I agree this show is great and all the cast are doing a great job.
Durga 's concern is genuine and she knew what she as going to do when she met up with Shaurya. She was ready to challenge him to go ahead with his meeting with Payal
because Dayal had told her that Payal's reaction to the confrontation just might be good for her.
And when she did that the coward that Shaurya is he ran from there.
Dayal too has a plan to keep Shaurya on his toes by showing his displeasure of his daughter being in Shaurya's company.
Both Durga and Dayal are making great moves to irritate Shaurya and the Goenka's.
And you are right Shakshi's expression for her rotten son was a mixture of disgust and impatience at his dumbness.
