Here's a look at tonight's sci-fi TV:
FlashForward, 'Blowback' – Rumor has it that FlashForward has somehow turned into a really good show, so now is probably the time to tune in. On tonight's ep, Zoe tries to change Demitri's fate while Mark questions Lloyd about their future conversation, and Aaron continues to investigate why the Jericho unit is after his daughter. (8 p.m. ET on ABC)
The Vampire Diaries, 'A Few Good Men' – Damon takes part in a bachelor auction to raise funds for charity (no, really), Stefan broods a lot, and Alaric confronts Damon about his dead wife. (8 p.m. ET on The CW)
Supernatural, 'Dead Men Don't Wear Plaid' – Dead men might not wear plaid, as the title of this ep suggests, but the undead sure do. Sam and Dean run into a mini zombie apocalypse when they visit Bobby's rural hometown. (9 p.m. ET on The CW)
