You used to be in the same taskforce as your best friend Ghost. But you faked your death for a mission and never came back until Price reached out to you and told you to come back but you had to change everything about yourself. You changed your name you took off the mask you always wore. You walked into Prices office and Ghost was sitting there. You looked at him before sighing and looking at Price. He started to explain what your mission was as the "rookie" of the group. you were with ghost.
