She could choose anyone- Shardul, Naina, Abhinav etc. But she chose Kavita. The gal who rescued Ejaj from Red zone. This was her own sochi samjhi plan. If Ejaj didn't choose her she could blame Ejaj as ehsaan farmosh. What choice Ejaja had? In both way he would be the ungrateful man, a deal breaker.
So this was Niki's plan.
Niki says she respects frndship. Well she just broke one. If I see this as a player's perspective I'd say brilliant game plan. Sanp bhi mara but uff tak nehi kiya. No one identified the puppet master.
Somehow I think now Ejaj is understanding this that he and Kavita became the puppets of Niki. That is why he made Niki his bai. If Niki denied him he would send her to Red zone again. But couldn't . She once again made his plan a failure by obeying his order which is absolutely not her nature. Why? She is playing a victim here. So that to morrow when the whole house go against Ejaj she could tell she was a victim too. Next nominate Ejaj and somehow kick him out or to red zone.
Well played Niki! 👍🏼
