Rose paused and smiled at the new man. Something about him tickled the back of her brain. What was it? Not the Doctor's past faces, and something about the goatee in particular seemed to want to conjure a picture. What was it? Something about sexy and sunglasses??? The Doctor's future?? It wasn't his past, she was sure of that. After her fumble with 8 at first, she made sure to memorize his past faces so she didn't mess up like that again. She hesitated, still smiling. Should she put the ring on her chain or not? The Doctor's oldest version was so happy about it, and even his past seemed nonchalant, but if it was a future version of the Doctor...

Well, so what if it was?!

"Hello," Rose beamed, clearly testing the waters, and gently, casually-ish waving the hand with an unmistakable blue star diamond TARDIS ring on it, "Welcome to Nautilus, yeah?"
