If they kill off Hinata as well, I'm gonna be pissed!
The fact that the next ep is called 'confession' will probably seal her fate.

On the other hand, I think Pain will have tons of trouble if he fights a Hyuuga 1 on 1. I can't remember a non-filler fight with Hinata, so maybe she will surprise me.
Nagato doesn't really look like he has much of a fight left in him, so that can work for Hinata.

If Naruto has even 1 braincell, he'll use this diversion to gather some nature chackra.
