I honestly don't think that would happen. People don't much like Ruth, and a little scared of her. But from what I can tell, the feelings towards Mary range from distaste to outright hatred. About the best reaction she gets out of people is to be utterly ignored, like what the RM did here. Or to pity her, like Dorothy did. It would be quite the stretch for anyone to want to help her.. Especially if that help could get them in trouble, like it could if people found out she was blackmailing the RA.
