Dimitri's expression changed to a more blank one. In general his family almost never cursed, so it was unusual to the son of Poseidon. However, Dimitri had done his share of studying his Greek deities over the past few months. If he had to take a guess as to who her dad was, it was either a mortal who had their priorities all screwed up or it was... "Zeus?" Dimitri asked, though he realized after why making that guess wasn't a great idea. Dimitri wasn't in particular afraid of Zeus because he wasn't very much on the god's radar at all. But, if this girl wasn't a child of Zeus, then he might have picked his words poorly.
"Not that I'm one to judge..." Dimitri tried to make some brightness in his estimate of her father, though at this point, he didn't feel very good about it. "Sorry, that ain't somethin' that usually happens. Just tryin' to make a good guess from what I've learned." The demigod shrugged slightly, deciding to take the honest path, which was something much more his nature. One of Dimitri's greatest strengths and greatest weaknesses was his lack of ability to comprehend social anxiety or awkwardness. Neither situation had ever appeared in from of him, so he had grown up unaware of their existence.
He was still trying to gather how he felt about the first impression with this girl. She wasn't the most fond of him thus far, but Dimitri had considered that that could just be her usual personality. He hadn't ever heard an accent like hers, and he enjoyed accents foreign to his own a good deal. "I guess it ain't my business." Dimitri agreed. He offered his hand to her to shake, something he was taught to do when meeting a new person. "My name is Dimitri Midnight. I've been told to tell people that the surname is real."
