OMG! Amazing episode.
And
Kripke darn! Why do you have to be soooooooo cruel. Just give us the darn answer.
I cannot wait for the new episode.
I love the brotherly scenes especially Dean's
"You'll be dead before you hit the ground" 
And he's giving the Impala away.
That sure said A LOT about his love for Sam.
I was thinking that Dean kept on killing these people that supposedly had the virus because he's protecting Sammy. Somehow, he had an idea what the demon is trying to do. And he couldn't answer Sammy why he kept on killing people without any sign of hesitation. The answer is - it's all about Sam.
I love these two.
