killing Utne" – Assassins target a UN intelligence chairman at Malory's dinner party. Also, Archer insults the help. (10 p.m. ET on FX)
