They put their hand over their heart, and sweep that hand out toward Harley, a silent thank you for her praise.

There's not much to clean up, but they do their best to help put things back in order, the silks waiting for their next dancer to come along. Probably Harley, since they are hers, after all. But it's a show of respect for her, as well as a thanks for letting them give it a try.

I know I've lost people too. I don't remember them very well.
