It's just an argument normal difference of opinion and freedom of expression by all 3, as it is cvs are unnecessarily making shivkara fight
They are family it happens
And I don't think rudra was so wrong as well
All 3 are right in their own way
Shivaya thinking from reputation point of view which is practically important
Omkara thinking from truth point of view
And Rudra from an innocent boy point of view who still has to step in the cruel world who believes his family to be true thus is emotional but at the same time can't neglect practical aspects of society
He is confused whether to be emotional about family like Shivaya or rational and question why repeatedly things are happening with their family? Are they wrong anywhere?
But as Shivaya is his ideal and he has seen him coming out of situations by winning over it he is following him as he can't see his family getting affected.
