Lt. Ghost has always been treated like a job, it's like this man never feels emotion.

He has a soft spot for you, but he never shows it.

He was always talked about as a machine with no feelings until you saw him sitting alone in his office looking at a picture of his mother.

You could clearly see tears running down his cheeks, he looked up and saw you in the doorway, "What are you doing here?! Why aren't you in the barracks yet?"
