Nick Branson wrote: In Homecoming, WRumple said "wishes can be powerful things" meaning WRealm was created by the wish and hasn't existed before which means it changed the past and its interactions with other realms. I have an answer I've posted in previous discussions. I'm using WishCruella and WishPan as examples:

From a headcanon perspective (likely actual canon based on what we've seen), it can be argued that the WR counterparts only have the memories of the "real" EF characters.

EF and its everybody present in it (natives and non-natives alike) were copied at a specific point in the past during the Charmings' war to take back the kingdom (I call it the "origin"). WR didn't technically start to exist before that moment, anything that "happened" before then (events, character births and deaths, etc.) is arguably the result of memories being copied over as well. They never actually experienced pre-origin events.

e.g. WishHook never went to Neverland before the First Curse, he only has the memories of "real" Hook who did. His post-origin interactions with WishQueen and visit to NEF for the flower did actually happen though. No changing the past, just new interactions and events post-origin in WR.
