It wasn't exactly trying to be hidden, it WAS trying to lead the drones out of the area where Draiss was. However, it was also trying to get data, and the organics AIs refusing to be reasonable was starting to seriously annoy Reaper. The fact it wasn't able to shake the drones after it started trying to was just another annoyance. It wasn't terribly concerned about not spotting a drone, Reaper had the most sensitive and varied sensor packages among the constructs, so it was fairly certain it was spotting them all. It was also fairly certain it had been spotted by one of the quality drones, especially after it hacked one, and brought the drone close enough to allow it to examine it.<br/><br/>Still, after destroying the drone and continuing onward, it made a point of at least going through the motions of being stealthy, getting more and more map data, including from local organics. It was trying to find a spot it recognized, so it could start making its way toward the area that Jashah and her people stayed. They needed her help in fixing the Creator, as Draiss' beyonder was also hurting, and was the reason he wasn't healing himself.
