I'm talking about one scene of Bāhubali 2: The Conclusion. Let me introduce that scene. When Kattappa was made convinced to kill Amarendra Bāhubali, one person went to Amarendra Bāhubali and told that Kattappa is being punished on the basis of Rāja-Droha(insurgency). After Amarendra Bāhubali saved Kattappa, some fighters attacked them and we all know during (fight is going to finish though) the fight, Kattappa killed Amarendra Bāhubali.
I want to know who are those attackers? Are they men of Bhallāla Deva i.e., was this fight planned by Bhallāla Deva? I'm asking this because according to scene, after some time, Bhallāla comes and says Kattappa that I suspected you only in vain. You're actually obeyer of mine.
So, I think it might be attackers planned by Bhallāla Deva to kill Amarendra Bāhubali if Kattappa doesn't accomplish his duty of killing but simultaneously looking at the appearances/dresses of fighters, they looked like attackers of other kingdom or not the men of Bhallāla.
So, I can't exactly judge or identify who are the attackers attacked on Amarendra Bāhubali and Kattappa when Kattappa killed Amarendra Bāhubali.
