Westworld
Jimmi Simpson as William in a scene from “Westworld.” During the Season 1 finale, it was finally revealed that he grew up to become the mysterious Man in Black played by Ed Harris. HBO

The season finale of “Westworld” Season 1 is truly heartbreaking. It was finally confirmed that the show has been featuring multiple timelines, and Jimmi Simpson’s idealistic, kind-hearted William will eventually grow up to be the brutal and sadistic Man in Black played by Ed Harris.

It was a reveal many eagle-eyed fans saw coming, but Simpson told Vanity Fair that he wasn’t as receptive as them.

It was only when their make-up artist asked Simpson to change the shape of his eyebrows that he started to become suspicious. “I started thinking the one reason was to make me look like someone else, and then I cycled through the Rolodex of the main players. There’s only one that really fit my look and dialect,” he said.

Harris has already confirmed to BBC Radio 4 that he will return next season as the Man in Black/William. But unfortunately, fans have seen the last of Simpson’s young William. “My William has served his purpose. As of now, I’ll be done at the end of Season 1,” he said.

Meanwhile, Simpson told The Hollywood Reporter that it was leading lady Evan Rachel Wood, who plays Dolores Abernathy, who was closest to the truth about William’s real identity. “Evan was easily the sharpest of all of us. She has an amazing mind,” he said. “She did bring up that William may be the Man in Black I think as early as episode three or four, right around the time that I knew. We were so fallen for William and Dolores at that moment that she said, ‘Well, that couldn't be the case, because of us.’ And it evaporated from her consciousness.”

Simpson said they continued playing the entire season like William will not become the Man in Black, so they were able to maintain Dolores and William’s innocence. “We played the entire thing as if it wasn't the case. She was bummed out after the reveal, as we all were, on some level,” he said.

“Westworld” Season 2 will return to HBO on 2018.
