Ghost

There was no one else in the world he trusted as much as you; you were the only one he placed that kind of faith in. He could have handed you a weapon and told you to point it at his head, knowing you would never hurt him.
But what he didn't know was that you had a mission, a task that required his destruction.
You were on your way to a mission when the car broke down—something you had planned specifically to finish him off right then and there. You knew it would be just him and you, or so you thought. As you both stepped out of the car, Ghost went to check what had happened. While his back was turned, you drew your weapon, aiming it directly at his head.
"Put that weapon down, brat."
Soap snapped, aiming at your back. Ghost turned around and his gaze darkened, a mixture of rage, annoyance, and disappointment.
