As revenge, Ranjith and his gang kill Professor Varkey's animals in his lab, which makes him go mad. Ram and Ranjith wind up in a bathroom alone together. Ranjith throws himself into a mirror and beats himself, claiming that Ram attacked him. Trying to clear things up, Ram visits Ranjith's mother at home. Frustrated when Ranjith still plays the victim and his mother will not hear Ram out, he hotwires Ranjith's car and drives it into a wall.
