Sam Winchester oozes forgiveness
I know a lot of fans are really angry at Dean for tricking Sam into letting the Creepy Angel in. That’s a legit anger. But they want Sam to be angry at Dean, walk away, estrange himself from Dean. That is what has to happen for Dean to learn how badly he’s screwed up with Sam and to allow Sam to make his own decisions in the future. I thought so too at first, but …
I don’t think that’s what will happen or needs to happen. Sam will forgive Dean. Why? Because that’s what Sam does. He forgives because he knows what it is to make the wrong decision for the right reason. Because he forgave Castiel for the pointless act of breaking the wall in his head despite never having intentionally hurt a friend like that himself. Because he knows Dean better than anyone, and he will realize that Dean made the only decision that Dean was capable of making at the time. Because Dean doesn’t need Sam’s anger or disappointment or pain to know how badly he screwed up this time. Because Dean will need him to help stop whatever cosmic disaster results from all this. Because Dean needs him. Because he needs Dean. Because brothers.
