By the time the truth is known Kutty had already declared a duel with Kunjali, his biological brother who had threatened his villainous adoptive elder brother Ithiri. Kutty is torn between his loyalty to his adoptive family and his biological family who have truth on their side. Ambu makes his way to the fort to save Kunjali from the duel.Kutty makes sure that the magical amulet reaches his aunt who will restore it to the rightful owner, Thacholi Ambu.
