I have to go back and Re-watch the episode..I didnt catch the man in black say..He been coming there for years..I really thought he was a host looking for a way out.
So did I read the last scene wrong? I took it as Dolores being more aware than she has been putting on..Host aren't allow to kill living things and fly are living things.
Especially since the guy mentions she one of the oldest host in the park..I'm sure she's been through a lot..even more evident of this is them showing she now has a new father.
