Episode 4 airs this Sunday, October 23, but we already have our eyes on Episode 5, thanks to Dolores herself, Evan Rachel Wood.

(And they certainly are speculating -- from the theory that William is the younger version of the Man in Black, to the idea that maybe the Man in Black is park co-creator Arnold, and a dozen other theories in between.)
