Nandini has hidden the truth because when the truth is out it won’t be one or two things but the whole thing. Karan would learn how his son had tried to choke his mother, Nandini looked on at Tulsi in the police station when Tulsi cried and said he hit me, his grandmother when I tried stopping him from hurting Vaishnavi and how he had been treating Vaishnavi. Moreover he would hear of the things that Parth told Nandini including how he wondered if she had been truly assaulted by Ansh or was she lying to get him killed by working against him in cahoots with Tulsi.
Nandini herself doesn’t know how Parth had thrown Vaishnavi off the cliff, that he had planned on selling the ancestral property and running off to US with his share. But I think eventually Vaishnavi will return to provide this part of the incident too.
Karan is being shielded from the truth of his son turning out to be such a two faced swine. But that’s why he’s hating Tulsi now. Right now he’s a father and a son who is hurting in equal measure but the father in him is hurt more than the son.
Rio was a responsibility but he wasn’t his son and the truth is Karan could be fond of Rio but ultimately the love for his own child is organic and the love for Rio while similarly organic could never have the same depth.
@bold if that is true for him, then how did he expect Tulsi to love him as his own? At least Rio is not a remembrance of his wife's cheating unlike he is for Tulsi?
In season 1, he loved Manthan and Bhoomi equally, he didn't differentiate between his biological child and his responsibility. One might say she reminded him of Nandani, but still..
Karan has always been my favourite character so it's not that I am being uselessly biased.
I can completely understand if he believes Parth was a holier than angel soul and he couldn't have killed Rio. Fine Parth fooled him, but then shouldn't he be concerned (even if not equally concerned) on who killed Rio??
For a moment I feel bad for SKY, they had him introduced with such a banger and by the end he became kind of a scapegoat whose death isn't even being given any importance.
I am not sure how much truth Nandani knows or if Vaishnavi knows that Nandani has killed Parth not Tulsi but I don't think that they should hide the basic things from Karan. Parth was forcing himself onto Vaishnavi, Tulsi tried to save her and then called Rio for help, Parth killed Rio and then (since murderer doesn't have to be revealed) Tulsi killed him..
By hiding this truth maybe Nandani is trying to save last grace of her son, or fears that Karan might not be able to accept, but is actually making Tulsi a villian in front of Karan
. I saw a bit of the spinoff epi today and yesterday’s also. I really felt bad for Munni, she was the one who brought Vrinda and Saloni to hospital and ended up losing her child
