Yes. We know this because A. Baelfire was still Henry’s father (even though his name shouldn’t technically be Henry, since Regina never adopted him), and B. Nook was already an old man, when Emma and Regina first met him, but he was young, when he had Alice.
Yet all that happened once the wish was made so everything before it would be false memories. That is the problem. The whole thing did not exist until it was wished. So it started as Nook being old, fat, and drunk. It started when Henry was a young adult. This is why none of this makes any sense. To make sense you have to assume that the wish realm was always there and then if Nook was in Neverland why didn’t real Hook ever see him, why wasn’t there any confusion from the other characters that there were two Hooks hanging around. This why the whole Wish Realm thing should have never been brought back up.
He was in Wish!Neverland. EF2 has a different rate of passage of time. Again, I bring up my Dark Realm theory.
Since the writers decided to make the Wish Realm a real realm, as opposed to only coming into existence when the wish was made last season, it would seem to be an alternate universe realm instead of a newly created one. So yes, there would be a Wish Neverland and everything.
