"Trompe L'Oeil"[]
Theresa Cullen has a secret meeting with Charlotte to discuss the failure of their plan to transmit data out of the park, revealing that they are working together to get Robert Ford removed from the park. The plan to transmit the data was meant to be a failsafe in the event that Ford wiped the Hosts' memories on his way out. They come up with a plan to demonstrate that the latest updates to the Hosts cause them to become violent, thus humiliating Ford and possibly getting him removed from the park.
The demonstration happens, using Clementine Pennyfeather and a male Host to show a glitch in the Hosts' programming which causes them to remember past experiences and react violently as a result. Charlotte and Theresa watch the demonstration with the board members, and point out the error in the Hosts' programming. Bernard Lowe takes the blame for allowing the introduction of faulty code, and Charlotte fires him.[1]
Bernard takes Theresa to the secret house hidden by Robert. Lowe is then revealed to be a host, as Robert comes into the secret lab. Robert enunciates the same words privately spoken by Charlotte Hale to Theresa about a "blood sacrifice", which brings to question whether Hale is a human or a host.
