Ed Harris's character in Westworld is a black hat, in every sense of the word. He's both an evil cowboy and is trying to hack Westworld for some nefarious purpose.
That's 'hack' in a literal sense, as in the first episode he set about dismantling the theme park in the most brutal way possible. Like another man in black once said, he killed a Host just to read the map on the inside of his skull.
But who exactly is he? Is he a rogue robot? Is he human? And how does he connect to the original Westworld movie, and the original gunslinger Yul Brynner?
We looked over some of the theories, but let us know your own!
