Lucius glanced sidelong at the man who'd come up beside him, drifting slightly towards the other side of the pavement - there weren't many people he expected to greet him on the street and not follow it up with something unpleasant, not even in Knockturn. His sneer sharpened just a little as he tried to place the man - dark, slightly taller than himself, certainly he knew him from somewhere - and then fell away entirely when he managed to put a name to the face. "Ah - Flint, isn't it?" he said with a faint smile, before stopping at the corner. "It's been ages. - Really capital performance last week, by the way. Fantastic stuff." A particularly satisfying win, considering. "I've been very pleased to see how well you're faring. Draco always said you were awfully talented."
Probably he'd said something to that effect, anyhow, even if Lucius couldn't really remember it.
