I can give Somi the benefit of doubt that, he might have not seen that, Megha;'s bowl had some drops left because Somi was reacting instantly and she was not bale to have control over her temper.
However, Dipika did disqualify Megha first, but when she saw that, Megha had some left, the she changed her decision.Romil's reason was also right that, Somi did not cross the boundary and it can still be counted for Megha being disqualified, but Megha was honest when she said that, her bowl was not completely empty.
Dipika never helped Karanvir in the task and was pretty fair because she disqualified him twice but he still had some drops left,so if she is giving Megha that much convenience, then why not Karanvir. Your bowl has to be empty , but when it is not empty, you are still part of the game.
Dipika made deciions that were fair and when she had proper evidence form Karanvir that, he has drops left, only then she allowed him to be back in the task.
Sreesanth, Surbhi, Deepak, Romil,and Somi were wrong in putting the blame on her. they could not get any reason to make her look negative, thus made false allegations on her.
