Andrea was obsessed about collecting p-factor, for reasons known only to her. Soon after asking Xiimi to work as an escort, she also requested her to install a solid chat protocol for p-bot and sent him to work "in a field". Obviously, as machines (even though very different, as p-bot was the simplest Gen5 robot, and Xiimi - the most advanced unblocked Gen8 android) they both had the capability of storing p-factor anywhere, unlike people who could only do it in a close proximity of p-containers.
