History Recap / WestworldS04E07Metanoia

* SomethingOnlyTheyWouldSay: When Caleb starts attacking Frankie, thinking she was part of a trick sent by Hale, she gets him to stop by telling him about how he trained her and why he calls her Cookie.

* KillEmAll: By the end, the Man in Black has killed William, Hale, Maeve, and Bernard, and has begun a final game to end humanity and hosts alike.

** It is not explained why the destruction of sentient life on Earth is, according to Bernard, inevitable, and couldn't be thwarted by either destroying the Tower or ambushing the Man in Black before he could reach it. Or, after referring to her as a "weapon" in previous episodes, why it was necessary for Bernard's plan to send Maeve after Charlotte, who was no longer the main threat at this point, only for her to be shot.

* FaceHeelTurn: The Man in Black betrays Hale by shooting her in the head. He then forces everybody to fight each other to the death, throwing her transcendence plan out of the window.

* TheStarscream: The Man in Black is dismayed with Hale's transcendence plan. After chatting and killing William, he brings down Hale by killing her, and then takes over the Tower by reprogramming everybody into a deathmatch which he calls "survival of the fittest".

* BoomHeadshot: This is how the Man in Black kills Maeve, Hale, and Bernard. If he proves to have destroyed their control pearls, all three are likely dead for good.
* BroughtDownToNormal: William's HatePlague overrides Christina's narrative control, taking away her ability to manipulate humans. However, this leads into the following reveal, that she isn't really present in the world at all, and now no one but Teddy can see her.

* DoesThisRemindYouOfAnything: Christina, suffering a crisis of identity as well as overwhelming guilt and grief for the world she inadvertently created, tries to drown herself in the bathtub, but ultimately survives and awakens as Dolores in an almost literal death and resurrection via baptism.

* HumanityIsInfectious: Human William compares his memories inside Host William to a cancer, slowly taking over. From this, he reasons, it doesn't matter if he isn't released or even if Host William kills him, because Host William will ''be'' him.

* OutOfCharacterAlert: Bernard tries to leave Stubbs with a compliment, but Stubbs immediately suspects Bernard is deflecting because he's making a conscious effort not to be an ass. Bernard admits that Stubbs is going to die when Stubbs realizes the implications of Bernard's kindness.

* TheReveal: Christina and Teddy are not in the physical world where the rest of the main characters are.

* GoOutWithASmile: Right after The Man in Black stabs William, he smiles as he dies from blood loss.

* IrrevocableOrder: William's HatePlague command has the additional effect of destroying the tower, so it can't be reversed.

** Hale and Bernard have their brain pearls shot out by Host William just before he sets the world on a path to complete destruction. With no backups and no one left to restore them, they are permanently gone. Hale's case is ultimately a subversion, as she gets revived by a pair of drone Hosts in the final episode.
** Played with for Maeve, who is also killed by Host William in a shot that destroys her brain pearl, but since she is a copy of the one who entered the Sublime her identity is technically still alive.
