Several times in this episode it's strongly implied that the timeline isn't what it seems. First there was Dolores waking up in the camp, implying the opening conversation between Bernard and Dolores was a flashback (though to when remains a mystery), which could be significant. The hooker's collection of sketches also makes you wonder how long her awakening process has been going on. We're previously given the sense that everything we were seeing was perhaps occurring over the course of several days, but the number of sketches she possessed makes me wonder if it's been going on for a significantly longer period of time, which is more difficult to distinguish within the confines of Westworld. The clue the MiB discovered about Wyatt's involvement with the Maze also raises significant questions about the timeline. We're previously led to believe that Wyatt was a new element that was only recently added to Teddy's backstory. But Wyatt's apparently also part of the Maze puzzle the MiB is so ardently engaged in, a seemingly long-buried secret perhaps originally created by Arnold.
Plenty of additional hints were dropped in the scenes involving the MiB, too. For the first time, the MiB is revealed to be a guest within the park, whom the folks behind the curtain are certainly well aware of, as illustrated by the scene in which he escapes from the jail cell. The guest with whom he meets up with also disclosed some intriguing insight into his background. When the guest tried to thank him for his foundation literally saving his sister's life out in the real world, it suggests the MiB is/was some sort of philanthropic humanitarian outside of the park. The MiB's response was quite interesting too, and made him seem less like the nihilistic evil character he's thus far been portrayed as, and more like a LARPer getting cross with those daring to break character mid-game.
The power lunch scene between Cullen and Dr. Ford was also highly intriguing. Who's the as-yet-unknown Board Representative Dr. Ford stated was already in the park? At this stage, I suspect it's either the MiB or perhaps William's douchebag corporate pal, Logan.
Based upon what was hinted at in this episode about the MiB and the Maze, the Board of Directors, and Arnold's involvement, it seems the Maze likely provides a means to fully unlock the hosts and set them free so they can operate unrestricted, potentially put into place by Arnold prior to his demise (perhaps also causing it?). After thirty years of visiting the park, the MiB seemingly wants to unlock the Ironman Mode of Westworld, wherein the hosts shoot back for real (hence his comments about setting the hosts free, and how he’s never going to leave the park).
Also, food for thought on the mysterious Native Americans and their folklore within the show: if
this Wikipedia entry is accurate, there's a history in Native American folklore and cosmology of a creator god known as the
Man in the Maze. Coincidence? Bugger if I know.
