After letting the first arrow sail toward the man, Wolff was already notching another to fire again.  The thug dives and narrowly avoids a fatal shot.  Wolff is surprised at the dexterity that this man displays and aims the next arrow for the chest.  It flies but strikes pavement as the man who is most likely his target rolls forward toward the fire escape.  Wolff knows once he hits the fire escape the closer quarters will make his bow much less effective.  Wolff begins running down the stairs with the audible sound of the fire escape swaying back and forth with his momentum.  Wolff takes a smoke arrow and quickly fire it toward the bottom few steps.

Wolff's plan, if he could find the opportunity, was to use the smoke screen to keep his distance from the punk below him.  The smoke would bellow out and give him the chance to either jump down from the fire escape or simply catch the would be attacker off guard.  Either way it was better than letting the guy get to the stairs and use them for cover as he closed the distance.  

The Accountant's briefcase remains seemingly empty at the top of the stairs while the few vagabonds start to leave the alley in fear of being caught in the crossfire.
