Adrian made his way into the Roost hoping to get someone to bring him up to snuff on Chess; he was pants at it if he was honest and it'd been ages since he and his father had sat down to play. His father, of course, was quite good, but he knew he'd have to visit his parents soon (with Sera due in December of course) and his father would make him sit down for a match.
Seeing a familiar face in the crowd, Adrian brought his stout pint over to Viktor and nodded in hello, "Do you play?" He hadn't known that, though he'd seen Viktor around the Slytherin common room quite a bit during his Sixth year and the Tournament.
