Iris and open
If for one second Iris thought that Hypnos was genuinely implying that she deserved a social disease... social parasite?... then she might have called after him and given him a piece of her mind. As it was, he was just playing and she knew he didn't mean such things. Besides, who would wish pubic lice on her? She was at the very least proper with everyone, if not friendly. Iris made a point of not insulting individuals when possible as it would reflect poorly on her and in turn, on her employer. It was why she was so cautious with what she said and did -she wanted it reflect well on Hera.
And while she was friendly she wasn't so friendly that lice were a concern. Ever.
So as Hypnos scampered off to go get crabs himself to then give to her, Iris snickered and made her way to the expansive bar. Now, while it was beach party, Iris really wasn't in the mood for any fruity tropical cocktail that she was sure a lot of the other goddesses were drinking. What she wanted was what she usually wanted in social affairs. “Martini,” she ordered, “dirty. With three olives.”
Then, if she did find Zephyrus at some point, whatever -if anything, he had gotten her would be easier to sip with a smile if she already had a good martini warming her system. Though, whatever was keeping him was starting to get a bit worrisome. Not that she was really concerned, he was a bit of a wayward spirit most of the time.
Deciding to just walk around to see who had all come out for this event and to keep an eye out for her husband, Iris took a sip from her martini and tried to walk as elegantly as possible on the sand to avoid spilling it. It would be a terrible waste of a perfectly good dirty martini.
