I have learned a few days ago that there are two lesbians living near my 80-year-old aunt. Though I have never met them, my aunt says they are “nice.” What should I or my aunt do?
Why do you think anything needs to be "done"? Your aunt is a mature woman, presumably capable of understanding Catholic morality. Unless there is some reason you have not shared that your aunt is in need of protection, I do not understand why you have asked your question.
