The dealer longer when he holds Jake at gunpoint. Jake starts laughing and pushes the gun away from his head. He then asks the dealer and his people if they had ever thought about what would happen to the children who bought their drugs. The dealer wants to know who cared about that in the first place and when Jake explains that he did, the dealer asks if he was a social worker. Jake explains he was something similar and admits to being a cop. Everyone around starts laughing because they think Jake was kidding. The dealer then gets up, approaches Jake and tells him he was alright and people like him were almost welcome around there. However, Jake makes sure they know he was not kidding and shows his badge and his wire which he then uses to let the others know there was no need for backup because he would take them down all by himself and the fight begins.
