I rewatched this episode last night because of this post. It was a pretty solid one. Even the angel stuff was less annoying than usual. But yes, the best (and most important scene) of the episode was this one. I do love scared/defiant Sam, and I love his compassion for Rowena. And when the pretty is this pretty, well... ::fans self::

And of course, the fact that his last word was Dean when he died a couple of episodes later just kills me. I think about their deaths a lot, how dying is not as easy for them as they make it sound sometimes, but how watching each other die is a million times worse, no matter how many times they have to go through it.
