Sultan has declared that he would fight RK to get what is supposed to be his. RK, who has been waiting for such an opportunity, has jumped at the chance to fight Sultan. The winner's trophy being Madhu.
When Sultan calls Madhu and asks her to come to him, he knew what to expect from Madhu and RK after the call. He knew RK would come and not Madhu. The same would happen too.
After the call, RK notices a change in Madhu and would ask her what exactly Sultan has said to her. Though Madhu hesitates a little, she would eventually tell everything about the phone call. Sultan would have said that, RK has snatched everything from him, his soul, his heart, his happiness and his Madhu. And he wants what is supposed to be his back. This would not sit well with RK, the fact that Sultan thinks Madhu is a part of his destiny, in particular.
RK, the next morning, decides he can't have someone thinking of separating him and Madhu, and he cannot accept this at any cost. He decides to put an end to all this and goes to Sultan with a gun. Sultan too is prepared for this. Sultan would have also made Dips send Madhu to the place of duel.
We have to wait for today's episode to see who would kill whom, who would win Madhu and who looses her forever.
Also the precap shows, Madhu being at the gun point. Would she be shot in this RK and Sultan's duel? We have to wait and watch.
