He is not Captain Hook.
His name is Jonathan Stuart, and he’s just an ornery post-alcoholic bookstore owner from Pasadena with a mania for fencing and a bad habit of disappointing his girlfriend. He doesn’t want to be in the Neverland, impossibly trapped aboard the Jolly Roger with a horde of greedy stinking pirates. He was tricked there by Peter Pan.
Pan happily invites children to come to his wondrous magical island, but he has to trick adults. No adult in their right mind would go willingly. Adults, you see, don’t have a very good time in the Neverland. The fairies and mermaids are against them. The island itself is against them. Most of all, Peter Pan is against them.
In particular, Peter Pan is against Jonathan Stuart. Why? Jonathan had better figure that out, and he’d better do it fast before his mutating memories insist that, not only does he indeed belong in this nightmarish hell of bloodthirsty children, ticking crocodiles and vengeful boy gods, but he’s never existed anyplace else.
So you see, he’s definitely not Captain Hook.
Well, not yet.
