Dean, the Righteous Man
Dean Winchester doesn't think he's righteous. He doesn't think he deserved to be saved. He just wants it to be simple again. Dean wants his baby brother with him on the road, fighting monsters. He wants them to be as close as they once were. He wants to be Sam Winchester's big brother, the man he could always go to no matter what. He wants to be that asshole who loves 'em and leave 'em. He wants to be that smart ass who doesn't care about anything but his family.
He doesn't want his mask being constantly ripped off. He doesn't want the pressure of saving the world.
He just doesn't want to be the righteous man.
Castiel, the Angel of Thursday
Castiel likes his vessel Jimmy. He likes how devoted he is, to god and his family. He especially likes his eyes. He has vibrant blue eyes that shock him to the core. They are like the stormy sea his Father walked upon.
Castiel sees himself in those eyes.
They are like the tears of sadness he has always felt throughout his entire existence, for feeling every mortal's grief is apart of him. It is who he is. It is who his Father made him. It's why he wants to save the human race so much.
Cas knows their pain; he doesn't want to inflict anymore on them.
Sam, the Boy with Demon Blood
He was a freak. No, screw the was. He is a freak, and it would seem it was destined to be like this. Damn God and his damn angels. He's always so angry. He's angry at his dad for raising him and Dean as warriors. He's angry at Yellow Eyes for making him a freak in the first place. He's angry at Lillith for killing his brother. He's angry at Ruby for tricking him. He's angry at Lucifer for revealing the truth to him. The truth that he was his true vessel. That they were so much alike.
And Sam's angry that he'll always be known as the boy with demon blood to everyone who seems to be important.
