Prediction: Ishitha + Shagun to Trap

I am more or less sure that, both of them are together. They would like to trap both Ashok and Sarika. For whatever could be the reasons. Only these two seem to be aware of supposedly possessed Ishitha's 'wrong' actions.

I think Shagun would have met Ashok before the supposed death and must have talked nicely and convincing way. Then the two ladies would have planned all this.
