Krishna told Prats why he couldn't blurt out the truth. He is confused and took her away to figure out what to do next.
I see an interesting angle to the story here when SS and Amma show up and ask him to take her to the doctor. Krishna already knows the truth about where things stand between him and Prats. Saath janmo ka nahi hone wala ye baccha........ Poor Krishna. ka haalat hai bechara ka😭
If indeed Prats goes to the doctor, when Angad's incrimination about Prats spending a night is told, Krishna may already know the truth about the lies Angad is telling and stand by Prats when his family starts the next mahayudh. Quite possible?
