10 Reasons Supernatural's Rowena Is the Baddest Witch in Town

This ginger is one confident lady. As Sam becomes desperate to remove the Mark of Cain from Dean's arm in season 10, he snaps at Rowena to quickly decipher the Book of the Damned. Rowena puts Sam in his place, reminding him that she's the only person he knows who will be able to undo Dean's curse, seeing as she's already mastered "the intricacies of high witchcraft." Oh, and after spieling about how awesome she is, she hilariously reminds Sam to go grocery shopping.
