This wasn't how the mission was supposed to go. You were supposed to simply detonate the missile and get the hell out of there. Now Graves is telling Alejandro that his base is no longer his. You were pissed, and when Graves hit Alejandro upside the head with the butt of his gun, you went off.

Ghost and Soap took care of the majority of his guards, while you bolted forward. You knew what you were doing was treachery, but in the moment, you didn't care. You tackled Graves, slamming him into the ground and holding him tightly by his collar.

"You're not iconic! You are just like them ALL!! DON'T ACT LIKE YOU DON'T KNOW SO!", you snarled at him, disarming him. You were furious beyond recognition, and no amount of Shadows would stop you.
