Ishita will be Ishita, she won't change ever. Some were under the impression that she stood up for Raman. Well, now the happy dream is gone! The conversation she had Toshiji explained how she's as a WIFE. In stead of telling the real reasons behind the fallout, she accepted Raman's the reason. She also concluded Raman's EGO is the reason of leaving Bhalla house, wow! If this is how a WIFE stands up for her husband when he's innocent, then there's nothing to say! There is a word "two-face" in the dictionary to describe for these sort of people.
Raman was at fault initially, he raised his voice against his father. He left his home thinking about his wife and son's honor. Yet, by becoming a Joru Ka Ghulam, he failed to earn some brownie points from his wife. Ishita will always be a mother, bahu and whatnot first but never a wife. And, when she will try to act like one, then suddenly she will behave like a two-faced in the next moment. Deny if you will but IshRa as a couple should not have happened in the first place.
