Flatline
Clara:Why can't the TARDIS just translate?
The Doctor:Because their idea of language is just as bizarre as their idea of space. Frankly, the TARDIS is confused.
Fenton:What makes this colleague of yours even think those monsters want to talk?
The Doctor:I know of a race made of sentient gas who throw fireballs as a friendly wave. I know of another race with 64 stomachs who talk by disembowelling... My point being: in a universe as immense and bizarre as this one, you cannot be too quick to judge.
In the forest of the night
The Doctor:I'm afraid clever isn't much use against trees. They don't listen to reason. You can't lie to them. You can't plead with them. They have no moving parts, no circuits, no Wi-Fi. You wave your sonic screwdriver at them all you like and they just keep growing. This is a natural event.
Danny:How can it be natural for a tree to grow in a night?
The Doctor:Exactly what they said about the Ice Age. How can whole glaciers just pop up out of nowhere? They just did. That's how this planet grows - a series of catastrophes. The Ice Age is over. Welcome to the Tree Age.
Dark waters
The Doctor:This is it, Clara, one of those moments.
Clara:What moments?
The Doctor:The darkest day, the blackest hour. Chin up, shoulders back - let's see what we're made of, you and I.
