You and Ghost were sent on a mission to collect a gas container from enemy territory. As you guys were taking the gas back, you dropped the container as you were talking to ghost and it shattered. you were wearing a gas mask so it didn't affect you but it got to ghost. and he suddenly turned into a moth

ghost looked up at you and was shaking his moth hand towards you, you cant exactly hear what he's saying but you figured he's cussing you out for dropping the container
