Vikram almost got a heart attack. He knows his dad cheated. Unless Vikram realises what ranisa is upto he would not know how to react to this situation.
Rani might think Vikram is upset because he did the accident.
Did you see the episode?
I also don't understand this cheating thing. Didn't this happen before Ranisa-DV got married?
Agree with your thoughts, Rani might think Vikram is upset because of the accident. Everything is tying together now hehe.
