When Barnaby heard a knock, he didn't waste any time in striding over to the door and opening it. He was greeted by Kotetsu's masked face and out-of-place smile -- and an unfamiliar man standing at his side. Muted surprise crossed his features, but he promptly schooled his expression into one of neutral indifference.

"A friend of yours?" he asked, his tone distant and polite. Although Barnaby's cool gaze settled onto the stranger, the question was obviously directed toward Kotetsu. "I didn't realize you'd need help finding my room."

Or maybe he'd just collected a stray on the way over here. With how unwell some of the patients here sounded, and Kotetsu's constant need to butt into other people's personal problems, Barnaby supposed that wouldn't have surprised him, either.
