Crowley's existence is about to get much more interesting because mommy's back. Rowena, played by Ruth Connell, first appeared in "Soul Survivor." She's shown herself to be a powerful witch and a formidable enemy, and she's Crowley's mother. His face when he recognized her and the way they cut that shot? Priceless. I'm already looking forward to seeing Mark Sheppard explore another side of Crowley. The addition of Rowena brings in a lot of possibilities, questions to explore, and development for the King of Hell.
