[Her injuries are relatively minor, which is good news. Healing is far from his specialty, so he's just got the one spell and he can't do much about serious damage. Her unpredictability is making him nervous on the contact front, but he has to touch her for the spell to work, so he does. He presses his fingertips to her wrist a little warily, holding there for just a few seconds while the spell takes effect, and then—yep okay she's yelling oh my god.]

I'm a sorcerer. It's magic.

[Yeah, so it's definitely not a thing where she's from. Figures. It's rare that he runs into people who are versed in this shit.]

I could teach you sometime if you're interested. The healing's a bit much when you're starting out, but there's easier shit. Like this.

[It's a smooth transition into a thing he wanted to do anyway, especially with the storm threatening to blow away the whole island outside. He steps around her and grabs one of the large shards of glass off of the floor, his eyes moving between it and the hole in the window as he tries to piece the puzzle together.

Once he's found the spot where it belongs, he slots it into place and runs his finger over the crack. As he does, the glass stitches itself back together, and when he pulls away, it's like that piece had never broken off in the first place.]

The tricky part is that you have to figure out which piece goes where before you can fix it.

[And so it's back to the glass pile. This will take a while, but it's something to do. He's been bored all cooped up because of the storm, anyway.]
