Another weird thing that I need to double check, at the end of the episode before last (episode 6). Dolores, Teddy, and Lawrence are on the train. Lawrence has all the explosives in a big crates, which have the 'maze' symbol on top. Lawrence and Teddy are on one end of the crate (after talking, they're about to start drinking), and Dolores is on the other end and starts to stare at the maze. Then the camera changes to behind Dolores, so she is in the foreground with the crate in the background, and Lawrence and Teddy should be on the other side. But no one is there.
Presumably, they could have gone to a different car, but the editing makes it seem like they just disappear, as if they are only part of Dolores' imagination.
