This is really strange, I watched her come in and out of the bathroom a couple of times. The camera stalled but resumed the first two times, then when she came into the room when the camera quit, you can see her at the door, not doing anything and the camera froze at 21:40:49. Either she has telekinetic powers or there is something weird happening. Perhaps its the fan, I noticed that Bella didn't have the fan on when she showered.
I think its more likely she found out for herself that the player DB was a player and they're finished. She was out for the evening dressed up and was visibly upset when she came in. I think if VV was going to give them the boot they would have talked to them together.
Also, if they were going to be evicted, you would think that Nastya would be somewhat upset also, which she isn't.
I've watched all the archives of the shower cam and as I said, there's only circumstantial evidence and no absolute proof.
Pure speculation on the part of those that have a need to lay the blame on someone.
