Looking at how things are going now in Saarrthi, i have a feeling that Mamaji and Mansen might be the ones to expose Shefali.
Arjun, Bhoomi and Yuv trust Shefali. The way Shefali is playing things, she is putting all the blame on Yuv. Arjun and Bhoomi do not trust Yuv and the way things are going there is bound to be a misunderstanding (maybe its a mild word) btw Yuv and Arjun.
Mamaji and Mansen do not trust Shefali. Mansen had said in a previous episode that Shefali is trying to create distances btw Yuv and Arjun and he will not let that happen, and they keep showing the mistrust M and M have for Shefali.
I have a feeling that maybe Mamaji and Mansen will be the ones to expose her.
