At a Union Army outpost, the soldiers recognize Teddy as an accomplice in Wyatt's massacre of his unit. After recalling his complicity, Teddy escapes with the Man in Black by killing all of the soldiers. Sizemore is introduced by Theresa to Hale, a Board representative sent to observe park operations. Theresa ends her relationship with Bernard, who finds out that Ford has secretly been keeping a family of hosts. Elsie continues investigating the glitches and tells Bernard that Theresa is behind the espionage, and that the first generation hosts have been re-programmed by someone calling themselves Arnold. However, she is abducted by an unknown assailant. A child host kills his dog, telling Ford that Arnold told him to. Felix gives Maeve a tour of the company. She bends him and Sylvester to her will and convinces them to change her programming, setting her awareness rating to its maximum level while decreasing her loyalty.
This episode provides examples of:
- Alone with the Psycho: Despite being dumped by her earlier, Bernard decides to warn Theresa about the espionage, only for Elsie to ring and tell him that she's the one who's been activating the stray host.
- Butt-Monkey: Sizemore is Drowning My Sorrows and pours out his troubles to a pretty girl, mentioning the recent host malfunctions. The girl turns out to be the executive director of the board, and they're formally introduced after Sizemore decides to publicly urinate all over The Big Board.
- Call-Back: Maeve wakes up in bed in the same manner and camera shot that Dolores used to.
- The Cameo / Mythology Gag: When Bernard goes down to the abandoned sublevels, there's an out of focus shot of a host dressed in black who looks a lot like Yul Brynner's Gunslinger
from the original movie. - Conflicting Loyalty:
- Bernard finds himself in this position. Should he be loyal to his staff, his former mentor and friend, or his boss who's also his secret lover who's just ended their relationship?
- Theresa dumps Bernard, pointing out that their relationship could suggest a conflict of interest, given that Operations and Programming are supposed to keep tabs on each other.
- Death Is Cheap: Maeve taunts a client with a Teeny Weenie so he'll choke her to death during sex, so she can have another chat with Felix. Though she does insist that her pain levels be dialed down, so it won't hurt so much the next time.
- Evil Genius: Elsie calls Arnold this when searching the abandoned theater.
- Eye Scream: One host gets shot in the eye with a gatling gun.
- Fake Memories: Turns out the past of each host is only changed slightly for each new build, to avoid the work of writing a completely new program.
- Foreshadowing: When Maeve is "touring" the facility, the video says "Westworld: A Delos Destination," not "The Delos Destination," implying more "destinations" exist.
- Funny Background Event: The big cowboy who keeps deliberately bumping into guests as they arrive off the train does so to a man who draws his gun and shoots him. Maeve just keeps walking.
- Gatling Good: Teddy mows down an entire Union camp with a Gatling gun.
- Have You Told Anyone Else?: Played with; When Bernard asks this question, Elsie mentions that she considered that Bernard could be involved in the espionage, but feels he's been there too long and would have sold them out long before. However Elsie later crows over how she's going to take Theresa's position when she gets the chop over this, to someone who is (or was) in a Secret Relationship with her. Bernard is actually on the verge of telling Theresa when Elsie discovers she's also involved.
- Heroic BSoD: Literally; Maeve's program locks up when Felix shows that her every word is dictated by a program.
- Hypocrite: Sylvester threatens to report Felix when he thinks he's playing around with a host, but it turns out he's running his own covert pimping scheme.
- Idiot Ball: When Elsie is tasked with investigating a remote location for signs of corporate espionage, she goes completely alone and unarmed, seeming just so she doesn't need to worry about someone else taking the credit. It ends more or less as you expect.
- Kiss Me, I'm Virtual: Turns out Sylvester has a lucrative sideline pimping the hosts to the techs, by hacking their programs and wiping all traces afterwards. As it's similar to her own profession, Maeve doesn't take offense, but finds it useful blackmail material.
- Let's Get Dangerous!:
- Maeve threatens Sylvester with a scalpel, and forces him and Felix to alter her, making her less loyal, less receptive to pain, and much, much smarter.
- It's revealed that Teddy helped Wyatt with his original massacre. He escapes from his bonds and wipes out the Union camp virtually single-handed. The Man in Black is impressed by these Hidden Depths.
- Logic Bomb: Maeve suffers one when Felix hands her a tablet which is currently displaying her thought processes. Seeing her own thoughts being spelled out as she tries to voice them causes her to suffer a literal Heroic BSoD until Felix manages to snap her out of it.
- The Man Behind the Curtain: Maeve insists on taking a look 'upstairs', and sees the hosts being built, designed, and trained. She even sees herself in an advert for Westworld, acting in an entirely different build.
- Morality Dial: One of the attributes on the personality matrix is "Cruelty".
- Mugged for Disguise: Teddy and the Man in Black mug some Union soldiers to get past a Union checkpoint via Dressing as the Enemy. The Man in Black keeps his black Stetson instead of trading it for a Union army hat, but it's Teddy's history with the Union that gets them caught.
- Nostalgia Filter: Averted; Arnold created a host recreation of a happy childhood time as a gift to Ford, but he's changed the program so his father is a violent drunk like he apparently was in real life.
- Not Now, Kiddo: Played with; Bernard hangs up the first time Elsie tries to ring him, but she just calls again and tells him not to hang up because she's got something important to tell him.
- Platonic Prostitution: Turns out William isn't the only client who pays just to talk to Clementine.
- Right Behind Me followed by Right in Front of Me: Sizemore pisses on the digital map while insulting Theresa, who then appears behind him and introduces Sizemore to her boss.
- Robotic Reveal: When the young boy reveals himself to be host by opening up his face.
- "Second Law" My Ass!: Maeve gets Sylvester to dial down her Loyalty attribute and increase her intelligence.
- Three Laws-Compliant:
- Elsie has an Oh, Crap! reaction on discovering that someone has been tampering with the prime directives of the earlier model hosts, making it possible for them to injure people.
- When Maeve puts a scalpel to his throat, Sylvester says that she can't hurt him, but Maeve convinces him that Felix has rewritten her program. When Sylvester examines her attribute matrix, he discovers someone with high-level clearance has already adjusted her paranoia and self-preservation, explaining how she's able to threaten them in the first place.
- Tomato in the Mirror: Lampshaded; when Felix tries to convince Maeve she's Just a Machine with Fake Memories, she asks how does Felix know that he isn't one as well.
