I feel Dipika always wins in such tasks becoz:
1. Such tasks basically require pointing out others' faults and mistakes, which Dipika is quite adept at. As it is, she regularly keeps complaining about most housemates; the only difference here is just saying that out aloud in front of others.
The only person she finds perfect is Sree!
2. Dipika holds grudges very well. She never forgives or forgets. She remembers exactly when someone did something to irk her and since initially she didn't confront others directly, she got a chance to do so in these tasks.
3. Dipika is excellent at defending a friend's mistakes and shifting blame onto someone else. So, in these tasks, she expertly maneuvered many ilzaam (isn't is actually Sree who is most over-confident or most agressive etc.?) onto someone else.
4. Dipika uses these tasks as an excellent opportunity to get back at all the housemates who might have done/spoken anything against her/Sree.
I feel a person is strong if he/she can provide mental strength to others along with self. How is being good at arguments and being adept at pulling down others a sign of strength??
