DOCTOR: Oh, the blossomiest blossom. That's the only sad thing. I want to know what happens next. Right, then. Doctor Whoever-I'm-about-to-be. Tag, you're it.

DOCTOR: Because something seems impossible. We try, it doesn't work, we try again. We learn, we improve, we fail again, but better, we make friends, we learn to trust, we help each other. We get it wrong again. We improve together, then ultimately succeed. Because this is what being alive is. And it's better than the alternative. So come on, you brilliant humans. We go again and we win. Deal?

DOCTOR: Two hearts. One happy, one sad.

DOCTOR: Humans. I think you forget how powerful you are. Lives change worlds. People can save planets, or wreck them. That's the choice. Be the best of humanity.

DOCTOR: None of us know for sure what's out there. That's why we keep looking. Keep your faith. Travel hopefully. The universe'll surprise you... constantly.

DOCTOR: I know there aren’t many certainties in any of our lives, but Umbreen, Prem, what I see you in you is the certainty you have in each other. Something I believe in my faith. Love, in all its forms, is the most powerful weapon we have, because love is a form of hope and, like hope, love abides in the face of everything. You both found love with each other. You believed in it, you fought for it, and you waited for it. And now, you’re committing to it. Which makes you, right now, the two strongest people on this planet.

DOCTOR: I'm the Doctor.

MABLI: A doctor of medicine?

DOCTOR: Well, medicine, science, engineering, candyfloss, LEGO, philosophy, music, problems, people, hope. Mostly hope.

DOCTOR: We’re all capable of the most incredible change. We can evolve while still staying true to who we are. We can honour who we’ve been and choose who we want to be next. Now’s your chance. How about it?

DOCTOR: We all change, when you think about it. We're all different people all through our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people that you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me.

TENTH DOCTOR: Oooh, lovely.

ELEVENTH DOCTOR: Oooh, lovely.

ELEVENTH DOCTOR: It's a timey-wimey thing.

WAR DOCTOR: Timey what? Timey-wimey?

TENTH DOCTOR: I've no idea where he picks that stuff up.

TENTH DOCTOR: Trenzalore. We need a new destination, because I don't want to go.

ELEVENTH DOCTOR: He always says that.

ELEVENTH DOCTOR: I never forget a face.

CURATOR: I know you don't. And in years to come, you might find yourself revisiting a few. But just the old favourites, eh?
