Combeferre has no idea why the room is apparently called Vous. Is this another statement of royalist or aristocratic allegiance, perhaps? Another teasing jab from Bar?

...and it is, in fact, extremely blue. There is a single blue round bed--at least, it must be a bed, though it looks more like an overgrown pillow thrown on the floor--which is a particularly dark and intense blue. The walls have some sort of light blue floral design over darker blue. The chairs are a sky-blue leather. The lamps have a blue pattern. There are one or two pink objects, but it's mostly just blue, blue, blue. Relentlessly so. At least the barricade's flag would stand out properly against such a background--but that sardonic thought isn't an actual endorsement.

(Given Bar's previous choice of rooms, Combeferre also has a niggling suspicion about what she's implying with the sole bed. It would be wholly ordinary and innocent for Enjolras and Combeferre, as for anyone of their time and place, and Bar likely knows that, but--well. Combeferre has read things that imply that future times and places are different in this regard. And Bar evidently likes to joke. Well, let her; it does no harm.)

"Well, we would match Joly and Bossuet," is all Combeferre says, dryly.
