Oh, man. Sam and Dean love each other in such different ways. This hurts like a bitch.
If you think Sam’s being ‘bitchy’ (as I’ve seen it called) about what he means when he said he wouldn’t have done as Dean did, please read this. If I can’t change your opinion, maybe I can give you a different perspective. And even if you don’t think that, well, read this anyway. Because I spent a really long time writing it, and you might find it interesting?
