I read a theory that the car will push Hook over the town line. What if it’s his memories, not Belles, that we should worry about? It would make sense from a storytelling point of view. How else are Rumple and Hook going to peacefully coexist now that the conflict has come to a violent head? And we know Colin Odonague is sticking around, sothey must somehow coexist. I hope it doesn’t happen though. I don’t want Hook to become less hook.
But if the car is coming into town when it hits Hook, then it’d just push him further away from the line, and not over it, right? Unless he rolls over it when he falls off the car? But like EQ says in the previous post, I doubt the line would affect Hook the same way anyway, given that he was shielded from the curse.
