Even in the task, Jasleen accepted her weak points and did not argue to claim herself as superior to others, she knew Dipika is a stronger contestant than her at the moment because she is being seen more and Jasleen has not been targeted that much.Jasleen did not argue because she knew how she has to improve her game and be more visible in the house.
It is all because of that Anup who poisoned Jasleen's mind against Dipika because before him entering the house, Jasleen had no issues with Dipika. Jasleen also praised Dipika that, she has a lot of involvement in the house, she is atleast honest enough to accept that her competitor is doing better than her instead of trying to prove how she is better than Dipika.
