"Oh, oh, oh dear... Oh dear, dear, dear..." Shaking his head, the Professor dropped his bag and dug through it, producing various vials, jars, and smaller bags. Opening one of the jars, he scooped out a blob of some thick resin and used it to pack the wound. "This, this m-may sting... but, but, but it will seal it..."
Smearing more of the resin on top of the stopped wound, he applied a poultice and covered it with a bandage.
Cleaning his hands, he assessed the broken arm. "I, I, I will need to set that, and, and I can assure you that it will hurt."
He rolled up a blob of resin and handed it to Aya to bite down. Carefully, he placed both hands solidly on Aya's arm, both above and below the break. "I will c-count to three. On three, I'll, I'll, I'll set it. I do advise you b-bite down on that. Ready? One... two... THREE!"
