The new captaincy task has created trust issues between friends. It started with Vikas reading out the rules of the captaincy task, where Aly and Sonali were the moderators and scientist who were supposed to check pills on rats i.e housemates.
The green pill will save rats and the red will kill them. Aly and Sonali first called Nikki and as she chooses the red pill as Aly asked her to do so, she felt betrayed and fought with Jasmin and Aly for playing wrong with her.
