The Latest "Westworld" Reveal Shows It's No "Game of Thrones"

As the deviously puzzling first half of HBO's "Westworld" has unfolded, sleuths on fan sites and reddit threads have spun elaborate theories about what is really going on in the futuristic, Wild West-themed amusement park of the title. We know that the park is an adult playground where human "guests" can carry out their most sadistic fantasies on the bodies of the grounds' life-like robot "hosts." We know that each day, after being raped, murdered, and otherwise violated for the pleasures of their guests, the robots are refurbished by Westworld staff, their memories wiped clean--but that, by a glitch in the system (or by some secret design), hosts like the obedient and good-hearted Dolores (Evan Rachel Wood) and the sharp-tongued bordello owner Maeve (Thandie Newton) are beginning to piece together their traumatic pasts. But there are so many essential things that we don't yet understand. Who was Arnold, the park's mysterious co-creator, who died somewhere within Westworld's borders and whose ghost seems to be haunting his android creations?
