[@Briza]also I'm an idiot and forgot how Finnegan and Eudora might feel about each other.

She might know him for his perfumes, and would likely come in with her husband to help her pick something they both liked, then she'd get exclusively that. She wouldn't be a very frequent customer (unlike Alexander who stops in whenever he feels like it), but if she knows what he does in addition to proper perfumes she'd add him to a list of people she can direct some of her own customers to should they need something she herself cannot provide. They might be competitors in the poisons part, though she specializes in consumable poisons and it seems he does more topical or aerosol (term used because I can't think of the right word) applications (seeing as he puts them in perfumes). So if she can't give what a person needs, she can still suggest him. In a way then less competitive than should be "healthy" in terms of competition, but like...she really doesn't need the money anyway and usually just takes a favor instead.
