Severus gets the other one, easy, and for a moment just surveys the scene, five incapacitated people - the two who are disabled versus stunned still attempting anguished, furious communication - before he zeroes in on one of the men from upstairs. He grabs him by the front of his shirt and then drags him back into the kitchen, away from the front room and the windows (curtained as they may be) that face the street. (Not that anyone can hear or see much, from outside, with the sealing spell.)

The man is deposited unceremoniously on the floor, back against the kitchen cabinets, while Severus pulls a glove out of his jacket pocket and onto his left hand. Ever since facing Bellatrix, the Dark Mark has burned (first to charring), and it still gives him some discomfort - hence putting a layer between metaphysical connectivity, now.

He doesn't bother telling Lucius to keep an eye on the rest of them; that's what he's here for.

Severus drags a kitchen chair over to sit on, and then grabs his victim by the neck, forcing his head back and meeting his eyes. He speaks no spell, but the sudden full-body twitch that the muggle man suffers despite the stun that grips him is evidence enough.
