“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives.”

“People assume that time is a strict progression of cause to effect, but *actually* from a non-linear, non-subjective viewpoint - it's more like a big ball of wibbly wobbly... time-y wimey... stuff.”
― Steven Moffat

“Demons run when a good man goes to war
Night will fall and drown the sun
When a good man goes to war

Friendship dies and true love lies
Night will fall and the dark will rise
When a good man goes to war

Demons run, but count the cost
The battle's won, but the child is lost”
― Steven Moffat

“She looked at me, like she was drinking in the fact that I was still here. And I realized I was doing the same thing. The world was collapsing, and the only thing that really mattered to me was that she was alive.”
― Rick Riordan, The Last Olympian
