I always knew Sagar was playing. Playing with both Vedika and Koel. As I said earlier also in my analysis Sagar has to wash the sins of his blood and Koel of her Karma. And Jhanvi is symbolic of Ganga, the one who cleanses everyone of all their sins.
So Ganga ya Jhanvi is needed to accomplish this. Aur Ganga ko khud maili hona hi hai paap dhote. That's why we see so much pain for Vedika, so much accusations because she has to suffer this pain to get Sagar, Yamini and Saraswati from that chal mahal.
She has to fight, but he will set the direction as without Sagar she cannot win. Sagar is her defense. But for Sagar it's not enough Vedika fights the battle, but he needs his defense. Because Sagar is Vedika ka defense is known, and every effort will be created to emotionally blackmail him. His weak point being Subhadra and Saraswati. You practically need one person to hold these two women in place ,to ensure they don't create hindrance. Remember s3. Sagar Subhadra, Saraswati, vedika, koel. I want to see how the choice come to koel after tomorrow episode. Sagar ya Mayuri. What will be her choice. Manipulation ya truth. Koel is the power of vyuha, while Yamini is the sakhi of Sagar and his Shakti.
Vedika got her power in Sagar, question is now will Sagar get his Shakti. Game wahan hai. Sagar hi woh madyam hai jisse triveni sangam hoga.
