Sit down.

[Lev instructs without even a waver in his voice. He's used to this. He patches Abby up all the time. Then once Nico is settled, he rummages into through his quiver and pulls out a small package of alcohol, rags, gauze, and a needle and thread.

Setting that near his feet, he gently raises the bloodied sleeve to inspect the wound, wiping away some of the blood with the rag. It seems to have come from the strange place they were in, like his skin just split open, rather than something cut him.]

I don't think you'll need stitches. And it's a clean cut so it should heal well.

[He pours some alcohol on the rag and pushes it against the wound. It probably hurts so if Nico squirms, Lev doesn't react. In fact, he seems pretty unperturbed by the blood.

Then with gentle fingers, he uses the a clean rag and some gauze to dress the wound.]

There. Just don't overuse that arm in the next few days.

[His own shirt has blood on it now and there's a smear where he rubbed at his face without thinking about his blooded hands.]
