In my head, if Vali gets the flu, Tia checks in wishes him a speedy recovery and offers to keep him aware of goings on in Court at Charm as she has to tend there anyway. Delanor gushes with Sympathy, then goes out partying. Tiffany informs him in pooka speak that he was BRILLIANT to skip getting a shot this year, she doeesn't like the vet either, and then make him soup, tend to things, and makes sure he eats it and possibly hanging nearby until he's well.
