- Ben Jackson: [Ben picks up the Doctor's ring from the floor] Now look, the Doctor always wore this. So, if you're him it should fit, now shouldn't it?
- [Ben grabs the Doctor's hand, and slips the ring on. However, the ring is far too big for the Doctor's finger]
- Ben Jackson: There... That settles it!
- The Doctor: I'd like to see a butterfly fit into a chrysalis case after it's spreads its wings.
- Polly Wright: Then you did change!
- The Doctor: Life depends on change, and renewal.
- Ben Jackson: [sarcastically] Oh, so that's it, you've been renewed, have ya?
- The Doctor: [taking Ben's remark seriously] I've been renewed, have I? That's it, I've been renewed! It's part of the TARDIS. Without it I couldn't survive.
- Daleks: Advance and attack. Attack and destroy. Destroy and rejoice.
- Hensell: Now look here - I run this Colony. I'm entitled to know why you have come to Vulcan? What is your brief?
- The Doctor: I am the Examiner.
- Hensell: Why are you here?
- The Doctor: To examine. And I intend to start my examination at once!
- [last lines]
- The Doctor: [Ben and Polly follow the Doctor into the capsule and find the cobwebbed Daleks] Polly, Ben... come in and meet the Daleks.
- Ben Jackson: What?
- The Doctor: The Daleks.
- Polly Wright: You could have opened this before!
- The Doctor: These two pieces of metal are identical. The Doctor got one of them from the Daleks himself.
- Ben Jackson: Why do you keep saying the Doctor if you mean you?
- The Doctor: I knew I should find them here, I knew it.
- Ben Jackson: Ah, they look harmless, not very lively.
- Polly Wright: What do you think? Two hundred years in a swamp and you wouldn't look very lively either. Nothing could live through that could it?
- Ben Jackson: Live?
- The Doctor: Nothing human. No.
- Polly Wright: Doctor, look!
- Ben Jackson: What's the matter?
- The Doctor: [the Doctor has noticed something strange about the floor. He bends down to examine it] There were three Daleks in here! What's happened to the other one?
- [Behind the Doctor, a gruesome claw-like appendage crawls from out of the shadows. Paralysed with fear, Ben chokes]
- Ben Jackson: Doctor!
- [Polly gasps, as the Doctor turns to confront the horror]
- [first lines]
- Polly Wright: [inside the TARDIS, the Doctor is regenerating. Ben and Polly watch in amazement as the frail old man changes into a younger figure. Ben and Polly discuss the "new" Doctor lying on the floor of the TARDIS] His face, his hair. Look at it!
- Ben Jackson: He's breathing, and the TARDIS seems to be normal.
- Polly Wright: Ben, what are we going to do? We can't just leave the Doctor there.
- Ben Jackson: What, him? The Doctor?
- Polly Wright: Well that's who came through the doors - there was no one else outside. Ben, do you remember what he said in the tracking room? Something about "This old body of mine is wearing a bit thin".
- Ben Jackson: So he gets himself a new one?
- Polly Wright: Well, yes.
- Ben Jackson: Do me a favor!
- Polly Wright: Then whatever happened, happened in here.
- Ben Jackson: But it's impossible!
- Polly Wright: Not so long ago we'd have been saying that about a lot of things.
- The Doctor: [the Doctor awakens and mutters to himself] Slower. Slower. Concentrate on one thing. One thing. It's over. Hmm, hmm, hmm. It's over.
- Ben Jackson: Doctor?
- The Doctor: [the Doctor turns and stumbles over the console. Mutters to himself] The muscles are still a bit tight.
- Ben Jackson: What are we gonna do?
- Polly Wright: It is the Doctor. I know it is... - I think.
- Ben Jackson: It's not only his face that's changed. - He doesn't even act like him. Come on, it's time we sorted this out.
- Ben Jackson: [Ben walks over to confront the stranger] Now look here!
- The Doctor: [thrusts a mirror into Ben's hands] Hold that. Tilt it.
- [the doctor sees his previous incarnation in a mirror]
- Ben Jackson: [referring to the mirror] Have you done with this?
- The Doctor: Put it down. Put it down.
- Ben Jackson: Now, what's the game?
- The Doctor: [ignoring Ben, the Doctor pulls out an ornamental dagger from one of his pockets. He examines the object thoughtfully] Ah! The Crusades, from Saladin. The Doctor was a great collector wasn't he!
- Polly Wright: But you're the Doctor!
- The Doctor: Oh, I don't look like him.
- Ben Jackson: Who are we?
- The Doctor: Don't you know?
- [places the dagger back in his pocket, and then brings out a dull-looking piece of metal. A look of fear appears on his face]
- The Doctor: Extermination.
- [Ben and Polly look at each in mutual puzzlement. The Doctor replaces the metal back in his pocket, and gives a cry of joy when he discovers a magnifying glass. Peering through the magnifying glass, the Doctor studies his hands]
- The Doctor: Ah... Oh, very good. Nails need growing.
- The Doctor: Come here!
- [softly]
- The Doctor: Come here. The Doctor kept a diary, didn't he?
- Polly Wright: Yes.
- The Doctor: I thought so. I wonder where. I wonder where.
- Polly Wright: He's a very different Doctor, Ben.
- Ben Jackson: Yeah, maybe. Just where do we stand, though?
- Polly Wright: Doctor? Doctor, what's going to happen to us?
- The Doctor: I think... I think we must have landed for sometime. I think it's time we went for a stroll.
- Polly Wright: But you don't know where we've landed!
- Ben Jackson: No! You haven't checked the oxygen or the temperature or anything!
- The Doctor: [not looking up from the 500 Year Old Diary] Oxygen density 172, radiation nil, temperature 86, strong suggestion of mercury deposits. Satisfied, Ben? Now, are you two coming or are you not?
- Polly Wright: He does know us! He said "Ben", didn't you hear him?
- Ben Jackson: Yeah, I heard. But he might just have been copying you though, mightn't he?
- The Doctor: [about the Dalek metal] A hundred years you say this has been buried?
- Lesterson: Oh, at least. Now, there must be something in the inner compartment. We shall be able to find out where it came from originally.
- The Doctor: It didn't come from this planet - Vulcan.
- Lesterson: Oh no, no, no. The metal is quite alien.
- The Doctor: Alien, yes. Very alien. Goodnight.
- [the Doctor rapidly and abruptly leaves the lab]
- Ben Jackson: What's he up to now?
- Polly Wright: Ben, we're not going to let him out of our sight.
