Severus takes the suggestion to ask the others as another hint that he should give up his charade and promptly goes quite deaf to it. Instead, he mulls over this roster he currently has: two Malfoys, Narcissa, Rosier, Dolohov, the Lestanges. And on his side of things, Granger and Xenophilius. Likely straddling the fence is his doppelganger.

Even if the Lucius before him is reformed, Severus is outnumbered. Vastly so. After a long moment, he gives a thoughtful nod. This is enough to be getting on with for him.

"If you'll excuse me, I have other matters which require my attention." Such as ensuring the cavalry isn't sent to rescue him. He has the information he needed, and has never been much of one for socialisation, anyway. Later, once he's had time to consider his next course of action, he'll invite Lucius out for dinner. Or something. Drinks. Bemoaning their lot in life. The usual. "I am most obliged for your time and candor."
