1. Karthik thinks Singhania and Maheshwari have forgiven Mansi. If this happens it is going to make him look dumb and two faced, because he himself hasn't forgiven Manish and Suvarna who were indirectly responsible for his mother's death, yet thinks S and M families will forgive Mansi.
2. Naira think Karthik is talking about Kashayp and says something about jail.Karthik thinks that Naira and the family wants Mansi to be punished and sent to jail. We know that Karthik and Naira will have a joint dream of zalima, so showing that he knows that his sister is going to get jailed yet he is busy romancing in his dreams, will make him look like the worst brother ever.
Both these ways would lead to Karthik's character assassination.
3. Naira knows Karthik is talking about Mansi. She says she won't forgive Mansi and next moment she would be dreaming about zalima. That would again be out of character because she just got to know the truth of her mother's death, so how can they show her wanting to romance.
4. Everything is solved and Mansi is forgiven before the wedding. But this is impossible because the wedding has only few hours to go and such a big thing getting solved so quick is impossible.
But what if Akshara's death didn't happen because of an accident. I vaguely remember there was a scene where police inspector that lot of robberies happen in that area. What is Akshara was only minorly injured by accidents, just a couple of wounds that would get okay by first aid. Then when she was going towards the car she was caught by the goons, robbed and thrown off the cliff. So maybe the police catch the robbers and see Akshara's phone and ask from where the got it and the robbers tell them.
So either the police phone and inform Singhanias about it. Karthik and chachu over hear. Chachu tells Karthik that he wanted justice for Akshara by telling the truth but Akshara has already got justice and talking the truth would only bring a dent in relations and ask him to keep mum.
Or Karthik informs S and M families, after they get to know that Akshara's death was due to robbery, or he informs them before they get to know, everyone's angry, police inspector calls and informs of the robbery. At the end S and M families think whatever happened was for the good because at the end Mansi was innocent, and if they as well knew Mansi was in the car they would have punished her and later when they would have got to know the truth that it was actually the robbers work. They would be guilty and relationships would have been ruined.
