Quote by River Song

"Spoilers!"

"I'm River Song. Check your records again."

"You can't change history. Well, that's what they always say. But they don't really mean it. You can change it, you just can't acknowledge that you've changed it."

"Hello, sweetie."

"I've seen a lot of things in my time."

"That's how we archaeologists tell time."

"We must learn from history or be doomed to repeat it."

"Every artifact tells a story."
