according to new spoiler

 Ishani is impressing me day by day I got so happy ishani will not believe chirag. And throw chirag out she would have done before leap.   So know what will chirag new plan. He know he keeping falling to make ishani trust him again.  And disha will also seen chirag.

This is what I think chirag use disha to make ishani believe him again, as he will tell that ranveer is murder of her father. I m sure disha will chirag she all ready think ranveer destroy her life through rishi.

So then disha will  brainwash ishani against ranveer. Chirag will know she may not believe him (chirag)but she  will believe her sister.

Guys this may or may not happen this only my guess. 

What do guys thinks what will chirag next move.
