Well thats why the brothers are enemies...Armaan knows his side of story and Veer knows his side, both dont know the other's POV...but kavya played with both and only she knows the full version...
And then I guess there will be a part where under kavya's mind control or/and as newly turned bhediya Armaan went wild for a while, killed people, forced things on Veer....and then he came back to being good boy again...I guess that part he didnt clarify to Esha...Koi nehi, Veer bata dega abhi if/when they explore a Veer/Esha relationship...😆
