It was said veer was special cheel & cheel rajkumar.
I don't why but why I feel veer is not possessed completely , he may have a feeling that someone is trying to control him , so he behave rudely just to fool his unknown enemy to know d purpose of doing all this.
Today he remembered what sea God told meera when chandani told him something of sky, so his brain is still working . I feel he is just playing around with chandani as in precap he was looking at bani who was marrying Jai. Chandani said palace fulfill wishes , so veer wish is to be with bani.
I really want all this to be veer's plan.
