How do you think JW should resolve the 'black magic' issue?
Personally I would take a vote of all the family members who think Bani entering and living in the house would bring bad luck to them. At this point in time Pia, Saahil, Jigs and amybe Rano would confirm it. He should then agree with their POV and give them the keys to the outhouse and tell them they should move there as the bad luck will then not affect them. They should be left to fend for themselves in the areas of cooking and cleaning as nothing from the house should come in contact with them directly or indirectly. Why can't they show us fun scenarios like these?
