The Doctor: It's only 2018. I thought we'd leaped into the Wooly Rebellion.
Yaz: Sorry, what?
The Doctor: The Wooly Rebellion. In 193 years, there's a total renegotiation of the sheep-human relationship. Utter bloodbath.

Ryan: Maybe we shouldn't be in here.
Yaz: There's a child in this house.
Graham: Or some maniac who collects kids' shoes.

Ryan: Woah. Why are we not in the mirror?
Graham: I don't know.
Ryan: We'd know if we were vampires, right?

Graham: Hey, Doc, do you think it's safe?
The Doctor: I doubt it. It's a jittering dimensional portal in a mirror in a Norwegian bedroom.

Ribbons: Bird is lunch. Maybe codger is tea.
Graham: Who are you calling a codger? It's you who stinks of his own wee.
Ribbons: That's not my wee.
The Doctor: Let him go cause you do not want those words to be your last ones.

The Doctor: What did he look like? This man.
Ribbons: No horns. One mouth. So ugly. Like you. But such nice big boots.

The Doctor: Solitract! It's a theory, a myth, a bedtime story my Gran used to tell me.
Yaz: You had a grandmother?
The Doctor: I had seven but Granny Five, my favorite, used to tell me about the Solitract.

She's not your wife! She's furniture with a pulse.

The Doctor

This woman is clearly an alien force, collapsing two realities and impersonating your dead wife. Time to move on, mate!

The Doctor

The Doctor: The Solitract is a frog? Who talks like Grace?
Solitract Frog: My own form is endless but this frog is a form that delights me as it once delighted Grace.
The Doctor: There's me thinking the day had no more surprises left.

You are the maddest, most beautiful thing I've ever experienced and I haven't even scratched the surface. I wish I could stay. But if either of us are going to survive, you're going to have to let me go and keep on being brilliant by yourself.

The Doctor

Andinio: It's time. You ready, Delph?
Delph: I don't think I am.
Andinio: Seventeen years is enough. This is what I've trained you for.
Delph: You call it training. I call it building doubt. Every lesson that you've given me, I feel like I've understood less, not more.
Andinio: Which is the point. The more we learn, the less we realize we know. This is our faith. This is our existence. The Creator would contend the world is not to be understood, only experienced.

Doctor Who Quotes

There's a horror movie named Alien? That's really offensive. No wonder everybody keeps invading you.

The Doctor

The Doctor: It's a risk.
Graham: Oh, like none of our other trips have ever been risky.
The Doctor: I have apologized for the Death Eye Turtle Army! Profusely.
