Radha is the one who is feigning innocence, naivety or ignorance. Definitely not Gayatri! She is conspiring secretely with her, son Aakash and Ishita to assume full control of Scindia's enterprises. Once they are successful in their collusion in plan and Radha is crowned joint monarchy with her son, Aakash, all the Scindias will be evicted out of the mansion. As for Ishita, she and Aakash are apparently secret lovers behind closed doors and using a charade of lies and deception fool the Scindia's. Assuming that Aakash is her biological son when he is indeed Radha's Gayatri is avenging Radha and Suraj by allowing Aakash to be contemptuous towards Yash. We ought to remember that it was also Yash's decision to have this sort of treatment to be meted out to him.
