During their eye lock, I could see many emotions yearning, desperation, confusion,shock and more importantly love. They both subconsciously love each other very much but the matter got out of control. Ishita wanted her husband to stop her and he wanted to interfere but without evidence he was helpless. She looked back and he opened his mouth slightly as if to object. Emotional episode and Divan nailed it superb.
Both Bhalla and Iyers families want to take matters in their own hands due to their pride and love for their own kids, that they wouldn't allow Raman and Ishita to voice their opinions or stay together as a couple. Raman and Ishita were like Romeo and Juilet stuck in war between both families.
P.S. Raman bashers, he believed in his wife and is willing to prove her innocence. Some of us didn't bash him because we knew our Raman very well.
