Yeah, I'm starting to think the new narrative actually involves Dolores and MIB, the maze, "remembering", all that stuff.
I started a rewatch yesterday (had only seen every episode once), and in the scene where Ford turns down Sizemore's new narrative, he talks about how people want to find things they think are not meant to be found, etc. Pretty solid evidence that the maze (and possibly even Maeve) are all part of that new narrative. Somehow this hadn't occurred to me until I rewatched that scene. Now it seems obvious.
So, my theory about the guys working on Maeve being hosts is still in play, but now I think they're working for Ford instead of the board. It's "all...part of the plan."
Still not smart enough to see what the big picture is, though. Much like Sizemore.
