MICKEY: So what's the deal with the tin dog?

SARAH: The Doctor likes travelling with an entourage. Sometimes they're humans, sometimes they're aliens, and sometimes they're tin dogs. What about you? Where do you fit in the picture?

MICKEY: Me? I'm their Man in Havana. I'm the technical support. I'm. Oh, my God. I'm the tin dog.

FINCH: You act like such a radical, and yet all you want to do is preserve the old order? Think of the changes that could be made if this power was used for good.

DOCTOR: What, by someone like you?

FINCH: No, someone like you. The Paradigm gives us power, but you could give us wisdom. Become a God at my side. Imagine what you could do. Think of the civilisations you could save. Perganon, Assinta. Your own people, Doctor, standing tall. The Time Lords reborn.

SARAH: Doctor, don't listen to him.

FINCH: And you could be with him throughout eternity. Young, fresh, never wither, never age, never die. Their lives are so fleeting. So many goodbyes. How lonely you must be, Doctor. Join us.

DOCTOR: I could save everyone.

FINCH: Yes.

DOCTOR: I could stop the war.

SARAH: No. The universe has to move forward. Pain and loss, they define us as much as happiness or love. Whether it's a world, or a relationship, everything has its time. And everything ends.

(The Doctor throws a chair at the big screen, smashing it.)
