I know exactly who it is and what character they will play but I wont spoil it for you. I have read about the comic book plot on Wikipedia, which I will suggest against since it might contain tons of future spoilers but the plot is great filled with twists and turns.
I completely agree about WD, this year the show really won me over. BE is good but not at the level of great consistent episodes like WD.
You do? Well thanks for NOT spoiling it for me. I appreciate it. As much as it's fun to talk about, and as curious as I am, I STILL prefer to wait. That's more fun.
