Sirius ducks into the kitchen and manages to find two relatively-clean cups, which are just about the only dishware in the entire place except for the big jar he uses to carry coffee back from the Compound. There's just enough whiskey in the bottom of the bottle for about a finger each, and Sirius carries the two cups back out into the parlour and passes one off to Granby.

"I'm thinking saying bottoms up would seem a bit crass just now, but, well…" He salutes Granby with his glass and knocks it back.
