I really liked this episode.Sam is becoming stronger and stronger and blood is being provided to him by Lilith. Sam and Dean fought each other and boy it turned out good.Every episode of supernatural has been good so far. Now Sam is making his way to the hospital to fight. Will dean be able to stop the hell from being released on earth? Supernatural is getting to be more and more interesting as the show unfolds the plots. Every plot in the show has been a fantastic ride. Sams strength has increased dramatically. I can hardly wait to see next weeks episode. What will happen next. I want there to be a season six. Don't let the show end after season five please. Eric Kripkie is gifted with great intelligence. Supernatural is a dream ride. Rock on Kripkie.
