Rodney was out of the kitchen, down the corridor, and began to make his way towards the office and the equipment there. Schematics... where were they? The lights turned on, the lead researcher was just beginning to settle in to the desk there when the gunshots went off. His head jerked up, and rising from his seat, reached towards where a pistol would be, if he had one (and a holster), and finding that he did not, paused.

Gun.
Unarmed.
Brilliant scientist.

Still, there were others, and reacting more on instinct than on self-preservation (which will certainly come later), McKay bolted out of the office and headed down the corridor back towards the kitchen at a speed that one sees only rarely.

No more shots. But the screaming?
