Legion opens its Third Season not with David (Dan Stevens) but with the introduction of a time traveler who we will come to know as Switch (Lauren Tsai). Going even more psychedelic and strange in the first 20 minutes, "Chapter 20" oddly becomes more linear once its storyline becomes less so as Switch travels back in time to save David's life and the singular point-of-view splits from her to several other characters. Most of the first-half of the episode involves Switch following clues which lead to a hippie commune and an eventual meeting with David, a man she never completely trusts. The sudden attack by Division 3 on David's compound not only leads to Switch traveling back in time in an attempt to save his life but also forces her to chose a side in a war that, until now, she didn't even know existed.
