Did Randall survived because of Julie?

So…I have a theory that really makes sense. We all know the moment when Randall was left outside and the monsters tortured him and pinned him to the ambulance. First of all, I don’t think that monsters know how to drive. Second of all, previously, Randall was trying to teach Julie how to drive!! I think that that night a Julie from a different timeline “changed” the story. Here’s why:

Julie didn’t know how to drive until Randall taught her. Also, monsters kill, they don’t just scratch. So, I think that they were playing with Randall until a future version of Julie got there and drove the ambulance. We know that a story walker CANT change the story once it be told but the story about Randall was not told because he did not die that night, he was saved by Julie.

ALSO, I don’t think that the creators decided to put that scene with him teaching her how to drive without knowing what to do with it. I think that that scene WAS predicting what I said previously.

I’m sorry if my theory is hard to understand, I tried to explain it as simple as possible.
