Nice post Arnav
I dont think this track in any kind of redemtion. Rk doeesn't even know what he feels for her.He is confused and very posessive about his favorite toy.He cant see her with Sultan.That is why taking her back to his house so that keep an eye on her. When Rk planned his big fat Revenge game he expected Madhu to broke completely and turned in to a female devdas.
But unfortunately this didnt happen.Infact Madhu started moving on within a week(i super liked that, go girl go).He is not able to accept that Madhiu forgot him just like that and happily playing holi with another guy. He is super pissed off so forcefully taking her home so that claim his possession rights back.
Rk is much in to the character. We have to expect this from him. He can go to any extent in obsession. But what about Madhu why cv's are ruining her character by showing her melting to his toutch. I think Madhu needs to control her feelings and stay max away from him.
