Here's a look at tonight's sci-fi TV:
Lost, 'The Candidate' – Jack and Locke grow closer together in the Sideways world while they grow further apart on the Island. Of course, that's not really Locke on the island ... or is it? Is it possible that there's a part of John Locke still kickin' inside of ol' Smokey's brain? Or maybe Locke will return to defeat the imposter once the Sideways world finally collides with the Island world. Or maybe I should just shut up and remind you that we have two clips from tonight's ep after the jump. (9 p.m. ET on ABC)
V, 'Hearts and Minds' – Anna sends a shuttle full of dangerous V trackers ready to wipe out the resistance Erica and co. must figure out how to stop it from landing before the trackers start to take them down. Elsewhere, Anna gives Tyler his Live Aboard pass and I scream "Die Tyler, die!" at the TV until I pass out. (10 p.m. ET on ABC)
