The finale opens with a street littered with corpses. Civilians kill each other without mercy or ceremony, turning once peaceful city blocks into veritable war zones. Fleeting guest castings come and go. (Hello, Stephen Ogg!) A young marksman takes out a handful of these murderous pedestrians before William kills him. The Man in Black has plunged the world into chaos and returned to his element. Back at the tower, Hale’s faceless subordinates retrieve and revive her. “Make me stronger,” he tells them. But, “Leave my marks. I want to remember my past.” Her voice is quiet but strong, firm with determination. She climbs the tower to see William’s work for herself. There, he finds the message Bernard recorded on a tablet seconds before William shot him. It turns out that Bernard had left the message specifically for Hale.

At her apartment, Christina is upset by the revelation that she is not real. Teddy channels Descartes with an “I think, therefore I am” platitude, but Christina is overcome with confusion and grief. She suddenly realizes that she was never alone because the part of her that created this world created her friends to keep her happy. This means that Maya (who we’ve been wondering about) was a figment of Christina’s mind, a construct she dreamed up so she wouldn’t feel alone. She says she has to wake up and she and Teddy kiss on her balcony. An enraged Hale remotely interrupts their makeup by pulling out the hologram of New York. The buildings around Teddy and Christina begin to flicker. Teddy realizes that Hale is coming for them, but Christina declares that she won’t give up her world without a fight. Hale destroys the hologram but keeps stomping on, eventually cracking the floor of the tower and revealing what she’s really after – one of Dolores’ pearls. A weakened Caleb, an injured Frankie and Stubbs stop to rest. Stubbs worries they won’t make it out of town, while Caleb remains determined to do right by his daughter. They take refuge in a convenience store, where Frankie tells Caleb that Wade died of cancer years ago. Caleb’s body lets him down, Frankie observes, but he won’t explain himself to her. Hale visits OG William in prison. Upon discovering his body, Hale remarks, “I finally got what you wanted.” Clementine emerges from the shadows and after a brief back and forth, convinces Hale to free her. Hale sends a handful of hosts after William’s delusional copy in an attempt to slow him down. William kills his pursuers (Hey, Jonathan Tucker!) and communicates with Hale using a pair of glasses that project her onto a nearby tree stump. Here we learn William’s new goal: to destroy Sublime. So he sets off for the Hoover Dam on horseback. In her reality, Christina spots Maya sitting on a bench under a large tree. It’s a quiet scene in which Maya tells Christina that she can choose which parts of the world she sees. He speaks of an “ancient order” and a “deep peace”, referring of course to the natural world and its beauty. Clementine and an armed civilian take turns attacking Caleb, Frankie, and Stubbs at the convenience store. Clementine shoots the unnamed assailant before brutally killing Stubbs. She then briefly engages Caleb in a wild fight before Frankie shoots her in the head with the one bullet she apparently has left. William arrives at the Hoover Dam and begins his attack on the Supreme. Hale intercepts and confronts him, saying that William has been “tainted” by the now-dead man. A fierce battle ensues, taking the two out and around the barrier as the door to the Sublime pulses… William gains the upper hand and chases Hale into a nearby tunnel, triggering a flashback in which we learn that Bernard’s final message is actually a set of instructions. We remember how Bernard left a gun in the same tunnel (for Hale to use at this very moment), and Hale actually grabs the gun, shoots William, and rips the control unit out of his head. He grinds his pearl into dust as he walks away. Caleb and Frankie meet Odina at the docks, where Caleb tells Frankie the truth: that her father died a long time ago and that this body is dying. They say goodbye in tears. Using Dolores’ pearl, Hale transports Christina, Teddy and their world to the Sublime. There, Christina realizes that she was able to bring Teddy back because Dolores loved him so deeply. Before Teddy gets too freaked out that he isn’t there, Christina wakes up in her bed. At first, it’s Teddy sitting at the foot of her bed. But she transforms into Dolores as she looked and sounded in Westworld all those years ago. He tells Christina that they are reflections of their creators and that humans will disappear. “Que Sera, Sera” ends with Christina walking through the burning streets of New York as Dolores, while an abused Hale takes off her meat suit, removes the control unit from her head and grinds it into her hand. The final moments see Christina using Sublime to return to Westworld, where in a little narration she talks about her hope that things will be different now. And that’s the end of Westworld Season 4! That sure felt like a series finale, didn’t it? (The EPs tell Deadline that no decision has been made yet.) Let us know what you think of this hit of a closer.
