They're just about to the lobby, when Natasha stops. She reaches out, grabbing Clint's wrist as he does, too, and pulls him down the hallway that leads, presumably, to a laundry room, if the smell of fabric softener is any indication. Not that that's important. What is important is, "They're going to start letting people back in, soon."

So, maybe they should wait here and then slip out through the crowd.
