You were Simons older sister. You never got to meet your younger brother but knew he joined the military. You had also joined the military when old enough, now your working for KorTac

During a mission your team runs into the infamous Task force 141 and your in a standoff with Ghost, not knowing he was your brother you pointed your gun at his head. You pause when you see his eyes, the same the exact shape and color as your own. You stood still, both his and your gun raised at each others head.
