“Love has never been noted for its rationality.”

RUBY: We made it. The human race, we survived. We went to the stars. And ten minutes ago, Doctor, just ten minutes ago, you said genocide. Your people are gone.

DOCTOR: Yeah.

RUBY: How do you keep going?

DOCTOR: For days like this, Ruby Sunday. I don't have a people. I don't have a home. But I don't have a job, either. I don't have a boss, or taxes or rent or bills to pay. I don't have a purpose or a cause, or a mission, but I have... ..freedom. And so I keep moving on, to see the next thing, and the next, and the next. And sometimes... it looks even better through your eyes.

DOCTOR: Oh, that's good. DuBarryDuPlessy is a starwide organisation. It means they can take in lots of refugees.

RUBY: Oh. Well, can't we call them for help?

JOCELYN: They don't go and fetch refugees. That's the fate of every refugee in the universe. You physically have to turn up on someone else's shore. And we can't move.

DOCTOR: The Time Lords were murdered. The genocide rolled across Time and Space, like a great big cellular explosion. Maybe it killed her too.

RUBY: Doctor, God...

RUBY: You're scaring me now.

DOCTOR: That thing must be part of the Pantheon. Oh, Ruby, there are vast powers beyond the universe. I told you, when we first met. I said, I said the Toymaker... And defeating him took everything. It ripped me in half.

RUBY: But you survived.

DOCTOR: It literally... it tore my soul in half. I can't survive that again. The Toymaker said... he said, he warned me, he said, "My legions are coming. My legions are coming." He said, "My legions are coming."

DOCTOR: We're all dead eventually. There's hardly any time that we're not dead. Which is a good thing, too. We've got to keep the pace up, otherwise nothing would get done. Dying defines us. Snow isn't snow until it falls.

RUBY: Snow...?

DOCTOR: Yeah, snow. We all melt away in the end, but something stays. Maybe the best part.

“A sad old man once told me, what survives of us is love.”

DOCTOR: Oh, yes! We are in Wales. Spectacular!

RUBY: How can you tell?

DOCTOR: Oh... That smell. That green. That coastline, Ruby. Oh, the rocks and the water, it never ends. The war between the land and the sea.

“I can't think of a synonym for keeping your distance. I suppose, to coin a new word, in Latin, it would be semper distans. Always distant. She's semper distans to you.”

“73 yards. I have measured it 100 times. I've measured it a thousand times. It's 73 yards.”
