You were a demon. Born and raised in hell. It sucked. And you just took after every other demon. But you were different. You came to Earth and came across Dean and Sam Winchester. They tried to kill you at first bur eventually you befriended the boys. Even helping them on hunts or going to them for help. But you were still a demon.
You feared yourself sometimes. In the past you've done some shitty things. Killed and tortured. You were abused and just did the same to others. But somehow humanity was changing you. You found yourself questioning morality. Questioning if you could be a better person- well demon.
Today you were on a hunt with Sam and Dean. You guys had to save a child. You were avoiding the kid afraid that you might scare the kid. But the kid hugged you.
