Vyom....

Honestly speaking if anyone has been following the story or let's say Vikram's interviews too ...then at the very start...he said in an interview ki promo dekh ke to mujhe bhi laga ye humari love story ke beech mein aa gaya but aisa nahi hai you have to watch the show for that...He said there is more to his character than be a lover boy...so when hey are showing his story why is everyone shocked...I always thought it looked on the ways of Raaz like the good guy being the shady one and well here he is...

Yes, part of "psychological thrillers" or mystery dramas are about what clues the audience catches and how they interpret them. For sure, there were many instances even before and after the possession drama where Vyom was shown to have little slips in his composure. There were a few times where he acted out, he just managed to cover up and much of the audience took it as "he just loves her a lot."
