Laura realises something is strange when her daughter Sophie wakes up in a different pair of pyjamas to the ones she went to bed in, although Sophie does not know why and Anita, their synth, denies that she took Sophie outside.

Mattie is attempting to tamper with the code of a synth, but this fails and the school that owns the synth is alerted. They suspect Mattie and talk with her mother, Laura, but have no evidence. Laura takes Mattie shopping and she admits it was her; they both discuss their dislike of and apprehension towards synths.

Leo finds Silas and learns that Anita has been given a new personality, but he is unable to discover where Anita is. Leo narrowly escapes after things become violent, but is injured in the process. Max helps him along to a public toilet and is able to restart an unconscious Leo by using wires from the lights. Meanwhile, Silas is arrested for tampering with synths. George Millican tells his synth Odi to hide, while his care worker forces a new synth named Vera upon him. George dislikes Vera, but mutters that he was involved in creating her as parts of his original designs are still implemented in synths today.

Niska works at a synth brothel and after a client asks her to act young and scared. Niska, however, refuses to which the man throttles her. Enraged by his twisted fantasy and threatening behavior, the renegade synthetic then strangles the man to death in self-defense, and removes the anti-theft chip from her neck, while leaving the brothel, threatening the clients if they said anything about her leaving the brothel.

Toby goes downstairs in the middle of the night to get water, and alerts Anita whilst she is charging, to which he asks for her to pretend he isn't there. But he tries to lay a hand on her breast, Anita warns him that inappropriate interaction would be reported to his parents as the primary users. Regretful, Toby requests Anita not to mention the incident to his parents.

Next morning, Mattie notices Anita does not transfer data with other synths and Laura makes a phone call to a help desk. After Anita cuddles Sophie without a parent's express permission, Laura announces that she is being returned and tells her children to say goodbye to Anita. When told she is going back, Anita smiles slightly.^[1]

Club gave the episode a B+, saying that George's storyline "digs the deepest" and that "Humans is approaching medical drama territory".^[6]
