Season Two


James Delos is first seen visiting Sweetwater early in the the park's history. With the Hosts, including Dolores Abernathy and Teddy Flood frozen around them, James and William have a conversation about the potential of the park. William tells him that if James can't see the potential for data-mining of the guests, then he is not as good a businessman as he has heard. James likes William's courage at challenging him, and invites him to tell him what kind of ideas he has in mind.

Later, James is at his retirement party, having seemingly passed over Logan for control of the company in favor of William. James mentions that he does not have much time left and coughs repeatedly, indicating that he is ill.

"The Riddle of the Sphinx"

We see James in a stylish apartment, and he is notified he has a guest. It turns out to be William, and James asks when he will be able to get out of his confinement. William tells him that they are monitoring him, and need to do some tests on him to determine if he can be released. This scene repeats several times, including when William is the age of the Man in Black, and we find out that James is a host who they have implanted the memories of James as a test. Host James appears to be lasting a number of days working fine, but each time he winds up breaking down and the Westworld staff have to burn down the apartment and start over again.

Bernard and Elsie are in a secret lab in Sector 12 when Elsie breaks in to a mostly destroyed room where host James is barely functioning after having been left alone for so long. They discover the body of the technician who presumably was supposed to incinerate him after watching his degradation on William's orders for a few days. Bernard winds up scuffling with host James, and after the fight Elsie incinerates him to put him out of his misery.
