It could also be Prateek , when Shagun asked today about how Ishita is, how he came to know that network is not there? Also, if Sarika was the one who attacked Ruhi, then ACP must be involved also, but my guess is Romi as Romi and Sarika are definitely planning this from long as they see their personal benefit after Raman's death. Also they both must be planned their fight so that it looks real.
2. I feel Manoj is back as once PriyaRay also said that Manoj is going to be the crucial man in all this. Why i feel that jungle murder day somehow, When Ishu saw someone, it could well be Manoj also, and the place where Prateek took hold ,and dropped him , i got a feeling that the same place Pathak was found . maybe some secrets. Dont know anyone possible. Even Mihika and vandu are under cloud of suspect.
So many doubts , can only get clear when original one is found.
