This is what I found suspicious: when Blue and the Charmings were trying to get into Gold’s shop, Blue and her wand were totally ineffective. Shouldn’t the greatest good in the land be able to get past the dark magic of Rumple because the moral of this show is “good always wins.” For a Fairy who is supposed to be so powerful, she’s not exactly good at her job. She basically TOLD Rumple about the curse, then sat back and let it happen. All this leads me to Sneaky Fairy is Sneaky.
I agree with the above and add why could Cora protect part of the land and the Blue Fairy couldn’t do anything to save anyone or even part of the kingdom. I thought the Blue Fairy had more power then Cora and Rumble. ❓
