I have not seen the last 3 episodes. I have however read about Rubina and jasmine fall out. I genuinely adored their bond but I think this is a good opportunity for Rubina to make new friends and alliance.
so what if Rubina and Nikki became friends? I know it sounds bizarre but I think it will be interesting and add some spice to the dynamics in the house.
Nikki has always empathized loyalty and Rubina has been loyal and understanding towards jasmine even after that whole Rahul incident and the nomination task. Nikki has shown to be nice from time to time. Rubina is currently in an emotional state and needs a friend as well as a wake-up call to the initial fighting spirit she had in the first 2 weeks. I think they can be great allies to each other.
this is just my opinion, no hate, please :)
