After today's episode, I feel that Viraj is not out & out a negative character. I don't know whether the CVs had thought this much. But, to me, it looks like while agreeing with Anu to marry Prerna, Viraj had his own agenda (regarding the baby) and it is later on that he had to join hands with Sonalika. It is my guess only. What I feel is that CVs might later show that, after Viraj happened to hear Sonalika's convo with Ronit on the day Prerna was kidnapped, he might have reached an agreement with Sonalika to not harm Prerna further. His act with Jagga in the shopping mall might be only an attempt to not let a third person know about his agreement with Sonalika and his motive behind marrying Prerna. That will justify all his actions and words on why he was shown restless when Sonalika informs him of killing Prerna on the way to engagement Venue. That very moment he advises Sonalika to be patient till he marries Prerna to which she replies that she can't be patient anymore. The reason why he can't sternly object Sonalika against killing Pre might be because, he is afraid of Sonalika exposing him or maybe Sonalika is using his wife as a pawn to control him. But his words to Sonalika not to be delusional & to better accept that Prerna is not going to love anyone other than Anurag; and that is why he had decided to trap Veena who is more vulnerable than Prerna plus his today's words to Anurag to be aware of his memory loss & to think properly before sharing Anu's beautiful & personal belongings (indirectly hinting Prerna) with strangers shows that he is basically not that evilish at heart. But it is some sort of helplessness & his selfishness arising from his love for his wife, that is forcing him to be a pawn in Sonalika's hands. And i think his wife too knows all the truth and it is with her knowledge that he is marrying Prerna, which clearly means it is something related to cutiepie.
I am really happy today that, it is after a long time I am getting to do some guesswork on a KZK character. Thank you CVs for bringing that suspense element back in KZK. Hope you will not drag it again & one fine day scrap the whole plot illogically with the help of a knife & mask. We need a proper tashan & closure between Anu and Viraaj just like how it happened in NB track.
