The DNA report shows Aarav as Arnav's son, and to prove the paternity there is nothing more authentic than the DNA Test, yet the first thing he says when Khushi shows him the DNA reports is that its not possible.
Though the discussions on the various FB pages, forums, blogging sites etc has been is Aarav Arnav's Son or Not because of the way things were executed, they were sure that Arnav Singh Raizada is not a playboy, he is not someone who would sleep with a woman and then forget about it, so definitely he can never be Aarav's father.
Well Arnav Singh Raizada also says the same, he walks up to Sheetal asks what and when not because he cannot remember but because its insane that she was accusing him of something he has not done and was not giving him a chance to clarify things by talking about money and custody etc when clearly what he wants to know is why she is doing something like this.
We know an Arnav who was ruthless, who tortured Khushi almost always, who in the heat of the argument hurt his sister etc, but never have we seen an Arnav who is Heartless…..Yes he tried to be that guy, but the goodness that was left of him never allowed that to happen.
Arnav sure is confused as to how the DNA report says positive, as to how Sheetal made such a statement but his conscience is clear which is why hopefully one will get to see the truth about this entire track in the upcoming episodes.
The latest promo of IPKKND does say that the truth will come out on 9th November 2012, but one would have to wait and watch to know if the truth will be out as per schedule.
