Firstly because the entire Rishbala interaction seemed full of "saccharine" sweetness...to put my sentiments about this moment into words, I would say I felt as if I was sucking a sugar coated pill...expecting that very soon the sweetness will be replaced by a bitter taste...
Is it love that has brought Madhu back, but whose, is it her's for RK or RK's for her which crosses the heights of obsession?????
Also don't think seeking revenge is the underlying motive...
Another pre-sentiment of mine is that though RK is at ease now that he has got his object of obsession besides him, he still has elements of doubt...
Another reason that made affirmed my hunch is that Madhu bearing the brunt of her mother, to the extent of being disowned by her...
Padmini's outrage is definitely justifiable not only because that her usually confiding daughter has hidden truth from her but also lied to her...and lied for a person who had severed all his relationship with her and left her asunder...
Until the motive of Madhu's behavior is unravelled, let's just enjoy the way this story is forming up...
Leaving with a Bon Jovi song which made me wonder the latency of Rishbala's relationship :
Shot through the heart
And you're to blame
Darlin'
You give love a bad name
An angel's smile is what you sell
You promise me heaven, then put me through Hell
Chains of love got a hold on me
When passions a prison, you can't break free
