The Man in Black is after the deepest level of the game in Westworld, but what does he hope to find there? His bizarre, seemingly villainous fixation with a mysterious map -- what looks like a petroglyph carved into a Host's skull -- is one of the most intriguing elements of HBO's smart new sci-fi show thus far.
The second episode of Westworld, "Chestnut," furthers Ed Harris' character's fixation on the "game" at the center of the theme park. It leads him to Clifton Collins Jr.'s Host character Lawrence, who he believes is the next piece of the puzzle. Tossing him Kissy's skull, he explained of the map, "It's the maze, the deepest level of this game. You're going to help me find the entrance."
