Here's a look at tonight's sci-fi TV:
Lost, 'Happily Ever After' – Say it with me, folks ... The island isn't done with you yet, Desmond! Mr. Desmond Hume, one of my favorite characters on Lost, heads back to the island tonight. Word is he won't be the only missing player returning to the show in "Happily Ever After." I won't give away who's coming back, but if you really wanna know, you can find out by perusing the guest cast list. (9 p.m. ET on ABC)
V, 'Pound of Flesh' – The rebels hatch a plan to infiltrate the enemy ships when Anna offers select humans a once in a lifetime opportunity. Valerie's pregnancy continues to accelerate, and Tyler stumbles across a secret. (10 p.m. ET on ABC)
