There's a moment when Antonin first steps in, in which Severus looks momentarily busted, a small echo of the reaction he used to have when one of his seniors caught him smoking at meetings. But it flickers away in an instant, and he ends up just looking bemused at himself. Antonin is, he feels, fairly low on the list of people who might be scandalized that he's sitting out here smoking a joint and forcing himself to eat.

Permitting pizza thievery without objection, Severus sets his book down - legends of the city, something that looks slightly more fanciful than factual.

"Getting thrown out earlier and earlier, I see." Of bars, of course; but his voice is subdued, not actually thinking Antonin's been up to any great efforts in that direction, today. But they aren't the sort to say How are you?
