The Doctor: What’re you doing?!
Nardole: Fire, oxygen. Basic physics, innit?
The Doctor: Could’ve been basic *death*!

Bill: If there *are* people here, why would they bother writing messages on the surface of the planet?
The Doctor: State visit, patriotic fervor… rogue graffiti artist…

It’s a five thousand-year-old pyramid. There’s one problem with that, one little problem -- wasn’t there yesterday.

Colonel Brabbit

The Doctor: The end of your life is already begun. There is a last place you will ever go, a last door you will ever walk through, a last sight you will ever see. And every step you ever take is moving you closer. The end of the world is a billion, billion tiny moments. And somewhere, unnoticed, in silence or in darkness, it has already begun.
Bill [outside the TARDIS]: ...Are you talking to yourself in there?

The Doctor: How’d you get [the TARDIS] out of my office? The windows aren’t big enough!
UNIT Commander [awkwardly]: Oh… They are now.

Monk: We know you.
The Doctor: Then you’ll know there is a line in the sand, and I’m the man on the other side of it. You wanna keep me that way.

Colonel Brabbit: You don’t look much like guardian angels.
Monk: We have chosen this form to look like you.
Colonel Brabbit: You look like corpses.
Monk: You are corpses to *us*.

The Doctor: You could take this planet in a heartbeat. Why do you need consent?
Monk: We must be wanted. We must be loved. To rule through fear is inefficient.
The Doctor: Of course… fear is temporary, love is… slavery.

Monk: Without our help, planet Earth is doomed.
The Doctor: Yes! Well, it’s been ‘doomed’ before! And guess what happened? Me!

Colonel Brabbit: Listen, isn’t it just worth *considering* doing the deal?
The Doctor: What deal?
Colonel Brabbit: All we have to do is consent.
The Doctor: That’s what the Secretary-General thought, and they burned him!
Colonel Brabbit: He was afraid. I’m not being afraid, I’m being smart.
The Doctor: Yeah. Being smart is not giving away your planet!

I’m not gonna lie to you, this means your insurance premiums are gonna go through the roof. In fact, pretty much everything is gonna go through the roof, because I’m gonna *blow up the lab*!

The Doctor

Hello, I’m the Doctor, saving the world with my eyes shut!

Doctor Who Quotes

That's the trouble with hope. It's hard to resist.

The Doctor

Only in darkness are we revealed. [...] Goodness is not goodness that seeks advantage. Good is good in the final hour, in the deepest pit, without hope, without witness, without reward. Virtue is only virtue in extremis. This is what *he* believes, and this is the reason above all I love him, my husband. My madman in a box. My Doctor.

Nardole [quoting River Song]
