Why didn’t the Blue Fairy go with Baelfire after their little chat and explain to Rumpel the solution she offered Baelfire and then leave them to dicuss it. Instead she went behind Rumpel’s back and gave his child an extreme choice. Baelfire was desperate and the Blue Fairy kind of took advantage of that because getting rid of the dark one would be beneficial to her. She likes to make out she’s all goodness and light but I don’t think she is.
