Jack was tossed against wall. It would have left a mark if not for his suit. He watched the Serenity as she struggled. He followed her with ease as she tried to get away. "I'd say your making things difficult but I can walk faster than that." Jack said as he began to catch up. "If your so intent on running then I might as well do this." He said as he pulled out a pistol armed with concussion rounds. He began to shoot at Serenity. If the concussion rounds hit her then she was in for a world of pain. "You are about to learn what it feels like to get shot. My previous shot didn't work out too well but things happen." Jack let out a sigh as he kept shooting at Serenity. "Go ahead and scream...I mean, if you can squeeze one out. You know what's above us? Atleast 6 feet of concrete. Your friends won't here you. If I'm right we are far from where they were anyway."
