Meat was found in the food served to the Brahmin priests. The question is: Who did that?
Was it Rekha, or Suman, or Rannvijay or Dr. Surbhi (whom we have been reliably told is Siddy's sis)?
It looks like it is not Rekha. Why? Because it seems she is unaware of who did it except that she is happy that Laali has been publicly humiliated. Rekha believes that Laali is getting her just rewards for having done the same to her.
So it leaves the other three.
Will the CVs ever tell us who did it, and why? Or are we never going to find out?
We can figure out the "why"? But the "who" has mystified us?
