People’re talking about how Dylan doesn’t seem to understand that her actions are changing the course of the story, but like?? I wouldn’t fault her for that?? Because she can’t know for sure whether or not events are locked into place, unlike us, who are familiar with this format. She’s only fighting for as much as she dares to, given the circumstances. She knows that Cedric’s first wife is destined to die, so she doesn’t want to take any chances and go down that one terrifying route when she and Emily could live out their lives in a different way.
Working within the nebulous confines of some cosmic narrative can be risky. She supports the future romance between Cedric and the FL and wants it to happen for them. All she’s asking for is her family’s safety and autonomy; AKA severing herself from the story, period.
