This article contains explicit discussion of Westworld Season 2, Episode 6, “Phase Space.” If you’re not all caught up, now is the time to leave.

Before we get to the big bombshell dropped at the end of this episode, let’s spend a few seconds unpacking the beginning. What we see is something that seems familiar, both from Season 1 and from the Season 2 premiere: Dolores (Evan Rachel Wood) and Arnold (Jeffrey Wright) having a chat sometime in the past. But it would appear as though Westworld is once again pulling the wool over viewers’ eyes. Just as last season, the writers tricked audiences into thinking those Arnold scenes were actually Bernard scenes, this season, they’ve tricked viewers into thinking they’re watching Arnold scenes when, in fact, it’s Bernard. Kind of. Here’s how the scene from the Season 2 premiere, shot in a different aspect ratio, began:

The aspect ratio part is very important; we’ll come back to it. We got the continuation of that scene this week when Dolores also revealed that she was the one controlling the conversation. Telling the character played by Jeffrey Wright to “freeze all motor functions” she reveals that this is a conversation they’ve had multiple times and that she’s testing for “fidelity.” That, of course, is the same language William (Jimmi Simpson/Ed Harris) used on the glitching, synthetic version of his father-in-law, Jim Delos (Peter Mullan), in Episode 4, when testing how the Delos consciousness he had uploaded was functioning in its Host body.

We can assume, then, that Dolores has done the same. She’s implanted Arnold’s consciousness into Bernard’s robot body, and she’s trying to make the transfer stick.

This episode ends with Bernard in the Cradle, and his skull conveniently empty of the gleaming ball that holds his consciousness. A flashback just before his head is cut open also implies that the mysterious red version of one of those mind balls (or “pearls” as they’re called in the show) was recently printed out and brought to the Cradle by Bernard. It’s all massively confusing, sure—but the implication is that Dolores has built herself a robotic, immortal version of her beloved Arnold and, it’s very possible that this is exactly who we saw wash up on the beach in the premiere episode: Arnold’s mind in a Bernard body.
