But (Spoiler) he still lives. But in all seriousness I really did like this episode.
But on another note, I really need to hand it to Jared Padalecki. First he had to handle being normal Sam, then 'Lucifer-possessed' Sam, then soulless Sam, then having-a-mental-breakdown Sam and now he is being both Sam and Ezekiel. And I think he is a brilliant actor for being able to pull of so many faces for one character.
