In the movie "Miss Peregrine's Home for Peculiar Children", Mr. Barron kidnaps Miss Peregrine in order to use her in his immortality experiment. With Miss Peregrine gone, the time loop she created in September 1943 collapses, stranding Jake and the other kids in 1943. So to rescue Miss Peregrine, they take a ship to Blackpool, where Miss Avicet's loop in January 2016 is located. While aboard the ship, Emma says this to Jake:
Jake, you know what this means don't you? ... We have to get to our own time but you don't. You can continue to live in 2016... If we kill Barron, he'll be gone but time will carry on. He won't go to Florida, Abe won't die, and you can go home."
My question is, how would killing Barron save the life of Jake's grandfather Abe? Abe died in July 2016, so theoretically killing a version of Barron from before then would prevent Abe's death. But that's not what happens; in Blackpool Barron speaks about Abe's death:
I tracked Abe Portman for months. All I needed was a few minutes to get the location of Miss Peregrine's loop from him. But no, Mathus couldn't wait. And instead, I had to masquerade as a psychiatrist for three weeks in Florida.
So if Barron has already participated in the Florida events, how will killing Bareon mean that "he won't go to Florida [and] Abe won't die"?
Is it supposed to be that if you die within a time loop you get erased from the timeline or something? This is mighty peculiar, no pun intended.
