What is he going to do about it. Now there's a question. Because again, he doesn't want to test the limits of this place. But wow is Sherlock so many different kinds of annoying.

So what he's going to do about it is apparently be equally petty. He has the incantation at the ready, after all. With a gesture of his hand, Strange called forth a small gust of wind directed at Sherlock...or more specifically, that ball he's tossing up and down, intent on magically knocking it out of his hand.
