Final week, Maeve (Thandiwe Newton) and Caleb (Aaron Paul) had been coping with a variety of issues after breaking into the latest Delos park, full with a «Westworld bloodbath» Easter egg narrative for guests. They managed to get down into the basement ranges of the park and found the parasite inside flies that Hale (Tessa Thompson) is utilizing to start to regulate people, however then Caleb was swarmed by mentioned flies. Episode 4 begins with a flashback to the top of season 3, when Maeve and Caleb blew up the supercomputer Rehoboam, and Caleb was shot. He tells Maeve that he is unhappy he’ll by no means know life after the conflict, he’ll by no means know freedom, and she or he hacks his mind implants to indicate him reminiscences of her personal freedom together with her daughter within the fields.
The flashback is revealed to be a dream, as Caleb involves and Hale is standing over him. «Wakey wakey,» she taunts, earlier than informing him that she made him her pet, and intends on doing that to all of humanity, utilizing the parasite. Caleb asks about his spouse and daughter and Hale informs him that they are «nonetheless someplace on the market alive,» however she does not care as a result of quickly she’ll have everybody beneath her management. Each customer to the park will probably be a provider of the parasite, and they’re going to unfold it among the many human inhabitants till Hale has the power to regulate anybody utilizing these bizarre sound waves.
In the meantime, Maeve and host William have slightly combat, however she will get away and manages to achieve management of the sound machine, overwhelming it and piercing the ears of the hosts. It will definitely shatters all the glass within the underground lab, giving Caleb an opportunity to get away. He grabs a shard and holds it to Hale’s throat, then Maeve exhibits up and so they begin heading for the door. They handcuff Hale, however she manages to get the sound machine working once more to some extent and all the hosts round them begin going berserk. Maeve stays calm as a result of the hosts are all copies of Westworld hosts, and she or he’s «lived this a thousand instances.» Issues appear to be going alright for the duo, then Hale manages to get into Caleb’s mind a bit and orders him to select up a gun and intention it at Maeve. He fights her sufficient to not shoot, but it surely provides a random host alternative to stab poor Caleb. Maeve rescues him however simply barely, and so they drive off into the desert in an outdated truck stuffed with moonshine.
Caleb is shedding a variety of blood, and he asks Maeve if she’s going to desert him once more. She explains that she did not abandon him after Rehoboam, however that she sat at his hospital bedside for weeks. She understood mortality for the primary time, and it scared her. She realized that to ensure that Caleb to be free and pleased, she must take away herself from the image fully:
«Our sorts are locked in a perpetual battle. I needed you to do greater than combat to outlive. I needed you to have one thing to combat for. I had already identified the love of a daughter, and I deliberate on spending eternity holding it expensive. I knew that if I stayed put, no hurt would come to you. You deserved to have one thing actual to carry onto. That is why I left. And it could have been superb besides in the future I acquired curious. So I reached out by way of the grid to seek out you, and…»
And, Maeve now is aware of, that is how Hale discovered each of them. If she had by no means reached out, Caleb and his household would nonetheless be secure. That has to weigh closely on her, however they should hold transferring. They head to a building web site and sadly, William is ready. (That man simply won’t die.) Maeve arms Caleb her gun and he warns her to not belief him with it, however she laughs and says «I simply did.» He calls his workforce of mercenaries to come back choose them up and finds out that his spouse and daughter are secure. Hale begins entering into his head and forces him to intention the gun at Maeve, however then he turns and shoots William on the final second. The victory is short-lived, nonetheless, as William shoots Maeve from his spot mendacity on the bottom after which will get up as soon as extra. Maeve walks over to William and wraps her arms round him, telling him that within the park she discovered to «at all times insist on mutual satisfaction.» She has armed a bunch of explosives within the floor, and units them off, killing each her and William.
That is the place issues begin getting wild. We barely have an opportunity to grieve Maeve, top-of-the-line characters within the collection, and Hale begins questioning Caleb about his reminiscences. We watch as Hale’s males arrive and Caleb is shot repeatedly. Hale explains that the human Caleb died that day, and that the Caleb we’re watching is a bunch. Not only a host, however the 278th model of Caleb that Hale has made. «It is a part of an interview, to determine a baseline. Constancy.» We see that Caleb and Hale are in one of many rooms from the primary two seasons the place Dolores (Evan Rachel Wooden) and her handlers would work together. It seems that Hale’s parasite did not work on adults very effectively, so she needed to await the subsequent era to change into adults, all contaminated with the parasite as youngsters. It has been 23 years since Caleb died within the park. He escapes the room and is within the constructing the place Christina (additionally Evan Rachel Wooden) works. He runs exterior and sees the Tower, then Hale makes everybody cease besides her and Caleb. He realizes what meaning, that the world has been misplaced to Hale, and it has some actually terrifying ramifications.
