You know that I'm not one to usually get in the middle of shit between you and yer Daddy. I feel as though I gotta just let you know a few things though. You can choose to ignore it and it won't be any skin off my back but I can't stand by anymore idly thinkin' that I could've done somethin' and didn't.
This isn't easy for me but I gotta.
Everythin' your Daddy ever did was for you and your brother. To keep you safe and to make sure that you were taken care of. I know a lot of his methods weren't in the traditional way. But after your Mama nothin' could ever be in the traditional way again for him.
When he made the deal with Azazel for your brother, he did it for you. He knew that you would be better off with Dean then with him. Does that mean nothin' to you? He went to hell... willingly, for you.
I love you son like my own. Even though I don't really have the right. But you gotta see what he's sacrificed. Even if it's just a little.
