Marc chuckled at the instantaneous reaction that spring from Matt's nervous system. It was a good reaction, perhaps a tad over played, but it would've been the proper thing to do on a dark night in a sketchy alleyway. Marc had never done that because his reaction speed had always been fast enough to block a punch or kick when it came at him without putting his hands up. Clearly Matt knew about martial arts, and did them because he recognized Marc by sight. He called him master too, Marc thought it was funny, knowing it was a joke he laughed. 
"Just Marc will do!" He boomed, then got into a conversational tone. " I just came from te sign up station for martial arts, looks like a lot of competition. Haven't heard any of the names though, was yours on there?"
