oooooo! More evidence showing that Neil/Bae was in neverland – which is how he stayed so young.
This leads me to another thought. What if Bae ended up in our world, ran across Jefferson, told Jefferson his tale, Jefferson knew of the curse and what would cause it to break, then portal-hopped him to neverland, then brought him back while he was still a boy where he grew up and was the “proper” age when he met Emma.
