At the end of the episode, William is seen entering the Delos lab, where he finds Charlotte (who’s actually Dolores) making a new generation of hosts. Just then, robot William emerges from the shadows wearing his famous cowboy hat. The Man in Black’s confusion is evident, since he isn’t aware that Delos made a copy of him.
So, what does it all mean? We’re not entirely sure, but it does confirm that Dolores’s reason for locking up William in the mental institution is far bigger than we suspected. In fact, we think we’ve been watching multiple versions of William over the past three seasons—not just one.
It’s pretty far-fetched, but it would explain the character’s rash actions, followed by years of regret that he tried (and failed) to drown with whiskey. If host William (not human William) is responsible for his wife and daughter’s deaths, it would account for his countless visits to the theme park in an attempt to figure out what happened.
We assumed William couldn’t remember because he blocked out the memories, but what if he never committed the crimes in the first place? If Delos set him up, it would explain why he can’t decipher reality from fantasy.
Showrunner Lisa Joy further confirmed our suspicions during a behind-the-scenes video, saying, “The man who has toiled under the weight of his dark impulses is free from them, but Hale has plans for him. Who better to control it and puppeteer it through than The Man in Black?”
So, Charlotte has been treating William like a puppet? This makes us question everything.
