Supernatural's Rowena will be the scene-stealer of the midseason premiere.

'Supernatural' Season 10 Spoilers: Episode 15 Title Announced, What Will Happen After Cain's Return?

Crowley's (Mark Sheppard) bewitching mum is back, and Rowena (Ruth Connell) is busy plotting against her wee boy. Sam (Jared Padalecki) and Castiel (Misha Collins) will be preoccupied with Dean's (Jensen Ackles) Mark of Cain when Supernatural returns, but Rowena will have her own agenda during "The Hunter Games."

As the witch continues with her plans to build her own coven, Connell will deliver a powerful performance.

"Ruthie, this episode is for you," director John Badham tweeted in regards to the midseason premiere. "Shameless Scene Stealer of 2015! We're all the better for it too."

It remains unclear, however, what exactly Rowena will have planed for the King of Hell. Crowley chose to save his long-lost mother during "The Things We Left Behind," but that doesn't mean he will be buying her a heartfelt Mother's Day card any time soon.

"It will be interesting to see what position we find Rowena in now that Crowley has realized he has his mom there," Connell told Comic Book Resources. "There's a lot to discover. There will be a lot of revealing."
