Dean's boyish features fall at the idea that she's eating people. Why was everything so gray here. He's used to black and white and he's suddenly not sure he should even be here. Not when he could be on the menu.

"Uh, well I guess eating in self defense isn't as bad as makin' a meal outta people just 'cause you can," it sounds weird even to him so he just swallows and moves on.

As long as you don't try anything fishy with me and my family or anyone else and keep bein' neutral we won't have an issue."
