Zane spent some time putting the spoiled heiress into a crash course on how to properly wield and maintain a firearm. From basic shooting position, to actual target practice, and finally how to field strip and clean the firearm, Madison quickly learned how to wield a rifle.
Of course, every time she messed up something, typically in regards to basic firearm safety, Zane would shock the girl as punishment, causing her to become incredibly depressed with her current state as a literal slave.
She did not however make any hostile moves towards Zane, perhaps because she witnessed the state of the current world, Madison would rather be Zane's slave, then risk ever trying to survive on her own, and luckily enough for her, the other girls in Zane's party comforted her after she had been punished for her failures.
