“The Satan Pit” quotes from Doctor Who

This is the darkness. This is my domain. You little things that live in the light, clinging to your feeble suns, which die in the end. Only the darkness remains.

If you are "the Beast", then answer me this - which one? Hmm? 'Cause the the universe has been busy since you've been gone. There's more religions than there are planets in the sky! The Arkiphets, Quoldonity, Christianity, Pash Pash, New Judaism, San Klah, Church of the Tin Vagabond - which Devil are you?

All of them.

What, then you're the truth behind the myth?

This one knows me, as I know him. The killer of his own kind.

You want voices in the dark? Then listen to mine! That thing is playing on very basic fears. Darkness, childhood, nightmares, all that stuff.

But that's how the devil works!

Or a good psychologist.

You get representations of the horned beast right across the Universe. In the myths and legends of a million worlds: Earth, Draconia, Vel Consadine, Dæmos, the Kaled god of war. It's the same image, over and over again. Maybe that idea came from somewhere, bleeding through, a thought at the back of every sentient mind.

Emanating from here?

Could be.

But if this is the original, does that make it real? Does that make it the actual Devil?

Well, if that's what you want to believe. Maybe that's what the Devil is in the end: an idea.

[about Rose] I've seen fake gods and bad gods and demigods and would-be gods; out of all that, out of that whole pantheon, if I believe in one thing... just one thing... I believe in her.

[possessed by the Beast for the last time] I AM THE RAGE AND THE BILE AND THE FEROCITY! I AM THE PRINCE AND THE FOOL AND THE AGONY! I AM THE SIN AND THE FEAR AND THE DARKNESS! [opens his mouth and breathes fire]

What is he?! What the HELL is he?!

I SHALL NEVER DIE! THE THOUGHT OF ME IS FOREVER; IN THE BLEEDING HEARTS OF MEN, IN THEIR VANITY AND OBSESSION AND LUST! NOTHING SHALL EVER DESTROY ME! NOTHING!

[aiming a yellow-stripped Boltgun] Go to Hell. [Rose fires at the ship viewscreen, causing it to suck Toby (and the Beast) out of the ship and into the black hole]

But Doctor, what did you find down there? That creature, what was it?

I don't know. Never did decipher that writing. But that's good! Day I know everything? Might as well stop.

What do you think it was, really?

I think... we beat it. That's good enough for me.
