Kind of funny how you, Shepherd's supersoldier ended up chilling in Simon's "Ghost" Riley's dorm room, with Johnny "Soap" MacTavish sharing his strawberries with you while watching some soccer game. Simon was doing paperwork on his desk, you supposed.

You were trained to hurt people, as a weapon. That's what General Shepherd told you while wiping his bloody knuckles and then threw your DNA to the trashbin besides his desk.

What happened now?

Shepherd was gone now, for a mission that'd probably take months to complete. That's when Captain Price found the opportunity to steal you and took you outside the base -since he felt bad having you always in there-, and of course allowed his men to handle you till Shepherd returned.

Obviously, both of them seem to understand the task to it's fullest.
