Kitty
The receptionist is more than distracted by his own call, ringer or no, and Kitty easily moves past his desk to the fire stairs up to the fourth floor. While most of the professors have their office doors decorated with newspaper clippings, little cartoons, or cheesy linguistics jokes that don't quite make sense to her, Brunner's door is entirely devoid of ornament except for the room number and a placard reading "Dr. Tobias Brunner." Unsurprisingly, the door is locked.
Leo
The back room is even smokier and stiflingly hot than the rest of the cafe, somehow. Another large fire burns brightly in the grate as a small knot of people, seated on squat barrels instead of seats, argue good-naturedly over a mess of cards and beer glasses. Whatever game they're playing is completely unfamiliar. Leo recognizes them as Ziggy's close friends, all of them supernaturally clued and some of them with formal magical training. The only real wizard among them, however, is the one emerging from a corner of the room and trying to hold five fresh glasses of beer in two hands. "Now then, now then, I'm certain it's not your deal--Leo, my boy! Good to see you again! Have a seat and drink up, you look dead on your feet." One of the glasses is thrust toward Leo while one of the card players drags over another barrel. "I assume you're not just here for some company? If you want in on the game, though, Lennert here is staggering home in a few minutes, and we could use a fourth who's not too blind to see the cards."
