Doctor Who

"You were my best friend. You still are."

"The future isn't written yet. We can still change it."

"I've learned that love makes you do extraordinary things."

"There are things you can't fight just with strength."

"I'm going to find you, no matter what it takes."

"Sometimes the bravest thing you can do is ask for help."

"You taught me how to be brave."

"I've got to believe there's something better out there."

"Every moment with you is precious."

"That's what makes us human - we don't give up."

"You're not alone in this. You've never been alone."

"The Doctor showed me that the universe is so much bigger than London, bigger than Earth. How can I ever go back to ordinary after that?"

"I want to see it all - the galaxies, the nebulas, everything."

"But you can save them. You can save everyone."

"I'm scared. I'm really, really scared."

"You're gonna have to start trusting me."

"How do you do it? How do you keep on fighting?"

"Nothing's impossible. I've learned that from him."

"There's a whole universe out there, just waiting."

"I spent so long looking for you, and in the end... you can run, but you can't escape it."

"The way I see it, every life is a pile of good things and bad things. The good things don't always soften the bad things, but vice versa, the bad things don't always spoil the good things or make them unimportant."

"I'm not leaving you. Not ever."

"Stupid aliens chasing me. This is so typical."

"I've seen so much, lost so much. But I wouldn't change a thing."

"You make it all worthwhile."

"I don't want to go."

"Just... you and me and a box in the sky."

"I'm not clever or brave or strong. I'm just an ordinary girl from London, but I've seen things that will change the way you see the universe forever."

"The strongest walls are built from compassion, not stone."

"Creativity is the highest form of intelligence."
