Definitely the Khuranas nor the Sareens nor Soni could be Cherry's helper. Soni loved Veer and Cherry was after her, obviously. Mr. K, Durga, Jeet, Jyoti, and Lovely are Veer's blood. Shabd and Kamya are Veer's blood too - cousins, and Mahi adored Veer as her jeeju. The tayiji-tayaji would not do it either. So the left out ones are Parmeet, Moni, Gauri, Harry, and now Angad too being added to the list! BTW, where was Angad all these years -was he in Canada as well?!
Out of the above, I dont believe Harry has any hand, and Moni is too fragile to get in through the window and jump out of the window of Jeet's room. Gauri too doesnt look bold enough to do that, plus she has never been to the Khuranas and so she wont be familiar with the layout of the rooms there. But I remember that it was mentioned once that the tape was swapped inside or on the way to the court room itself!? If that's the case, only Moni and Parmeet were present there apart from the family...
So all points to Moni and Parmeet, unless they are going to bring a hidden character! Parmeet was referring to Jyoti when he said someone doesnt want him to be there, and that was very clear. Also they talked about going out for dinner that night, and so Cherry might have kidnapped Jyoti and appeared before Parmeet in the restaurant, who knows! I feel Cherry is on a mission to destroy the Khuranas and take control of their wealth, though I dont know why if she is richer than them??
