What is the door?
The more consequential (and interesting) Man in Black scene occurred later in the episode. Now that the hosts of Westworld are free, the gameplay aspect of Westworld has been transformed -- or, at the very least, modified. He found the maze; now, it's time for a new, more challenging task. It sounds like the Man in Black's mission this year, which he received from the young android version of Robert Ford we met last season, will involve returning to his point of origin. According to the little robot boy in short-pants, the Man in Black must head for "the door."
The Man in Black tells young robo-Ford that he feels like he's "just arrived," and that only now does the game have "stakes" and "real consequences." Ford replies a bunch of cryptic instructions delivered in a warbly, vocoder-ey voice. "In this game, you must find the door," he says. "Congratulations, this game is meant for you." He also said something about the game ending where it began. So, what exactly is this door and where is it? Given the fact that the "maze" from last season ended up being more metaphoric than literal -- no corn maze in this theme park -- you should probably bet on this "door" being something more figurative and poetic than just an empty door frame. Maybe it's a portal? A state of mind? The next step in upcoming robot revolution?
Even more than the "door" comment, the young Ford's comment about how "everything is code here" should make you pause. Like many lines in a given Westworld episode, it sounds like a vaguely philosophical koan you'd see on the wall of some Silicon Valley start-up, but it also functions as potentially brain-scrambling clue in a larger mystery. (Merely hearing the word "code" made me think of The Matrix, yet another sci-fi story about a chosen one leading a violent coup against all-knowing overlords.) If everything's code, does that include the park? The hosts? The Man in Black himself?
Unfortunately, the Man in Black doesn't ask any of these questions. He's not exactly the show's most curious character. Instead, he shoots young Robert Ford, sending him to the great scrap-heap in the sky. It turns out violence is the only code he knows.
