Me/Ashildr: You've had an impact on this world. You've made waves.
The Doctor: Sometimes tidal waves.
Me/Ashildr: I'm flattered.

Me/Ashildr

Sam Swift: Who's this, your sidekick? You got your dad as your sidekick?
The Doctor: I'm not his dad, I'm the Doctor.
Sam Swift: Is that the best name you could come up with?
The Doctor: What, says Sam Swift the Quick? Trying a bit too hard, isn't it?

The Doctor: His life force is opening a portal.
Me/Ashildr: To my new life.
The Doctor: Or to Hell.

The Doctor: Why are you still alone? What happened to the second immortality charge I gave you?
Me/Ashildr: No one's good enough.

The Doctor: Ashildr.
Me/Ashildr: That's not my name. I don't even remember that name.
The Doctor: Well, what do you call yourself?
Me/Ashildr: Me.
The Doctor: Yes. You. There's nobody else here.
Me/Ashildr: No. I call myself, Me. All the other names I chose died with whoever knew me, Me is who I am now. No one's mother, daughter, wife. My own companion. Singular. Unattached. Alone.

Ashildr: But they're kind and brave and strong. And I love them.
The Doctor: Good, but that won't save you.

Go. Now. Go find Vikings on other planets. The universe is full of testosterone. Trust me, it's unbearable.

A good death is the best anyone can hope for, unless you happen to be immortal.

The Doctor

Clara: You're always talking about what you can and can't do, but you never tell me the rules.
The Doctor: We're time travelers. We tread softly. It's okay to make ripples, but not tidal waves.

Doctor Who Quotes

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]

Great men are forged in fire. It is the privilege of lesser men to light the flame. Whatever the cost.
