Cal decides to have a cigarette after all. When you're not sure of what to do with your hands, it's best to keep them busy. He takes out his pack (in the same pocket as his laserpointer, not that that's going to do him any good - even if he could get to it in time, killing this soulless Sherlock would be as good as killing the real thing, since it would leave nowhere for the soul to go back to) and extracts a cigarette.

"It did occur to me," he says evenly.
