1- If there has to be a triangle then this triangle is better than Dipali, RK, Madhu's triangle any day.
I see people saying they don't like to see a triangle. But aren't we seeing a triangle even now, that also a disgusting triangle which involves a devar and bhabhi. One is flirting and BBBing his bhabhi and the other one is seducing her dewar every chance she gets.
2- With this new entry, we are going to see Trishna's real face again. I can't digest her behaviour nowadays. I am sure once this man falls for Madhu, again Trishna will get angry. Whether he is a don wouldn't matter. Money and power matters for Trishna. So another admirer for Madhu won't go well with her. That also a powerful one.
3- At this time an entry is needed to progress the show. Otherwise, it is either we have to see Madhu being humiliated by RK on the set everyday, or Rishbala patchup and Madhu cooking at RK mansion everyday. Obviously this won't work if they are targeting for 1000 episodes. There has to be story and CV's are now scared of the turn of the big twist where most of the people thinking RK as the villian. So before it goes out of hand, they are getting a villian in the show and will make him, a more cruel person than RK.
4- About the child, articles says Sultan has a son. Articles said RK spike the drink, but Dipali did. So who knows it is his son or his kid brother or some relative's child he looks after. Possible.
5- Avinesh is a good actor . A new one only one show old. And I don't think he will also accept just any role. He has done a lead role before. So this role would be interesting and he would be the first don of television I think. That also a young and handsome don. if they brought a new character as a junior artist or a hair dresser, then what happened with Mukku would be repeated.
And from what we have seen in the show, so far CV's always give priority to RK's character more than even Madhu. So RK won't be sidelined in the show. And neither MB will be from now on, because they have seen the result of sidelining Madhu and giving screen space to Trishna in the initial episodes.
