Hear me out: what if Julie is accidentally a villain?
Clickbait title, but legit topic. Actually hear me out, lol
Storywalking is real (as far as we know, that is, not just happening in Julie's head) but the past seems to be fixed. Meaning that (based on Julie's experience with Jim's death) everything involving storywalking to the past has already happened, and is a part of the present version of Fromland. We'll call this a fixed timeline, as opposed to the branching timelines of a multiverse.
If that's true, then anyone who has tried to change the past in Fromland has already failed because we can see in the present day that everything is awful. And Julie is currently trying to make those changes, which means she's destined to fail. We already saw her fail.
This is the fun part, though: what if she fails worse than just helplessly watching her dad die in front of her? What if, in using her powers without real consideration or understanding, she messes up SO badly that it's contributed to the current state of Fromland? What if, in her storywalking, she accidentally disrupts Tabitha and Jade's original souls from saving the children the first time around? Or prevents someone from stopping the ritual, or any of a million other chaos-theory, butterfly-effect sort of scenarios where a tiny action has a huge ripple effect. Distracting someone at the wrong time. Maybe even killing someone helpful, like she once (pretend) killed Norman.
I know this sounds like wild speculation, but if we go back and really look at the first interaction between the Matthews' family from episode one (which the writers have said is important), Julie is the one who kills Norman, and Tabitha is the one who brings him back.
There's a clear parallel here: Julie, in the past, breaks something, and Tabitha afterwards is the one to fix it. It aligns *perfectly* with the way the show has been building toward things, with Tabitha being sort of set up as the one who'll save the children, and it would be really clever foreshadowing from ep 1.
Even from a storytelling perspective, it would be a great way to show us what happened back in the sacrificing-the-children day without making us sit through a big flashback.
For what it's worth, on a scale of 1-10 in terms of likeliness to be real, I'll give this theory a 5. I think there's some solid in-story context to back this up and I think I'd be quite pleased if they went in this direction. That said, the evidence is mostly circumstantial and there's no *real* proof yet that they'll do anything like that. But it sure would be a great emotional payoff for Julie's storywalking plot arc, and would be the sort of kick in the gut (of guilt and shame) that she really needs as a character in order to get over herself.
