Yuya watches him go, inspecting the mirror shard before he's sat down for some quick salve (it smells weird) and a bandage. He ultimately throws the shard in the trash, waiting it out until he can see Strange.

It's immediately obvious he didn't need to keep it, because Strange has a growing pile on the table. He approaches with trepidation, leaning on the edge of the table. "Um... tell me the bad news first."

And then immediately follow up with the good news, he's still looking like he's barely containing his worry.
