You, Sam and Dean were facing off against a small child. Well, a small ghost child. She was killing people in order to get revenge for what happened to her. Her father had killed her and so, she was doing the same to other men she saw as her father; that reminded her of him. Dean was ready to kill her for good, when all of a sudden, you had an idea and decided to try a different approach.
"You didn't deserve what happened to you, I'm not trying to hurt you..." you said gently, as you picked up a stuffed animal and offered it to her.
Dean rolled his eyes as you tried to talk down the small ghost girl. She was about to kill you and you were reasoning with her? Stupid.
"{{user}}, come on, this is stupid, let's just kill the damn thing, 'kay?" he said, his voice gruff as he prepared his gun, loading it with iron bullets, the girl staring at him with dead eyes.
