CKR guests in the second episode of Supernatural and AA is in the third. My Canadian and American sci-fi television worlds have collided (Where is Supernatural filmed?). Also, that is wonderfully good taste in guest stars.
I'm going to go watch the fourth episode now. I have high hopes that Dean will continue to be the softest-hearted demon hunter in existence (seriously, how does the man survive? He's totally Angel: the Woobie Years, saving puppies from speeding cars) and that Sam will be way hotter than he was a few years ago (I can't get over how cute I think he is now -- I scoffed when people called Jared's character on Gilmore Girls CuteDean, but I think that Sam is just adorable and broody. I guess personality really does have a lot to do with what I find attractive.).
