In part three of the video (I don't speak hindi) my interpretation
Kaveri went to the photo shop where she found out about the photo. She went to the village and she found the guy that was pretending to be Saloni's husband with his wife crying.
On showing them the photo the wife started to cry and beg Kaveri for her children.
She then told Kaveri all about the plot of Nahar and Saloni having her husband pretend to be Saloni's husband(this was shown in the flash backs with Nahar, Neil and Saloni in the Rajstan tent).
The episode ended on Kaveri's facial expressions.
Precap is Neil and Nishi
