"Assbutt," Baby murmurs petulantly, pout firmly in place as he slowly picks himself off the sidewalk. His mood changes from petulant to ashamed when he sees Dean.

Dean is angry. Baby has been a bad car. Baby is sorry. He doesn't want Dean to be angry with him. Dean's always been angry at everybody else, but very rarely at him.

He doesn't want to be left alone under a tarp forever! He wants to tell Dean that he's sorry, but what actually comes out of his mouth is: "Assbutt started it."
