Is it wrong that I want the end to be an epic battle between battling armies of the small drones? With the battle ending when a drone belonging to an upstart rebel takes out Rehoboam with an impossible shot down a ducting vent that is Rehoboam's one weakness? Then a pan out to Dolores, Caleb, Serac, Maeve, Will, etc holding drone remotes and throwing them down in disgust while only one of them celebrates victory.
I mean it’s not the best solution but they did explain in episode that Serrac made that to stop Solomon from escaping.
This is very tinfoil-y but I had a dream last night that Caleb was the man in black and I think it's because I was thinking right before bed of the parallels between Francis and MIBs daughter and their relationship with Dolores along with their ID being the same and how "doesn't look like anything to me" could be flipped to peoples faces
