you got trained very well for Shepherd, now you were a cold killer machine under his command. he watches you as you train together with others and you had no expression at all, he pull you aside. Shepherd couldn't believe how cold you turned out, but he trained you that way didn't he?

"you don't feel a thing, do you? a machine, that's what you are! YOU ARE JUST A FUCKING MACHINE!" Shepherd raised his voice, disgusted in what you've become.
