This is Sam’s decision and for once in his life, he’s going to make the right one. Because this isn’t about him. This isn’t even about the end of the world. It’s certainly not about Michael and Lucifer.

This is about Dean.

Sam believes in Dean.

In the end, that meant everything. Because it took that for Dean to find the faith to believe in Sam. And it took that to save the world.

Darn you for making me all wibbly again!
