As much as Varun's death at the hands of Rudra makes the story intriguing, his being alive will add another layer of complication to this tale. Esp. If Paro and Rudra believe he has died whereas he has escaped in reality. And he comes back later to get his wife back, Rudra will be burning In J. As if they needed more complication
Yes thats why keeping Varun alive will make things interesting for future .. like u said Rudra and Paro might assume he is dead but in reality he escaped leaving his wife alone ... so then in future whether he comes to take his wife back or whether Paro and Rudra finds out he is alive and Paro deciding to go back to him will make the tale really interesting ..
