Remus / Sirius
It wasn't like Sirius wasn't clever -- but Remus always had been better at puzzles, all while Sirius usually stood around and complained about the design of them before he bothered attempting to figure them out at all. In this instance, it was because he was rather surprised by the sheer amount of blood it might take to write something like that on a wall so largely.
He glanced over at Remus, grey eyes gone solemn, without humor. This hotel was not for them, but it was certainly possible the note was. MURDER. No. He'd been avoiding that, and intended to keep his streak up. "The door?" He asked, quiet. "Yes." He hadn't stepped in. He didn't want to either. But there was also something -- something in him that sort of felt like he ought to, just the same.
