Kahl's pace quickened as he continued making his to the source of all that din.  Only to stop when he heard loud noise and man's voice shouting. His attentions changed as he honed on to new objective.  From what he saw there were two men, one beefy and very pissed off, and one not so beefy guy at the receiving end.  He pondered what to do but his racing instincts got the better of him and before a thought even completed itself he found himself hurtling a decent sized piece of debris at the skinnier guy.  Either it would hit him or it would prove a useful distraction to allow the other guy to get him. It didn't matter what happened. All he knew is his gut was telling him the beefy guy was the not bad guy in this situation.
