"I guess it would be what you'd call herbal medicine." He didn't immediately elaborate. Instead, he waited until he felt the healing was done, turning Walter's arm a little to make sure there wasn't anything left. The shirt would have to be mended.

"That time when I ran out in a storm when I was a child," He'd mentioned that in passing before. He speaks now as if he expects that Walter still remembers, "I'd been carried back to town and the person who held me had smelled of medicine like this."

Because there's no way to describe what sort of medicine he smelled. He doesn't say who his saviour had been, but there's warmth in his voice that may be familiar from when they last spoke about Gu Yun.
