But in my opinion I don't think it will happen. The Nidhi and Ruhi twist will be revealed and the marriage will be stopped/postponed/called off for the time being.
I can see only one major reason for this and that is to explore the scope of Shagun's character turning completely negative. She will try her best to get Raman and the family back and keep Ishita away from all.
My only confusion here is that shaadi might happen but at a later stage and definitely not now.
P.S- Ishita deserves better and she needs to stand up for herself and slap Raman. He cannot be treating her like a piece of garbage. In that sense atleast Shagun shuts him up when he acts smart with her 😛 😆
