One of the more interesting side characters in Season 1 was Peter Abernathy, as played by Louis Herthum, as his host was not only Delores’ father but also the mysterious Professor and perhaps more.
Herthum was upped to a series regular for Season 2, and he shared his thoughts about Peter’s future.
Lots of TV shows feature twists where one character is revealed to be someone else entirely, but nothing out there does it quite like Westworld, thanks to the HBO drama’s large population of android hosts with malleable memories and personalities.
