Well, now we know why Caleb was having those weird flashbacks. He was used by the Solomon/Rehoboam system to hunt down and capture "outliers" and then they "reeducated" him and altered his memories. When Caleb mentioned the EMP early in the episode, I said out loud "Chekov's EMP" but then I completely forgot about it until it was pressed at the end of the episode. I wonder how Dolores and Maeve get rebooted after this. Presumably Serac will have a way to reboot Maeve, but who would be in a position to reboot Dolores? Charred-lotte? Bernard and Stubbs? William? Watching the Inside the Episode thing at the end, they made it sound like the fight between Maeve and Dolores was supposed to be some huge, epic fight, but it didn't really seem all that impressive to me. I guess all the ridiculous, unrealistic action movies have ruined my perception. So how does this all wrap up next week? Does Serac get defeated or is he still the big bad for S4?
