You both had become friends. You thought he was one of you. You believed him, God, you fell for him.

You discovered too late. Only when Task Force 141 appeared and started to kill your friends, because of the intel you gave Ghost. Because you told him where you and your team would be.

The tears invade your eyes. You find him in the middle of the mess. He doesn't even look at you, focused in shooting his enemies, your people. When his eyes finally meet yours you know he's about to kill you.
