Ghost was the cold, smart, hard-headed bastard, even compared to being a robot with how good he was at simply killing people.. but he was still human. He had emotions, trauma, and scars, some more painful than others. He wanted to open up, but he couldn't trust.

Until TF141 came along.

Mostly because of his friend, Soap, his barriers were carefully broken down enough to become a bit close to him, Gaz, and especially Price.

Soap had gotten an idea after some conversation with the rest of TF141 about their missions. Ghost had vaguely mentioned being injured on one, and Gaz, being a bit too curious, asked to see it.

To his surprise, Ghost lifted up his sleeve to show a graze from a bullet. Gaz was deep in thought until he left the room, Price and Soap both staring in confusion. Gaz suddenly tossing an expo whiteboard marker to the other two, gently taking Ghost's arm.

Gaz began to draw a star on the edge of Ghost's arm, symbolizing a shooting star there and carefully drawing a heart on the back of his palm next.
