It's not very often that Dean yells at him. Yells around him, yells in him, yells in the woods near him, but actually yelling at him is rare enough that it startles Baby into shocked silence.

He stares at Dean with wide eyes and then he stares down at his hands, fiddling with them while he gets scolded. He didn't mean to make Dean angry and now he's sad. Baby is a sad Impala.

He'll just be quiet for now until he figures out more of what he's allowed to say and what he's not allowed to say because apparently, everything he's said in the past five minutes is all firmly on the Not Allowed list.
