I have no spoilers! 😆
But it is obvious that if they want to maintian the smart RV they would show him going back to the basis of why Ishaani would pretend memory loss and get to the bottom of everything himself. But he would act as though he is angry with her just to protect her with the question of what if the bullet was meant for Ishaani, but we should not expect the writer to be too open about that it would spoil the fun of the suspense if that is what they want.
RV can also be every well believing the worse and angry as right now he is not even worried about the baby been dead or Ritika to me he is more worried about the fact that Ishaani and ISK were in all this together and she did not trust him enough to tell him everything right from the beginning and had to result to ML drama from the written update so from RV perspective it is a jealousy rage he is acting on not that he believes truly that Ishaani is capable of what she is been accused of and when his head clears and the jealousy goes down hopefully he would start asking some sensible questions.
