My theory (and sorry if this has been said before, and careful with spoilers because I know that mega spoiler pics of the finale have been leaked but I haven’t seen them!) is that Nealfire was the ORIGINAL Peter Pan. He’s certainly been around long enough. I think Tinker Bell probably helped him get out of NL before the curse hit. The lost boys, like everyone else, were cursed and sent to Storybrooke. Now that they’re awake, they want their Pan back, but get angry when they find out he grew up. But learning that he has a son, they decide to kidnap Henry to NL to make him the new Pan. I don’t think Henry would ever run away to NL alone, he loves his family too much and wants to fix it. But I do think that once he gets to NL he’s going to begin to like it (in a Simba kind of way) and by the time Emma and Co. finally find him, he’ll be a full-on Pan. (Henry Pan? Has a ring to it. Lol)
