Hmm, what sort of mistake? What friend? The list of people that Melpomene knew Marcie was acquainted with was very short, after all, but Melpomene didn't claim to know everything (yet). Still, it was likely someone here. She'd have to keep a sharper eye out, when she stepped back inside; she'd only seen Marcie with Ares and Aphrodite. Surely not one of them nymphs. "I'm sorry," she told Marcie, passing over the cup. "If you get too bored waiting in the car, you can come inside and find me. Otherwise, let's meet up soon?"
