Rin would find Yukio in one of the back rooms, absorbed in taking inventory of the clinic's depressingly small store of supplies. Not quite so small as it had been the day before thanks to an early morning scavenging of the hospital, but still far smaller than Yukio would have preferred. Heaven forbid more than two or three serious injuries every come in at once. He'd end up sewing wounds shut with dental floss.

Caught deep in thought and just a little bit of his ever-present worry, he didn't realize he wasn't alone in the clinic until Rin actually stepped through the door of the back room.

"Niisan? Is something wrong?"

Because why else would Rin be at the clinic in the middle of the day?
