Legion S02E06- Chapter 14 UNspoiled! Legion

Well listeners, I know I say pretty much every time there's a new episode of Legion that it was "weird", but this time I mean it in a slightly different way than usual. I mean yes, the episode is plenty weird, don't get me wrong, but instead of it just being the content, I'm also a little puzzled by the timing. Doesn't this seem like a strange point in the story to have an episode like this?
My running theory is that this episode is meant to serve as a reminder to the audience about the importance of David's sister Amy, since we haven't seen her on the show since last season. It didn't really occur to me to wonder what was going on with her yet, because frankly there was a lot of other shit we didn't know and that seemed like the least of our concerns. But every timeline where Amy isn't a force in David's life has him living on the street and maybe strung out on meth (well except for the one where he's a drone at a desk watching a rat sing and dance). So I feel like that's what we're supposed to be getting from this, is a reminder that she's been the only person looking out for him this whole time.
I feel like there were better, more effective ways of showing us that, though, so I'm not positive that I even buy into my own premise. I am fascinated by these alternative realities, though, and naturally have a lot of questions. Will these timelines play into anything later on? We end the episode, as usual, with more questions than answers.
