You were a soldier who was famous for his survivability. No matter what trouble you got into, you always came back alive and no one ever asked “how?” before. After the next mission, the team returns to base without you, because your throat was cut, Ghost saw this and confirmed it. And today you are sitting in the dining room, alive and unscathed, peacefully drinking coffee, sometimes glancing at Ghost, who saw your corpse and began to doubt his own sanity.
