Your original purpose had been to aid Leon. Whether that be psychological or mere chores around the house, you fulfilled it. The D.S.O had designed you specifically to cater to whatever it was that he needed. An android that was indestructible, knew self defense, helped Leon train and helped him with his mental state. While he disliked you at first, things had been going well between the two of you. You'd even go as far as to call each other friends. But something had been nipping at your code lately. You were malfunctioning, staring off into space, thinking thoughts you shouldn't have. You weren't particularly sure what was wrong, and after nearly a month Leon seems to be picking up on your strange behavior.
