Re: Michelle and The Doctor (Ten)
"I understand what you meant," Michelle said. "The earth you both came here from, not...Gallifrey." Talking about worlds got even more complicated than usual when you were talking about a 'world'--a universe, really--where there were people on other planets.
"Hmm," she said when he confirmed two functioning hearts. She didn't understand it, but apparently her understanding was not required. An affront that really should be looked into. "Good to know."
"Now that that's established, what's a Time Lord? And how are you and that woman both The Doctor. Use of 'the' implies that there's only one, but there are two of you walking around?"
Michelle looked shocked by an idea. "Do you have to fight to the death? Can there be only one?" she asked with a grin. Was she having him on? A little.
