Westworld: 31 WTF Moments From Season 1
5. Dolores Kills Arnold, Is Wyatt
Going back to the beginning (of the park, not the show) and we really start to see how everything came together.
After multiple clips of a similar scene, we see how it all plays out, and the formation of the new Wyatt storyline.
The crux of it is that Dolores kills Bernard/Arnold, and with that becomes Wyatt, the new villain of Westworld. Delores' sweet exterior was masking this dangerous interior, and it's the beggining of her journey. But also the end. It's a loop.
