This is a website screenshot and notes on a woman that Aaron has been stalking. She does not quite fit his idea of corporate world and a person that is a slave to their own vanity since she shops for junk. Looking at the street view of 16th Street we find that it is mostly a housing area, so this would mean that she was a garage sale picker. Not at all befitting of his idea of corporate world even though she does work at a law office. So this points back to John Blaine.
