Bill: How is blowing everyone up saving the world?!
CERN Scientist: Because… this isn’t the world!

Okay, Bill. Miss Potts. [removes his glasses] I’m the only person you’ve ever met or will ever meet who is officially licensed to kick the Doctor’s arse. I will happily do the same to you in the event that you do not align yourself with any instructions that I have issued which I personally judge to be in the best interest of your safety and survival. [puts his glasses back on] Okay, Bill?

Nardole

Bill: Are you trying to get rid of us?
The Doctor: Why?
Nardole: ‘Cause you’re sending us into the dark after a man with a gun.
The Doctor: Ah! Well, I thought of that.
Nardole: Thank you.
The Doctor: Nardole, you make sure you walk in front of Bill.
Nardole: Oh, right.

Particle physicists and priests. What could scare them both?

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]

When I’m on a date, when a rare and special thing happens in my real life, do not, *do not*, under *any* circumstances, put the pope in my bedroom!

Bill

Penny: That was the pope! Bill, that was the *pope*!
Bill [resigned]: Yeah… I am about to have a *truly* awesome word with someone…

Memories are so much worse in the dark.

The Doctor

Bill: Doctor… I think I’m alive!
The Doctor: Yes, you seem to be under that impression.

They’re not your rescuers. They’re your replacements. The endpoint of capitalism. Bottom line. Where human life has no value at all. We’re fighting an algorithm. A spreadsheet. Like every worker everywhere, we’re fighting the suits!

The Doctor

You look like you’re trying to run. Would you like some help with that?

Suit Assistant

Bill: What if you’re wrong?
The Doctor: Well, then we’ll be horribly murdered! So let’s say I’m right!
