Ruth Connell will reprise her role as Rowena on Thursday's episode of Supernatural titled "Regarding Dean."
The episode will find Sam enlisting Rowena’s help to track down an old world, powerful family of witches after Dean gets hit by a spell that is rapidly erasing his memory.
Here's a preview on what to expect, per Connell:
It’s interesting where this episode picks up. The first scene, I’m in a gambling den. [Laughs] Her romance didn’t work out… so she’s been entertaining herself. Then the Winchesters need her help. She’s drafted back into action. There’s something in it for her, as well. The episode revolves around this witch family and a book they have, which is called the Black Grimoire. I’m very excited for Rowena to know about this book and get her scrubby paws on it.
