lost Ab Aeterno richard alpert

Here's a look at tonight's sci-fi TV:

Lost, 'Ab Aeterno'
– The flash sideways take a backseat as we flash back through the very, very long life of one of Lost's most intriguing characters, Richard Alpert. Last time we saw Richard, he was still reeling from Jacob's death and the realization that his life is probably meaningless. Tonight we'll learn more about the ageless Other's connection to the Black Rock and explore his relationship with Jacob and The Man in Black. Elsewhere, the castaways learn that they're all "candidates" to replace Jacob, but none of them seem very thrilled about taking the job. (9 p.m. ET on ABC, tonight's ep runs through 10:06 p.m., so remember to adjust your DVR timer for the extra minutes.)

V, 'The Arrival' – ABC's V redo heads back to the tube on Tuesday, March 30. Prepare for the alien invasion with tonight's recap of the first few episodes. (10 p.m. ET on ABC)
