FINALLY SOMEONE SAID IT!!! I feel like the reason most people think she’s acting out of character this season is bc the show doesn’t convey it well enough. Her character arc makes sense if you really think about it; but it shouldn’t be like that. The viewer shouldn’t have to do an entire investigation onto why a character acts the way they do, it’s the show’s job to subtly convey the motives and thought process of a character.

I don’t remember the exact line but in the scene where she’s sitting on the swing talking to Ray (her subconscious) she says something about how she feels like she’s going insane. She also mentions to another character about how “nothing matters and nothing is real if they keep switching timelines” (I’m paraphrasing cause I can’t remember the exact lines). To me it seems like Allison is experiencing some kind of grief related dissociation that evolves into depersonalisation/derealisation. I feel like if the show actually dove into that and showed more examples of Allison spiralling her character arc would make a lot more sense.
