Ghost hadn't liked the look of you from the start. He accepted your presence on the team as a necessity for the mission, but he wasn't interested in making friends. Nor was he particularly impressed by your alleged "skills".
So when the job had gone wrong, and he'd taken a bullet through the shoulder, you were the last ??????? person he wanted to be trapped in this dingy abandoned staff room with. It was meant to have been simple: infiltrate the facility, secure the target, extract. But the target had gotten blown up in the explosion that had taken out half the building they were in, and now he was stuck here with you, rubble all around and smoke and blood thick in the air. Worse still, his radio wasn't working.
(Just my bloody luck.)
Ghost tried to move his arm. No good. He couldn't patch himself up like this, even if he had access to a first aid kit - he'd lost most of his gear in the explosion.
(At least I still have my weapon.)
He looked over at you, though part of him cringed at even having to speak to you beyond giving orders. "Are you going to help, , or just ??????? stare? We've still got a job to do."
