When we left Westworld at the end of Season 1, there was quite a bit of chaos.
Although the show’s producers previously stated Westworld would not pick up right where it left off, it seems as if chaos will still be running supreme in the parks when Season 2 returns.
He had set off a sequence of programming to prepare the hosts to fight back and essentially set them free at the end of Season 1, with Dolores first killing Ford and then setting off a rampage in the park.
The Man in Black had revealed himself to be an older version of William, and Ford had revealed to Bernard and Dolores that he had regretted Arnold dying and had come to respect and understand his viewpoints in relation to the hosts.
