Will Captain Morales die in Miles’ world, and what happens if he doesn’t?

So, with the real Miles now in another dimension, it leaves the door wide open for what Miguel thinks has to happen, to actually happen. For Miles’ dad to die. But, if Spider-Man isn’t there to witness is, does it have the same impact? Is Spider-Man’s absence an equally large break to the canon? Plus, even if Miles gets back and saves him, what happens then? Will the universe collapse? We have no idea but these are questions that will be central to the final film. (Plus that whole thing with Gwen’s dad we mentioned a few pages back.)
