Interlaid with all this is Serac’s officially successful effort to take over Delos, scooping up all the data, destroying almost all the hosts, and attempting to root out any potential Dolores clones. In William’s case, though, it means a trip down memory lane, returning to his youth spent absorbed by books, an abusive father, and his own inner darkness.

This technology’s ability to control a person’s basic biology was shown earlier, when thugs were torturing Caleb by activating his own grill and ramping up his heart rate, and the smart bet is that this technology is likely a key part of how Serac plans to reprogram people who don’t fit into his system. The device that’s implanted into William’s mouth, by the way, is something you can read all about on the Incite website - it’s what interacts with the “limbic tabs” we’ve seen people, including Caleb’s mother, take over the course of the season. While William’s psychologist dies by suicide after getting a copy of her profile (as well as getting a text from her partner disconnecting her from her children), there are still enough professionals around to keep seeing to his treatment. But then the field expands to check in on William, trapped in the mental health facility to which he was sent, though things become chaotic once the ripple effect of Dolores’s data release spreads to them. Things begin with Maeve still firmly under Serac’s control, waiting for her new body to be loomed after dying at the hand of Dolores in episode four, and keeping busy by imagining her reunion with her daughter, as well as fighting Nazis. Instead, it’s time for a deep dive into him as a person, with assistance from his past lives (including a very welcome cameo by Jimmi Simpson). Despite being called “Decoherence,” this is a relatively straightforward episode of Westworld - one that’s largely about the characters left behind by last week’s apocalyptic brouhaha, and catching us up to where things stand with them. And that includes folks like William, whose story one might have thought had reached something of an endpoint.
