Headcanon: Hook and snow are the same person from different realms. And considering that realm jumping is possible and killian has done it many times and the war he was getting the thing for was NOT the ogre war. It is my headcanon.

Do you mean realms or dimensions? Because realm jumping is indeed possible but I think you mean dimensions.

Either or. I mean, who knows exactly how powerful the beans are. Considering they can take people to places where the laws of the universe are different (land with magic vs land without magic vs land where magic works differently)
It’s clear that some realms exist in an entirely different universe like our world vs the enchanted forest

I’m thinking realms and dimensions are different though. Because like our world is a realm, Enchanted Forest is a realm, Neverland is a realm, but then the page showing Regina having her happy ending with Robin isn’t. It’s a different reality entirely.

I think what you mean is universe, not dimension. They all happen in the third dimension. they all exist in the same deminsion. But some realms are in different universes. Like our universe is not the same one that has enchanted forest and arendelle (Which are in the same universe as each other) Neverland is in a separate universe. Hook came from another universe. Regina and hook would be an alternate timeline just like how emma and hook being in the book when snow and david meet is an alternate timeline as the one where they weren’t.

Hook didn’t come from a different universe though he came from The Enchanted Forest and then went to Neverland.

Did he? I thought the war he was getting the poison for was a different war than the ogre war. They were fighting people, not ogres. And he became a pirate and traveled across the realms to be pirate and made his way to the enchanted forests realm.

It was different than the ogres war but it was still Enchanted Forest. And he’s been alive for like 300+ years, or at least for as long as Rumple has been The Dark One. So yeah.
