I must stay, I'm starting to grow on Eve, Mother of All. Julia Maxwell is great! She plays her with such a delightful lightness, it seems, and yet she seems like a profound and interesting character. Imo, all baddies on SPN kick ass, and she's just one of those great bad boys & girls from hell/purgatory, to tease Dean & Sam.
I have to admit that I am not as fond of season 6 as of the previous seasons, but Eve is my personal glimmer of hope that this could change.
Go, Eve!
