I am also in dilemma, though I am not watching show and I get idea what is going on from forum. I found few things. What I felt from few scenes that, Ishita sometimes felt like Ishita, Shagun, Ishgun and sometimes unusual which doesn't match any of these. So, is there any kind of continuous swapping. I mean sometimes it's original Ishita, sometimes its complete Shagun, sometimes Ishgun and sometimes all together different. So, is it some fake Ishita.
CVs have really gone crazy, but the way they are going they can't justify Ishita's action completely. It can be only if we missed some loop holes or there are some more folds to it. Like few more guys as part of plan, or the person itself is fake.
I don't know what I am writing exactly. I know I am finding myself really foolish and stupid writing all this.
Now it's revealed that its a plan then the act should be made justifiable too, with their illogical logic. To some extent the plan would have been good but they are really going overboard. Sorry, and no offence guys.
