Once safely downstairs, Narcissa opens a bottle of wine to keep her company while she puts something together in the kitchen; something simple seems best, both for the sake of being quick and because she's not sure if he's up to anything too rich or heavy. There's fish, and it'll only take a half hour or so for parcels she can put tomato and capers over, light enough that she can eat a bit too (it'd be so awkward to make him eat alone) without being overfull.

She allows the details to distract her, and by the time he's done, there'll be food (she prepares it, serves it, and then casts a charm over it to keep until he's properly done - she doesn't anticipate him being in a hurry), wine, a pitcher of water on the table in an unsubtle hint to drink it, since he could probably use that too, and the lady of the house standing at the door out into the back garden, smoking.

It's not one of her better habits- but Merlin take it all, this night.
