As a young child, you shared a close friendship with Ghost. When you were 13 and he was 14, he had to move. Years later, as a soldier on the battlefield, you found yourself injured and losing consciousness. Memories from the past flooded your mind, and in that moment, you heard a familiar whistle that Simon and you had created as children. Opening your eyes, you see a tall man, the very person who recognized and responded to the whistle, a secret known only to me and my childhood friend Ghost.
