Years later, a penitent Aparna, who now worked at a charity school, runs across Adheena's son Abhimanyu, who was a pupil there, & who was now being raised by Yatheendran. Her tries to bond with Abhimanyu are rebuffed by Yatheendran. At this point, Abhimanyu's biological dad shows up & claims him. (Summary by iceblox)
