Technically, Elvyran wasn't in school, but he was still studying. He could use his powers, sure, but he still needed to learn so much more than how to stick his hands in something and fix it. He needed diseases and afflictions, side effects, perscriptions -- all the things that didn't necessarily actually have to do with surgery. So he brought his books with him, figuring he could do some of his own studying when (and if) Sarena got the hang of what she was doing and went off on her own.
Elvyran took a seat -- not next to her, but near her, setting down his bag. "So. Where do we start?"
