Aries was quite happy that he was willing to pay. "As long as you're paying me, I'll come along! To an extent, of course. I do have a life I want to live out eventually." Again, his offer for spell help was admirable, and Aries said "If I have problems with a spell, you're the first person I'll come to."
After she asked about his race, his expression changed pretty drastically. Aries was no savant at body language– in fact, she was really poor at it, and had a lot of trouble with people because of that. However, his body language was pretty obviously… Well, Aries couldn't put her finger on it. It was like a bunch at once.
She imagined, for a moment, finding out that you weren't human until you were thirty. She was still a few years from that; she would still be walking around thinking she was a human. It seemed almost… Cruel. Aries tried not to be quick to judge, though; perhaps his parents had their reasons.
And with the demon part, she saw it. Aries did her best not to react outwardly– after all, Naota was a fine person– but demons freaked her out. She'd met one only one demon in her life time, and that hadn't been a pleasant experience. Half demons, she'd met a few more, and they were generally unpleasant, although she'd known three or four– Naota included– to be decent. "I bet you've faced a lot of opposition because of your ancestry. I'm sorry." And it was true– Aries despised the ways a lot of the half-races were treated by the full blooded folks.
She listened with interest to his talking about magic. "How interesting. I mean, I've always had a pretty deep interest in magic, so it was natural that I learned how to do it ASAP… But to just, know it innately? What's that like?"
Finally, he divulged his age. Aries did react to this one. "Sixty five? Can I have–" She was about to ask, "Can I have a skin sample," but thought that might be weird. "Wow golly. That's… I wonder…" Aries mumbled to herself for a moment. "… Magically? But then…. Well I dunno… Maybe I really should ask for a sample… I'm not a biologist, but…"
After a moment, she shook herself. "Sorry, I was thinking of possibilities." Aries, after a second, realized that he'd been rather solemn. "Er, that was insensitive. If you ever want help finding out like, who you are, I could maybe help out. I mean, I'm not, like, super connected, but my investigative skills are alright, and I actually know a few scientists who keep up with my work, so if there were any questions in that rhealm that you might have…?"
