The following contains spoilers for Westworld Season 4, Episode 3, "Années Folles," which aired July 10th on HBO.

One of the most intriguing aspects of Westworld has been the revelation behind Bernard. He was actually a host/robot modeled after co-creator of the Delos park, Arnold, thanks to Arnold's best friend and fellow architect, Ford. Before he died, Ford wanted to push the existential boundaries of robotic sentience and A.I., playing his own warped game in honor of the dead Arnold. In the process, he made Bernard a Chosen One to liberate the hosts, which Dolores realized.

However, Bernard couldn't go along with Dolores' apocalyptic plans to destroy mankind, taking them down different paths as she was killed. As such, Season 4 found him reawakening into a world Dolores inadvertently shaped -- one which Halores/Charlotte (aka the evil Dolores) and William 2.0 are trying to make their own, but while it seems Bernard is short of allies in the new world, one of them may have a shocking secret of her own to come, and this theory revolves around the rebel Bernard and Stubbs encountered in the desert

Westworld season 4 Caleb and Maeve

Bernard's been using his experiences from the Sublime (a Matrix-like world where Dolores sent host minds for haven), deciphering mankind will fall if he doesn't intervene. This led to him predicting the rise of the rebellion, but also, problems they'll encounter. As a result, Bernard killed a couple rebel members, revealing they were hosts.

He offered them up to the rebel, who reluctantly agreed to put her guns down and take them to the rebels' sandy base. It felt very Terminator-like, with Bernard telling the squad he knows their mission is to stop the current predicament. He doesn't specify what it is, but it's likely Halores' evil bots infiltrating society, replacing America's elites and politicians, and brainwashing mankind using flies. Bernard then confesses he has knowledge of some weapon they seek, and he can help the resistance find it in the desert.

Now, what's interesting is Stubbs senses Bernard's looking to this rebel as a Chosen One, but this doesn't seem to be random. In fact, she may well end up being Caleb's daughter, Frankie -- someone Bernard could have predicted would change the outcome of the war. This twist could arise due to Westworld's classic sleight of hand, telling connecting narratives in different eras. The Caleb-Maeve timeline seen thus far had them taken by Halores and William, with Caleb turned into a pawn via the flies. However, it's easy to see Maeve escaping and finding Frankie and her mom, Uwade, on the lam.

Frankie could be helping Bernard in Westworld

Maeve could have then trained Frankie, who was seen using toy guns because she wanted to be a soldier like her dad. It'd give Maeve the daughter arc she never had in the real world after hers was murdered time and time again in the Delos park. This would allow her to hand off her and Caleb's legacy, building to the second timeline in the future where an older Frankie changed her identity and became this freedom fighter that Bernard met.

What really speaks to this theory is Frankie and this rebel look so much alike; plus, they have that resilient persona Caleb embedded. Ultimately, this would be a fitting passing of the guard as Westworld has very much been a female-driven story. It would also allow Aurora to get revenge, according to the dark fates teased for her dad and Maeve, while enabling her to bring down the evil, controlling empire Halores built.

New episodes of Westworld debut 9pm ET/PT Sundays on HBO and HBO Max.
