OK here is a thought.
We know Bae came to our world. So what if somehow Hook found out and trying to enact his revenge against Rumple,brought Bae from our world to Neverland. Bae spent most of the last 300 years trying to get back to Rumple and ended up making it only back to our world.
That would make Bae, Peter Pan and would set up a tie between Bae and Hook.
