Of all the adventures River had shared with his future-self, she could honestly say that this had to be the strangest situation they'd gotten themselves into so far, and that was saying something!

As far as she could tell, the Doctor was inside of her.

Let's repeat that, shall we? The Doctor. Is. Inside of her.

It should have sounded sexy, but somehow it felt more like a complete invasion of her privacy. There was simply no way to tell if he had access to her mind and memories, so she tried to put up a tentative psychic and mental shield. Just enough to keep him from being nosy. They had more important things to worry about right now and she knew that would keep him busy.

How is this even possible? Did you touch something you shouldn't have in your study?

Even River didn't know half the things he kept in his study for safe storage, but usually when something went wrong inside the TARDIS, that was the thing to blame. Someone had touched something they shouldn't have. Or aliens were involved.

It's like I can feel you there and you're obviously capable of controlling parts of my body.

His other hand is still buried in her curls.
