Ishita's detective Instict

Ishita is a very clever lady who thinks practically. But with the current on going track why is Ishita's detective feeling not kicked in yet? Will at any point Ishita be able to correlate between what Ruhi said when she saw the snap of Adi's car and Raman blurting out that she knows only half the truth ? This might make her the jasoos again and save Raman? Or as usual will Raman emerge out as a hero in some manner turning the tables on Shagun after all this drama?
