It was perhaps the first time shoe was on the other foot and I must add Raman failed his test miserably as quite clearly his disappointment jealousy and disturbance on hearing subbu name from ishita was quite clearly evident and open and it literally set his pants on fire
Raman is a silly guy as he was even jealous of his own daughter Ruhi for amount of importance she had in ishita life well I had heard love makes ppl go blind but in Raman case it had made him go irrational to the level to make him jealous of Ruhi
Raman in his last conversation quite clearly was relieved that subbu had faded out of her system but was mightily disappointed that he was not engraved in her system
Raman is so affected by loveria that he forgot the deal for this marriage that was Ruhi and he expected her to be happy because of him haha
Raman is extreme version and it is clear he has become extremely possessive about ishita and has sense of ownership about her
Ishita might say she is over subbu but quite clearly she will get the shock of her life when he walks in
I think karan was fabulous in last scene where he portrayed Raman hesitancy disappointment and heartbreak perfectly
