What if the Blue Fairy was a love-interest for Zoso before he became the DO and then BF is secretly bitter at Rumple for killing Zoso; even though the BF knows she can't be with Zoso because he's the DO (forbidden love). So she gives Bae the magic bean so the DO will go to Earth and the presence of her forever lost true love (Zoso) is gone.
