I haven’t seen this theory anywhere else… I recall Adam and Edward indicating we would see Tinkerbell in Season 3, and she might have her own background story or arc. What if Henry’s heart is needed to save Tinkerbell’s life? In the Disney version, kids needed to clap or say “I believe in fairies” or something like that to save Tinkerbell after she drank poison. What if she needs the heart of the truest believer to be saved? A long time ago, PP may have obtained an image of Henry from Rumple, who is able to see into the future. If PP is able to “fly” into our world without the need of a bean, it makes sense why Rumple would want to negotiate with PP. That also plays into why PP is “complicated” and not just flat-out evil. He is trying to save his friend.
That’s interesting. But then why does he need all the other boys? He won’t let them go home and I think this means that while Henry is the ultimate need for PP, he still needs other boys for something.
