"He was a lot of things to me" "The only conclusion was love"
Remember the BF had to have dust for her wand she had no power and Blue is suppose to be more powerful then Tink. Remember didn’t Regina ask Blue to take her back and give her wand back?
And then remember that Gold and Regina used all the diamonds in the mine to block the well, but then 5 episodes later the BF had her wand and was using it (poorly) to try and get past the spell around Gold’s shop.
Regina never gave anyone’s wand back. We don’t know how Blue got her wand.
