Bonnie: It's empty, isn't it? Both boxes. There's nothing in them, just buttons.
The Doctor: Of course, and you know how you know that? Because you've started to think like me.

Clara: You must have thought I was dead for a while?
The Doctor: Yeah.
Clara: How was that?
The Doctor: Longest month of my life.
Clara: It could only have been 5 minutes.
The Doctor: I'll be the judge of time.

I'm sorry, Clara is dead. Kate Stewart is dead. The UNIT troops are all dead. Truth or consequences.


Clara: Oh my God, that's me.
Jac: I think we should wait.
Clara: Look, they're here. They're growing duplicates of us. We have to destroy them. I've seen this happen before. It happened to that little boy. They took his parents and then they took him.
Jac: But I don't see how these are duplicates. That's not how Zygons work. They don't grow duplicates. They kidnap the originals so, these... These are the humans!

The Doctor: Which one are you? Human or Zygon?
Osgood: I don't answer that question.
The Doctor: Why not?
Osgood: Because there is no question to answer. I don't accept it.

Kate: You left us with an impossible situation, Doctor.
The Doctor: Yes I know, it’s called peace.

Any living thing in this world, including my family and friends could turn into a Zygon and kill me. Any second now. It's not paranoia when it's real.


Clara: So Osgood's been kidnapped, right? I thought Osgood was dead.
Kate: There have always been two of her, ever since the cease fire. We never knew which one was real.
The Doctor: Both of them.
Kate: Okay, which one was Zygon.
The Doctor: Both of them. They would have maintained a live link. They were both Zygon and human at the same time.

Osgood 1: The Zygons are a peaceful race.
Osgood 2: Their shape changing abilities should not be considered a weapon.
Osgood 1: It's a survival mechanism.
Osgood 2: They embed themselves in other cultures and live out their lives in their new bodies, in peace and harmony. Mainly.

Enemies are never a problem. It’s your friends you have to watch out for.


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

You didn't save my life, Doctor. You trapped me inside it.


Doctor Who Quotes

You’ll find that it’s a very small universe when I’m angry with you.

The Doctor

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