Ok, so Robin Hood stole the wand to heal his pregnant wife. That sounds awful familiar. In the story of "Rapunzel" the father stole the witch's rampion because his wife told him she would die without it. Do you think it's possible that Rumplestiltskin stole the baby for some reason and he takes the place of Mother Gothel? It's just a theory. Although I'm not sure if it would fit in with the timeline. But we don't know how long Belle was living with Rumplestiltskin. It could have been a couple of years. Maybe, possibly, Rapunzel is this new Heidi character, but she will also take the place of Wendy and Peter Pan will rescue her from the tower by flying her out. Again, it's only a theory.
