In its first season, Westworld found itself on its back foot a bit as eagle-eyed Redditors stayed one or two steps ahead of the mysterious HBO series’s twists. This year, however, the show’s writers seemed to redouble their efforts to keep in front of the fandom—and, for the most part, they did. There was a last-minute host reveal, a mind-bending end-of-credits stinger, and some subtle clues hiding in the weekly opening credits. Just last week, in a special episode of Vanity Fair’s podcast Still Watching: Westworld, Insider’s Kim Renfro also floated the idea that Dolores might have been hiding inside a replica of Charlotte Hale’s body, based on a two-second glimpse of double Tessa Thompsons in the season-finale trailer. But Hale as some kind of Trojan horse for our Dolores was hardly a popular guess this year.

That’s because the show mainly kept the masquerading Charlotte (or, as the Westworld writers call her, Halelores) out of sight. She only appears in three episodes total, including this week’s finale: altogether, she has two scenes in Episode 3, just a handful in Episode 7, and then the finale reveal. But once you know where to look, the clues are both subtle and fun to spot.

Co-executive producer Fred Toye tells Still Watching that after Thompson, Evan Rachel Wood, and the show’s creators, Lisa Joy and Jonah Nolan, all discussed the Dolores impression, they made a decision to keep it as under-the-radar as possible, perhaps so as not to alert the Redditors. As Toye said, “My favorite moment was the scene on the beach with Stubbs, and they use this little moment of hers where she gives the smallest of small dry smiles. That was totally Evan.”

What about some of the other Halelores hints along the way? Well, our first glimpse of her in Episode 3 did set off some alarms for fans. Her sneering “Bernard, I didn’t think you had it in you” felt a bit hostile and knowing for Charlotte, so audiences figured something must have gone down between the two of them. But there were so many possibilities as to what that might be.

More to the point, there’s a patented lean-in maneuver that Dolores posing as Charlotte uses more than once on Bernard. She’s inspecting him so closely—almost like a raptor that would devour him. We’ve seen the CR4-DL version of Dolores give Bernard the exact same look.

There’s also the oddly tender look Halelores gave Bernard’s hanging robot bodies in Ford’s underground basement. Remember that despite all the terrible things he did to her—including shooting her in the head—Bernard is still something Dolores helped build, and is still an identical physical copy of her beloved Arnold.

Once Bernard’s host status is revealed—something it would seem Halelores had a hand in engineering—she interrogates him in a way that’s fascinating to re-watch. Never mind this juicy clue . . .

. . . or the fact that (and this is admittedly more of an auditory clue) when Bernard is coming out of a daze, you can hear both Thompson and Wood call out “Bernard” in rapid succession.

Then there’s the Episode 7 interrogation itself. While there are certain repeated phrases we, as audience members, are quite used to hearing during a host interrogation, Halelores uses some very specific language that we’ve only really seen used on Dolores in the past. She recalls phrases from both Stubbs and Ford as she grills Bernard for answers on where the Abernathy control unit is.

After this, Halelores offers Bernard a solution. They’ll both try to see what they remember from the invasion at the Mesa a few days ago. “I’ll tell you what I remember, and you tell me what you remember,” she suggests. That would imply the rest of the episode, told in flashback, should be from either her perspective or his. But wouldn’t you know it, some Dolores memories snuck in there too.

We can also rewind and, if we’re rooting for Dolores—and especially done with Charlotte after she killed poor Elsie—then we can take perverse pleasure in the fact that Dolores managed to make good on her Episode 7 death threats.

It’s also worth noting that Westworld made sure to set up Hale’s body as one that would surely get by the scanners on the beach. When Charlotte was still Charlotte, she passed with flying colors in Episode 3.

Not only that, but hers will, of course, be a very valuable body to have if Dolores is intent on further dismantling Delos Inc. In the finale itself, the clues get a bit more obvious with the reveal right around the corner. There’s the extremely worried look Halelores shoots the mechanism set to upload data to a Delos satellite . . .

. . . and the clever time-hop jump between Halelores and Bernard riding the elevator down to the Forge in the present day, and a quick cut to Dolores and Bernard arriving via said elevator in the past.

Only one final Charlotte/Dolores question remains. If the Dolores pearl, which was once inside a replicated Charlotte body, is now back inside a body that looks like Wood, then who, pray tell, is that menacing person holding a gun and looking like Thompson in one of the final shots of the episode?

Well, there are a few possibilities. One that I dare not cling to is that there are now two Doloreses. What fun that would be! What’s much more likely is that Dolores has inserted one of the pearls she smuggled out of the park into this perfectly hearty and Hale body she had lying around. As we mentioned, it’s a valuable body to have if corporate espionage is on the table.

So, who might it be in there? Well, gosh, Westworld will probably keep us guessing well into Season 3. With Angela exploded and Teddy uploaded, the sidekick options are limited. “Yeah,” Toye says of Dolores’s mysterious string of pearls, “100 percent totally a tee-up for Season 3.”
