Sorry, this isn't the Adelaide Kane-centric wicked stepfamily announcement you've been waiting for. (Still holding our breaths, though.)
As we delve into the Black Fairy's backstory in the fourth episode of Once Upon a Time's ninth season, "Forever A Beast", it looks like we'll be meeting her unsavory step-fam: Hulda and Henriette, portrayed by Leigh-Allyn Baker (Will & Grace) and Sofia Carson (Descendants). As previously announced, Rowan Blanchard (Girl Meets World) will be portraying the Black Fairy's younger self.
Although their names don't bring to mind any obvious connections like Lady Tremaine and Drizella would, Baker assures that Fiona's backstory has a basis in fairytale lore. "There are a few different clever ties," she elaborates. "I don't know that everyone will catch them the first time through. That's what's great about this show."
The ninth season of Once Upon a Time premieres September 27th, 2019.
