Rose snapped to attention when he talked about lives and wondered just which ones she knew and how many he had gone through and how many more he had on the edge of panicking. She may not remember much from the time she had opened the heart of the TARDIS to save his are, but she knew that he had regenerated by taking the entirety of the time vortex and had wondered if it had been her fault. She smiles at him. He was as easily excitable as the second him she knew and that was adorable. She wished she could help in some way. And then she paused for a moment thinking as the lives had solidified in her head. "So the Master is another Time Lord?" She asked. She wasn't as sure she could keep another of his race out of her head, as she hadn't even known about this Master bloke.
