Jacob Magellan Portman Timeline & Summary

Little Jacob wants to be an explorer just like his Grandpa Abe, who tells him stories of peculiar children and eternal life in a time where every day is the same…
Until Jacob decides Grandpa is a stinky ol' liar.
When Jacob is a teenager, he goes to check on his grandpa and finds him dying in the woods.
Grandpa dies in Jacob's arms, but utters some cryptic last words with his final breath.
Jacob sees what killed his grandpa in the woods: a tentacle-mouthed monster.
In therapy (that would send anyone to therapy), his psychiatrist suggests Jacob go to the island where Grandpa is raised.
Jacob does, and discovers Miss Peregrine's home for peculiar children, which is stuck in a time loop on September 3, 1940.
There, Jacob starts falling for Emma Bloom, his grandpa's ex-girlfriend, who is sixteen going on ninety, thanks to the time-stopping powers of the time loop.
They learn about an evil plot to kidnap ymbrynes—people like Miss Peregrine, the headmistress, who can manipulate time—so the hollowgast can achieve immortality.
Jacob's psychiatrist is a wight, a monster helping the hollowgast, and Jacob inadvertently leads him to Miss Peregrine.
When Peregrine is birdnapped, Jacob and his friends pursue the wight and rescue her.
Unfortunately, she can't return to human form. Jacob realizes he must stay in the time loop to find a way to heal her, so he tells his dad goodbye, and returns to live in the past.
