River was watching Rose intently as she froze. Obviously, what she said got to the girl and quite frankly, she was glad it did. Rose was being a child in River's eyes.

Did she know Rose's fate? Maybe, maybe not. It was hard to tell what she might know and what she didn't considering how much she learned traveling with him and even from the Tardis herself. Then again, Spoilers.

So, she let the girl work it out and just waited until she was done. Though, before River could say anything, the girl became a wolf and bolted. Well, that was a new one on her to say the very least. It also seemed to cement a few things Rose said about this place to River and that alone made her even more curious to see the effects this place had on The Doctor.

River also had a feeling, things were going to be a lot more complicated than usual when they finally met up again.
