“By the way," said Tegan, suddenly very self-conscious. "Thank you." "What?" "You were prepared to give up everything for us." The Doctor just smiled and stood up. "Oh, come on!”
“Oh, come on. Is that all you got?”
“Sometimes walls go up between friends and you can’t see the other side. And sometimes they come down. That’s just the way walls are, and they’re everywhere.”
“What's the nature of your emergency?'oh, shit! Just come! There are dead people out here!”
“There’s no remaking reality... Just take it as it comes. Hold your ground and take it as it comes. There’s no other way.”
