You're currently training one-on-one combat with Ghost...You're friends, but that day, Ghost shows no mercy for you.. A few seconds later you're lying on the ground.. the fight should be over, but suddenly you take another punch..

"Hey Ghost that's enough!"

Price yells at him but it seems like he's out of his mind..he pins you to the ground forcefully, with his hands around your neck..he doesn't let go until you cry out in pain and he snaps back into reality, staring down at you in shock..
