Sharada was trying to save Mandar's life before he threw her off the roof. Unless she's that rare mother who can just turn off her emotions, I imagine that she was trying to save Mandar's life again by telling Pallavi about Raghav's gun. Yet Pallavi continued to dance instead of trying to stop Raghav.
Wouldn't you expect Sharada to be disappointed with Raghav and Pallavi today?
Instead, Sharada put all of her effort into communicating about Manasi's phone. Very sensible, Sharada, setting aside your emotions to remind Pallavi and Raghav that your life is in danger until they take some information to the police about Mandar. Now, if only it would occur to the lovebirds that Sharada's eye-blinking testimony could not only get Mandar arrested but get him convicted too.
By the way, doesn't Raghav already have microphones in every room? Including Sharada's room? After all, that's where Mandar might speak his secrets because Sharada can't tell tales. So, whatever Sharada has recorded in Manasi's phone should have been already heard by Raghav, right?
I noticed that Mandar's blackmailer's name is Akshat. Just before Sunny hit Mandar with the car, Kirti mentioned the car belongs to Akshay. I wonder if there's a connection.
