I don't see how the doc wouldn't have recommended some further tests or some course of action that may be required, she was a waste of space anyway. Even though we have to assume that K had his sperm tested, you don't just blurt out something like that without some advice on where to go from there.
I feel P'll tell him eventually, maybe when there's an upcoming ME, they might get a 2nd opinion and K'll get treatment.
BUT, if Meera's behind this, she'll get caught out, K'll want to kill her, P'll want to kill him for not telling her, but the bottom line being, Kriya will have their baby😊
