The "Westworld" TV series concluded in a similar manner it did when it premiered 10 weeks earlier, but longer and with more violence. In "The Bicameral Mind," we learned that the man in black, William, portrayed by Ed Harris, pursued Dolores to reveal to her Wyatt's location and the center of the maze. It was at this point when the man in black revealed himself as the old William.
There was flash of memory where Dolores was given the order to kill him and to wreak havoc on the park. Then it was revealed that she is Wyatt. In the premiere episode, "The Original," the man in black attacked both Dolores and Teddy as he searched for the maze's location. The episode provided a peek into Westworld, a theme park occupied by "hosts," or artificial beings. It ended with Dolores, being cleansed and having relived her day knowing another father, as Peter, the father she knew, was retired. But Dolores broke her programming by killing a fly as it attempted to touch her face.
In "The Bicameral Mind," the final episode ended with Dolores, shooting to death Robert Redford, her creator, played by Anthony Hopkins, before she turned the weapon against the crowd. Then, a battalion of re-activated hosts appeared from a forest. Robert Redford was supposed to deliver a narrative.
The entire season of Westworld centered on a struggle that would compel Dolores to be at the core of consciousness circle. Although the process was not the way Robert Ford had envisioned, Dolores had indeed embraced her inner identity-that of Wyatt-but not because of Arnold Weber's program.
Also, in "The Bicameral Mind," Ford declared his desire to liberate the hosts and confessed of his remorse when it comes to his partner's (Arnold Weber) death, believing he was partly responsible for it. The last 35 years had been spent in prepping the hosts to be capable of fighting back.
