I don't know, I am big fan of Raj-Pri, and I don't really approve of Hitty, But I feel he's gonna stick in the show longer.
I hate to say this, but I feel Rajbir might go. He's closed down all his options. All the girls know he's completely into Priyanka, and they don't stand a chance. So logically thinking, they would vote to eliminate someone with whom they don't have a chance. Hitty and the others are still a bit flexible. But ya, Priyanka has the power to decide. If she's fair and takes a poll of everyone's choice (and the girls are not considerate enough to let Rajbir stay for Priyanka), then Rajbir has pretty good chances of going.
But again it's so whatever... Hope the best Man n Bride win.
