Malcolm has been expecting the move, and pulls the trigger as soon as the man flicks his hand.

Nothing happens.

He glances at the "screwdriver" in the man's hand, then back at the pistol. Somehow, this... thing disabled his weapon. And it might well disable him next, quite literally if he's unlucky. Which, in these situations, he tends to be.

"What do you want?" It seems like a reasonable question. After all, the intruder has all the advantages.
