In a serial that already had an abundance of unfinished tracks, K's infertility track has opened a lot more possibilities. It has led to a complex web of misunderstandings, conspiracies and break ups. Pratigya's resolve to keep K's secret under tight wraps is doing more harm to kriya relationship. But the million dollar question is whether K's infertility is a reality. I don't think so. We all know that Krish is in a lead role and there is no way CVs would like to show him sterile forever. If his reports are correct then as all the doctors consulted so far have ruled out his chances of becoming father. So, in case K is ever going to father a child, we are left with the only option that his reports are wrong. It could be due to mixing up of samples by the pathologist or might be the conspiracy of someone else. So, assuming K to be fertile, it is P and not K who is in the dark. Pratigya's ignorance may lead her to commit grave mistake of remarrying Krishna. The truth that K is not infertile may come out in the open when P herself or K's second wife will become pregnant. But it will be very late by then. P may hv to face a very tough time out of her own fault only. There will be a lot of scope of PBJs as CVs always tend to keep the story pratigya-centric.
I'm almost sure that K's reports are not correct and this is the only way that keeps us waiting for kriya baby.
