But once it is known to Ishwari the real breakdown of Sonakshi starts. It is like a slow and painful death where you lose a little bit of yourself everyday. We will see Sonakshi breaking little by little every time someone taunts or says something harsh to her.
This slow death is what will make Dev speak and stand up for her. He won't be able to tolerate the crap that is dished out to her. He cannot see Sonakshi in pain. We will see the Dev we always wanted to see in the upcoming days.
Just my POV
