Don't worry everything will be fine. This what might happen. At the end of the episode we saw Nakku has come to the Lion's den. The lion will roar a bit - probably ask her to leave. Nakku would leave the PN to cross paths with Salman Khan. In the meantime Baaji would come to Dutta and let him know about Kala's harsh words to Nakku making her feel not worthy of Dutta. Dutta would conclude no wonder she was so aloof and avoiding him. He will understand her reasons for running away at the time of the proposal. Dutta and Baaji would set out looking for her. Salman Khan would reunite them and by the end of Monday epi Nakku will be back to the PN. Dutta will reassure her that her status or looks do not matter to him. Both Dutta and Nakku will then open their vrath and hopefully Nakku will say yes to his proposal.
I think the face revelation will wait for another day - I am hoping a mega episode on a weekend. Maybe in the beginning of Oct. In the meanwhile wedding preparations and ceremonies will start and lots of Tasha romance.
