I'm telling you... these things are freakin writing themselves this year!
All he ever wanted was his brother. That want had turned him into a hypocrite.

When you love somebody, you're supposed to let them go. Dean had decided back in South Dakota that that particular notion could go screw itself. He had to save Sam. What the hell else was family for?

Hell. He was going to Hell at the end of the year, and Sam knew it. But Sam just couldn't let him go, couldn't let him rest, couldn't let him suffer alone. And deep down, deeper than he ever liked to go, he was glad. After all, what else was family- real family, family that cared and put Dean first for once in his life- for? It was because of this that he knew he was selfish.
