This is what the Blue Fairy said about magic beans in the episode The Return (1×19)
Blue Fairy to Baelfire:
A magic bean. The very last one that is known to our kind. The others got away from us. You just use it wisely, and follow wherever it leads you. It will save you both.Blue Fairy to Rumple:
You had the way, you didn’t take it. And there are no more magic beans.
Guess most of us remember better what she told Rumple, but she said something slightly different to Bae: it was the last bean the fairies knew of.
More fuel though as well for the theory that the Blue Fairy has her own grand scheme running and manipulated Rumple in this moment. I read it differently, but can see that one can read it as the Blue Fairy telling Rumple not the whole story.
