Legion: 11 Questions Left By The Weirdest Marvel TV Show Ever
8. So The Supporting Cast Are Definitely Real?
Seeing as David's damaged mind frequently altered his memories and his perception of reality, we quickly learned not to trust what we see on Legion. A common fan theory that grew around the show was that David's allies at Summerland were all figments of his imagination.
Much like the various personalities he possesses in the comics. In particular, it was thought that Syd wasn't real. For instance, during a scene in episode 1 she visits David in his bedroom - but she must have been hovering as we do not see her legs underneath the bed when she approaches.
Come the end of the season, though, and it seems pretty certain that each and every one of the Summerland team is an actual person, as we have seen them interacting with the world around them and more over and over. The twist that at least one of them is just a product of David's mind is such an irresistible idea, though, that I have a feeling it is still to come. But it wouldn't make sense at all, would it?
