Neil and Ragini are lucky that they have got such wonderful kids. Both Suhani and Agam love them, understand them and want Neil and Ragini to be together for themselves as well as their own happiness. The difference b/w them and the rest of the idiots is that they are actually doing something to make sure it happens rather than just sitting there.
Especially Suhani, even after knowing that she is not Nachikeit's or Ragini's daughter, she is trying her best to bring the two together. What ever more endearing is that even after knowing the truth, she stills considers both of them as her parents; if anything her love for them has increased.
Now can someone please kick that idiot RK out. This is how you do it, not sit there and watch your friend being sent to the gallows.
While you are at it please deport Aarav, Ranbir, Shilpa, Pam and Nivedita on a one way flight to some distant planet. One feels for the poor planet but it is for the greater good.
