I think retorting Saagar back is a good way to play this. It is much better than having ghosts moving around in the Singh Mansion..not there aren't enough of those. In this manner Sindoora will be more of her true self, because she won't feel threatned by Saagar.
For once it will also be good to see a Saagar and Vidya working together to one up Sindoora. I've always wanted Saagar to be Vidya's ally and it has finally happened, and I think it will be interesting to watch. Dulhann has really taught me to be patient...and I'm looking forward to the upcoming episodes..to see Sindoora harangled for a change...
