If not, she is giving Adi a false hope. She is making him believe that his parents are happily together. Sooner or later Adi will get to see the real picture and that will be more destructive from him. Maybe the tiny bit of hope to see a reformed Adi will be out of the window by then. Any sensible woman would figure that out very easily. It's very disturbing to see Ishita, as a doctor, is oblivious to the reality. As a medical professional, I'm perturbed at the CVs to show Ishita this much dumb that she can't think clearly even when it's related to her professional area.
Toshiji had advised Ishita few days ago to maintain some distance from Adi. Forum members didn't like her advice and Ishita never listens to anyone. But once again Toshiji proves that with age comes wisdom.
