If people come back wrong, then whatever is left of original Rumpel wouldn’t want that for Bae. He might be trying instead to be worthy of going where he thinks Bae is now.
Yes, I see what you’re saying. The big problem is that nothing has been said–explicitly–that Rumple came back wrong. It’s actually just a fan theory that Rumple fans have been using to try and rationalize Rumple’s current behavior.
Blue Fairy came back fine. Ana in WL came back fine (2x). Rumple coming back wrong would be a highly interesting story but the writers haven’t given anything definitive about if he did come back wrong–and it’s unlikely that they will given that A and E like move quite rapidly past their former arcs and almost never touch on them again.
