Unless we get some kind of explanation as to why bullets literally threw William backwards and left a giant welt on his chest, and why his brother in law was getting beat the fuck up by hosts, there's still a good chance these stories are asynchronous.
People that misbehave in the main town get throw in jail, they also don't get injured by bullets.
The further out you go the more consequences the guests have to bear, beatings in the criminal town is one of those things. Getting mild bruises from gun blasts is another.
It would stand to reason that the "war" setting on the edge of the park has the highest stakes the park has to offer.
So, I don't know why those things would indicate the mib=william theory.
Anyone want to try and explain this observation from the subreddit?

William and Lawrence are missing from the scene in the second shot.
She's speaking with Arnold, or recalling something that changes her perception like with the fortune teller. She's basically disconnected from her surroundings.
I'm guessing viewing the maze emblem triggers something within her each time she sees it.
