Yeah, I also think it might be Ranisa and there is no bigger mystery. Ranisa thinks very highly of herself.
In the episode when Veer yelled at Rani in front of the entire family, Rani said "what if your Ranisa were there instead of my Bauji?"
The camera was focused on Ranisa, she was shocked/scared and clenched her hand. That scene + DV talking about her mistake made me doubt her. However, they might be forshadwoing another mystery, because I don't think DV know anything about the accident.
Nandini's DL might be a distraction for the audience. Just like Ranisa-Vikram scene.
Oh yea, thanks for reminding about that scene. You are right. She had very over the top expressions there, I even commented on it I think. Then it would make sense if she is the culprit.
I too think DV doesn't know anything about the accident. I think what DV mentioned was some past thing.
Mhm true. They might have done it to make Nandini look suspicious too, so that audience can't figure out who it is right away.
