She was simply fantastic in Dexter.

Season 2 is my favorite season of the entire Dexter franchise, mainly because of her performance. She is by far the best antagonist of the show, in my opinion. Her manipulative, sly, and apathetic nature gave me the chills, along with her vampire-like porcelain skin. I've never seen a female able to be so disgusting and yet so attractive at the same time. Remarkable.
