I don’t think the writers are trying to turn Belle into Snow. I think they’re trying to give Belle her ultimate dream before she gets captured by Regina. Belle always desired fun and adventure, and the girl had more bravery than she knew what to do with, but she had no place to channel all that positive energy. Her father groomed her from bith to be a perfect little duchess, then she gave herself up to Rumpel and became his servent in order to save her village. And even though they eventually fell in love, the fact remained that she was still a caged woman. So, I’m glad Belle got the chance to spread her wings and go out on her own. 🙂
