Caitlyn smiles and rolls her eyes. The Doctor was right, this wouldn't really kill Jack, not that much could really kill the immortal for good, besides from perhaps real old age, but she still was inexplicably frightened that this would be the last chance for a while to be like this. And she knew to count on her instincts enough to know that, that was exactly what was going to happen. "I'll make sure he gets some fluids and whatnot."

Rose wanted to be as prepared for whatever was going to happen with the Master, the guy who the Doctor was worried for a look of curiosity on her face. "Did you choose these titles where you grew up?" She asks knowing that it was next to impossible to talk to the Time Lord about his home, and where he came from, she was just generally curious about it. She was also curious if the Doctor had a true name. But then scoffs silently. He must have. It's just buried and kept secret, she guessed.
