He is stuck to Nikki because she is clearly the strongest of all contestants right now. Pavitra had a chance at that, but Rahul bhai is kind of glued to her.
In today’s episode, from the snippets that I watched, Rahul passed some classless comment about Gajra at Nikki. Jaan stepped in again and unnecessarily tried to butt in. If Nikki wanted the items, that was her right. Rahul also had the right to give her the reality check.
Jaan, on the other hand, tried too hard to be in Nikki’s good books. Nowadays, his bromance with Eijaz is making the rounds.
