Here's a look at tonight's sci-fi TV:
Lost, "What Kate Does" – The flash sideways continue as Kate goes on the run again, leaving Claire stranded in the middle of L.A. Back on the island, Jack tries to get answers from the other Others and is put in a compromising position. Elsewhere, Sawyer deals with Juliette's passing, and Smoke Monster FLocke (Fake Locke) is still very disappointed in Team Jacob. (9 p.m. ET on ABC)
