So now Shagun has one more shield in the name of Ishra kid (embryo) to get Raman dance to her tunes. If he doesn't agree to her terms, she will give him the Dhanki that she will harm the child in her womb and Raman will get Mihir released even the police prove him to be the culprit as Raman want to see Ishita happy by having her child. But will end up with loosing the whole family in the bargain. He will just be murmuring one phrase to Ishita "You have faith in me right"/ and to hell with his cry baby avatar yet again. But believe me, he will not even utter a word to Ishita or his family about the surrogacy and Ishita's child being grown in Sahgun's womb.
She (Shagun) may even blackmail him to keep it as a secret for the time being till Mihir's case is resolved and by then it will be too late for raman to tell it in open as either his wife nor his mother will be ready to accept his explanation. So he will separate from his family and just to get hold of his child (Ishita's) in his hand, he will take utmost care of Shagun and then bring up the child alone without anyone's help except Shagun as she has blessed him with his child.
