Avdesh asks G what is the farak betwen hin and Rana during the clandestine meet, and then next scene he tells Rana that he knows the difference now and apologises, and even wants to die.I think he has hit the bottom of the pit, will he come back with a change of tactics or does he go into depression, unfulfilled obsessive love.
Either he comes back more wicked or becomes so apathetic that his sister gets into action. Either way he is here to stay. And the saazish gets more murkier.
