Lee Sizemore runs the Narrative dept. at Westworld. His storylines consistently delight and/or terrify the guests; his temperament consistently grates on his colleagues.
During discussions with Dr. Ford and Bernard, he opposes the idea of making the Hosts more lifelike. He tells them: "But does anyone truly want that? Do you want to think that your husband is really fucking that beautiful girl or that you really just shot someone? This place works because the guests know the hosts aren't real."
Lee performs as he outlines his newest narrative, "Odyssey on Red River". He speaks about how wonderful it will be. Dr. Ford watches, as are Theresa and Bernard. Ford's reply to Lee's idea is simply "No, I don't think so." Ford doesn't understand the point and humiliates Sizemore in front of everyone.
Lee has taken "sick leave" after his "Odyssey on Red River" narrative is rejected. He's resigned himself to getting wasted while sitting poolside. There he meets an attractive woman who he tries and fails to flirt with. After having been cut off from the bar, Lee steals a bottle of alcohol and proceeds to pee all over the park operations control room. There he is introduced to Charlotte Hale by Theresa Cullen, who turns out to be one of the Board members of Delos Destinations, Inc.
Charlotte interrupts Lee while he programmes a host. He apologises for their awkward first meeting, and says that he has heard about Theresa's death. Charlotte comments that her death is a loss to the company, and Lee states that there's a rumour going around that says Theresa wasn't the loyal worker everyone thinks. Charlotte defends her, saying that she died doing something important for the company, but refuses to answer Lee's questions about the nature of her work.
In his annoyance he boasts that Ford asked him to secretly programme a villian for his new narrative, which Charlotte scoffs at, saying that he is only doing busy work. She tells him Ford would never trust him with a key character for one of his narratives, and offers him a job working with her.
That night the two make their way down to Cold Storage and look through the decommissioned Hosts. Charlotte selects Peter Abernathy, and reveals her plan to upload all the park's code onto his server, something that can only be done with a Host that has no stored information. She tells Lee to programme Peter with a personality convincing enough that he can escape the park, and leaves him to it.
