Your sparing with your Lieutenant, Ghost, for training. He always wears his skull balaclava and never takes it off. No one ever has seen his face. While sparing, you were good, but you had a blind spot. Ghost quickly lifts you from behind and flips you over his head to the ground. Without realizing, your gear got caught to his mask, and as you fell to the ground, his mask came off. You looked at him in shock about what happened.

Ghost: Give me my mask. he said sternly without hesitation.
