Fringe
Fox, 9:00 p.m. ET
Any time Anna Torv, on this show, is sporting long reddish brown hair, that means we’re watching the “other” Olivia. And this week, we meet a new alternate-reality doppelganger as well. By now, after all the recent cross-universe traveling by lookalike characters, it’s safe to say the doppelgang’s all here.
