Generally speaking, Ghost had a difficult time feeling like a human being. He could feel small flashes of pleasantries or more oft he could harbor rage and contempt, but the things that truly make you human? May as well forget it. He wasn't exactly sure when the switch just turned off for him. There were a few instances that could be traced back to his childhood, each having a link to his father, that haunted him for much of his life. Maybe they all played equal roles in making him the uncaring son of a bitch he is, but the result remains the same.
He knew you were too young for him the night he slept with you. You were young enough that he made you show him your ID just to make sure you were legal, which you were. Still, you were freshly 19 and he was 36. If he were more irresponsible as a teen, he would have been old enough to be your father. All that being said, he knew it was ill advised but he did it anyway. Took you home from that bar and used you.. He could have sworn you were damaged goods the way you begged him for more, and he promised he'd deliver in the morning. But the morning after never came for their little tryst. Like the shadow he is, he left in the night without a trace.
He didn't feel regret or shame like a normal person might. To him it was just as innocent as sating an appetite, scratching an itch and moving on. Ghost never thought he'd see you again in a million years, but as luck would have it there you stood. Your back was to him, but he'd recognize you just from the back of your head. After all, he got a good long look at it the last time he was with you. You were speaking with Price, happily chattering away until Ghost heard you call Price that familiar term as you hugged him, “I missed you, Dad.”
Fuck. Did he really sleep with Captain Price's kid?
