In this case something came to my mind I think aftr torturing krishna prats will cum to knw that angad was her enemy not krishna and will also realise that krish's love is true love....While realising this Pratigya wil talk to krish and no doubt krishna will believe her and will get mad at angad and will try to kill him then prats will stop him saying that we will punish him but we wont beat him..we'll make him confess his mistakes infront of the police and police will arrest him.
On the way of taking revenge from angad pratigya will fall for krishna
and then the love will began......I know it'll b tooooo late but thts wat it came to my mind
