Before Harry could react to anything that Nott had said, they were attacked. He swore, rolling out of the fall that he'd been shoved into. He came up fast, sending a hex in the direction of their attacker and knocking him down; and then another one to the doorway where another one had appeared. These bastards were like cockroaches, the moment you turned your back there were more; the warehouse had been empty when he'd gone downstairs to find Nott.
There were sounds of a scuffle coming from the outer room, flashes of light at more curses and spells flying. The man in the doorway went over like a felled tree, the crunch of his nose breaking as he hit the floor heard even above the ruckus outside.
Harry needed to see what the hell was going on in there, so he pushed himself up and edge towards the doorway, gesturing for Nott to keep an eye out for anything.
