I was just thinking, what if Neverland is like Jefferson’s Hat? We know the rules for The Hat are that the number of people that come in must be the same as the number of people that come out. What if when Rumple came in, Bae found this out and was able to leave. And when Regina came in (based on what JMo said), Hook was able to leave. I mean, we know ONLY Hook came through. This could be a great explanation as to why.
That wouldn’t work because otherwise how would Rumple and Regina have left Neverland?
