ok here’s my take (see my edit above) Bernard is running simulations and is leaving himself clues to get further each time. It was revealed this is actually happening from the “sublime” which is the server farm inside the dam that Dolores built seasons ago for the hosts to reside. He’s dangling this in front of Maeve but it’s unlikely she gets there as Bernard knows he dies. Jesse is a fidelity-programmed “host” just like the Man in Black, on his nearly 300th iteration so host Charlotte might be able to get information from him on how he initially resisted her flies. Christina/Dolores is likely also in a loop like this. Teddy confirmed as much (said she wasn’t real) and she wasn’t attacked at the end. Charlotte could be using her to get into the sublime.
