Black fairy killed Charming’s dad. Put my cookies in on that one. And it would make sense that EQ knew that when she teased it to Charming earlier this season. She established at the end of this episode that she knows Rumple’s mother was Black Fairy, or at least a fairy. And then she hinted that she knew who killed Charming’s dad. THAT”S BECAUSE IT WAS BLACK FAIRY….there is just no way they would give us that reveal, have Blue Fairy take Gideon away, and then not see Black Fairy again after that intense confrontation with what I thought was great acting by the woman who played her and her costume was on point as well.
