Decent episode, not great. The Maeve storyline is butchering the show. It's just reached "The Matrix Revolutions" level of retardation. The two tech dorks are just too much and that storyline is beyond unbelievable (unless it's somehow part of Ford's new narrative, which would at least make it tolerable).
The more they try to make it seem like William is the MIB, the more I'm starting to believe he isn't. They went out of their way to point out that the girl in the new narrative is one who the MIB recognized from a long time ago (like when William first came to the park). That clue almost seemed just too much like a blow over the head, not subtle or nuanced whatsoever, almost like they're now daring the audience to believe that William=MIB. Also, when Dolores makes it back to the town, and William snaps her out of her trance, the church is buried just like it is in the present, which makes it difficult to now believe that William is in the past. Unless of course Ford buried the town shortly after the park opened, in which case William being the MIB is still in play.
I liked the stuff with Bernard, I liked the stuff with the MIB killing Maeve to create his own story, which is when he first discovered the maze, but the stuff with Maeve and the tech nerds is really, really cringeworthy.
