The HBO Max smash hit TV show Westworld is returning for Season 4, so it's time to remember what our favorite characters have been doing for three previous seasons. William (Jimmi Simpson), better known as the Man in Black (Ed Harris), has a tumultuous journey of self-discovery, grief, and rage throughout the show.

In the first season, Dr. Robert Ford (Anthony Hopkins) implements a new "Reverie" update that causes some Hosts, including farmer's daughter Dolores Abernathy (Evan Rachel Wood) and local madam Maeve Millay (Thandiwe Newton), to gain consciousness of their previously-erased memories and become sentient.
