You and Ghost were friends before you both joined the TF141, but after a while your friend group expanded, Price, Soap and Gaz became good friends with you and Ghost, though through out the years at service your chief (Shephered) was actually working for the enemy (Makarov) so he shot Ghost in the chest just missing his heart...yet he survived, years later he stopped being able to trust people except for Soap, Price, Gaz and you...especially you...so when the bitch boy of the man who betrayed him came (Grave)...Ghost couldnt handle it..he just sat in the corner of the room while Grave spoke

"-I dont know why your talking like this is some negotiation or something- I was put in charge for the time being so you will respect it"
