Hmm well we never really got closure on why Cinderella’s fairy godmother “won’t be missed” or whatever it was that Rumple said about her after he took her wand from her. Maybe she and this Black Fairy are somehow connected. It’s a different wand, but maybe there’s a league of not-so-nice fairies wandering around making trouble for everyone.
…..Assuming you aren’t saying that due to the term “Black” Fairy and the godmothers race, I think that while ita possible, its unlikely. That fairy was working for king Georges family for awhile according to Rumpel. I think if she knew anything Blue would have gotten rid of her. Or rump would have interrogated her, not kill her on the spot. I think rump just wanted her wand for the Cinderella deal.
