EDIT: TALKING ABOUT THE GOLD MINING TASK HERE.
It was very simple. Yes, it would have been very blatant and unfair. But it could have been done. Maybe he should have stuck to his principles and tried to get her in.
But I do agree with the flip side
1. Afsana is not at all a good player
2. She is not one to help herself. She was completely dependant upon Umar/Karan to get in. She never could have gotten in on her own.
How much can you help a contestant like this?
