[Jack moves, and he moves fast. He doesn't turn when he hears the small explosion, and shouts where there had been quiet voices from the hall. He's out the window in a few short moments, then there's a short sharp stop as he drops to the fire escape a floor below, grabbing hold of the railing edge to keep from making noise. Then another drop, and then he's on the ground, moving fast.]
No sign of anyone. [He's still running, down a side alley, weaving over two blocks to where his bike is parked. With something like a smile, accented by the adrenaline rush.] You're not halfway bad at this.
