I am pretty sure, you wouldn't have noticed this thing.
The mastermind of this season were two silent players:
1) Ankit
This guy signed this show along with her co-star. Then he ditched her when he was being bashed everytime. It's kind of evidence that these two were supposed to be enter as couple. But Ankit changed the equation as friends so that it not only blamed on Priyanka who is already obsessed and he would easily play victim. He stopped taking stands for her, he knows everything that Pri was wrong still he never correct her because he wants her to be bashed. It's not love but called smartass.
2) Tina Dutta
Dolly - i think it's diljeet ...
Tina Dutta already knew sha, and she even know about his dark past. The reason that both got comfortable and cozy had me in doubts... Tina started this relationship drama and when Sumbul matters came out.. she started realising that she has messed up the game. She wanted Sha as toy because of him, her image is being turnished so she will do the same with him by webbing a love game. Secondly, Tina Dutta knew that contestants here are strong and they are playing really with smartness. So, one by one she started enjoying the companies to know the secrets and sha being stupid couldn't understand that she doesn't care for him. She was using him just for her game and revenge.
