So with that in mind, they probably are hoping that when Suhani comes to know the truth that Yuvraj loved Soumya and now it's vice versa, she will begin to dislike Yuvraj and leave them. Then have Soumya do things to impress Yuvraj.
Soumya lied to Dadi that her dinner date with Yuvraj went great. So I don't know if she will lie to Dadi about Yuvraj answer. The way the scene plays in my head is that Soumya gets Yuvraj confession that he loves Suhani. Soumya refuses to believe it and as proof asks him to tell Suhani the truth. Since Soumya didn't care Yuvraj during the engagement, she hid the truth from Yuvraj about Krishna. So if he loves and cares for Suhani then he should tell her the truth and until then she will stay in the house. Soumya probably tells Dadi a lie that she feel Yuvraj is denying his love because Suhani is in his life and until she leaves he won't say he loves her. Hence they hatch a plan to tell Suhani. If it fails and Yuvraj comes to know of they plans, Soumya could always act innocent and say it was all Dadi's fault, she manipulated her since she know that Soumya loves Yuvraj.
Just a thought. I don't want to blame CV for not thinking up the scene completely because that episode hasn't been shown on TV yet.
