i think shes just meant to be an embodiment of the unseen damage that walt caused by killing gus. here we have this chick who we dont really know anything about other than shes some minor player in gus's empire, and works for madrigal electromotive and obviously makes some huge bucks, looking at her house. and shes panicked and her perfect little world shes built through most likely illegal means is being threatened by gus's death, so much so she freaks out and tries to have 11 people wiped out to protect it. shes like the embodiment of the unseen chaos that the arrogant walt has caused by killing gus
all in all i think shes just part of madrigal electromotive, makes good money but wanted even more, to provide a luxurious life for her daughter. she 'broke bad' in her own way by doing whatever she did to get connected in with gus, cooked his books or supplied chemicals or whatever she did. and shes breaking even more bad by trying to kill everyone who could connect it back to her, and now shes in deep way over her head.
walt thinks hes some kind of genius but he sent out shockwaves throughout the world that he cant even see yet, and i hope it destroys him. you got all these people losing their money, getting talked to by the DEA, all this shit walt doesnt even know about. lol meanwhile hes trying to live in some kind of sick and twisted idea of a family with a wife hes holding hostage. and hes maintaining all of these hollow disgusting friendships with people and family that hes screwed over in ways that should be punished with death. what a sick fuck
