The secret behind the killing of Baahubali at the hands of Kattappa was also leaked. Here is the story as per the post being circulated online.
‘After defeating Kalakeya and his army, Baahubali becomes the emperor of Mahishmati kingdom. Bhallala Deva and Bijjala Deva keep looking for an opportunity to dethrone or possibly eliminate Baahubali. One day, soon after seeing Devasena of Kunthala kingdom, Baahubali falls in love with her. A jealous Bhallala Deva also loves Devasena and sends marriage proposal, but she rejects it.
When Bhallala Deva complains to his mother, Rajmata Shivagami, that he had earlier snatched the kingdom and now Baahubali is snatching Deva Sena as well, she asks Baahubali to choose either Devasena or Mahishmati’s throne. Baahubali chooses Devasena, marries her and leaves the kingdom.
Once Baahubali leaves, Bhallala Deva becomes king and he starts treating people with contempt. Soon, brother of Kalakeya, Ninja, attacks Mahishmathi and kills half the force. After Sivagami seeks help, Baahubali returns to Mahishmati along with his pregnant wife and save the kingdom.
Bhallala Deva fears that if Baahubali wins the war, he will once again become king, so he orders Kattappa, who is loyal to the king, to kill Baahubali. Under the oath of obeying the king’s orders, Kattappa kills Baahubali, feeling guilty of letting Baahubali die, Sivagami saves his infant child and manages to hand him to tribal people by sacrificing her life. Deva Sena gets jailed in Mahishmathi. The flashback ends at this point.
Next, Sivudu, with the help of Kunthala force and Kattappa, kills Bhallala Deva and frees his mother, Devasena’.
