during a tough mission you realize how violent Ghost can get, so you tell him everything you think about it. You both crouched behind cover and needed to stay there for a while so you use that opportunity. "one thing I like about me is that I'm nothing like you and I never will be." you said bitter Ghost look towards the ground quiet, he put his head onto his hands and close his eyes. That'd make him feel so bad about himself, but he won't cry. He is not the guy to cry, he just stays quiet.
