FX, 10:00 p.m. ET
A future version of Syd (Rachel Keller) fears that the powerful mutant psychic David (Dan Stevens) is the reason the world ends, and travels back in time to kill him before that happens. David, meanwhile, hopes that if he travels back in time himself, he can put things right, and establish a new time line that doesn’t involve destroying the planet. And in the weird world of Legion, it’s quite possible they’re both right… Regardless, this is another stunning episode of Legion...
