It doesn't take Kaine very long to work his way from the rooftops to the ground floor via the building's ventilation system. It takes him a little longer to reconnoiter the hostage situation: how many henchmen? what kind of weapons? where are the hostages and where are the exits?

It takes him just a little bit longer than that to seize an opportunity, when the stressed out failed armed robber is looking the other way, to drop silently to the floor between two of the hostages. He holds a finger to his lips and looks around to everyone who can see him... and then punches himself in the mouth, hard enough to draw blood.

Won't be long until one of Peter's do-gooder friends shows up, Kaine thinks. I'll just sit here and make sure it doesn't go pear-shaped before they get here. Just. In. Case.
