Welcome to the Ruddy Doctor Caches, a series of puzzles linked together loosely with a whimsical story following the various regenerations of my favourite Time Lord.
The puzzles are nestled away in passages linking the various Doctor’s regeneration scenes, so you’ll need to skim at least through to find the goods and the occasional clue. You can assume coordinates are N 52° 53.XXX' W 001° XX.XXX' and will need you own pen and tweezers. All were conceived and placed by Doctor RuddRobins + checked and difficulty assessed by Mrs RuddRobins.
The notes at the end are random Docfacts not needed to complete the puzzle. I hope you find it all mildly amusing and it keeps you out of trouble for at least a little while J

The Ruddy Doctor 12: The Meta-crisis Doctor
[Tardis]
(The Tenth Doctor’s spare hand is lying on the floor, twitching (no, really). Golden energy surges out and builds a new body for it, which looks just like the old one.)
DONNA: It's you!
NEW DOCTOR: Oh, yes!
DONNA: You're naked.
NEW DOCTOR: Oh, yes. Ah . . guessing you’d prefer I wasn’t?
DONNA: Oh, yes . . .
(The Doctor finds himself a smart blue (not brown) suit and fixes the (mostly superficial) damage to the console room)
NEW DOCTOR: All repaired. Lovely. Shush. No one knows we're here. Got to keep quiet. Silent running, like on submarines when you can't even drop a spanner. Don't drop a spanner! I like blue. What do you think?
DONNA: You are bonkers.
NEW DOCTOR: Why? What's wrong with blue?
DONNA: Is that what Time Lords do? Lop a bit off, grow another one? You're like worms.
NEW DOCTOR: No, no, no, no, no. I'm unique. Never been another like me. Because all that regeneration energy went into the hand. Look at my hand. I love that hand. But then you touched it. Wham! Shush. Instantaneous biological metacrisis. I grew out of you. Still, could be worse.
DONNA: Oi, watch it, spaceman.
NEW DOCTOR: Oi, watch it, Earth girl. Ooo. I sound like you. I sound all, all sort of rough.
DONNA: Oi!
NEW DOCTOR: Oi!
DONNA: Oi!
NEW DOCTOR: Spanners. Shush. I must have picked up a bit of your voice, that's all. Is it? Did I? No. Oh, you are kidding me. No way. One heart. I've only got one heart. This body has got only one heart.
DONNA: What, like you're human?
NEW DOCTOR: Oh, that's disgusting.
DONNA: Oi!
NEW DOCTOR: Oi!
DONNA: Stop it.
NEW DOCTOR: No, wait. I'm part Time Lord, part human. Well, isn't that wizard? Now, we have a puzzley puzzle to solve, don’t we? Probably a big ball of wibbly-wobbly, timey-wimey stuff or something. Lets have a gander:
CBPMCB – CB – SMWHPT
NEW DOCTOR: Ohhh, that’s meta – that’s very fourth wall aware that is, I mean I know I’m all about the metacrisis and everything but this is PROPER meta. I mean I’m not even supposed to know who that lot are! That’s nearly as crazy as some Timeless Child being dropped at random somewhere in the wilds. Still sorted, innit?
DONNA Don’t say ‘Innit’, that's weird
(Another discontinuity, but only a little one this time: New Doctor & Tenth Doctor face off with Rose looking on)
10th DOCTOR: You were born in battle, full of blood and anger and revenge.
(to Rose) Remind you of someone? That's me, when we first met. And you made me better. Now you can do the same for him.
ROSE: But he's not you.
DOCTOR: He needs you. That's very me.
DONNA: But it's better than that, though. Don't you see what he's trying to give you? Tell her. Go on.
NEW DOCTOR: I look like him and I think like him. Same memories, same thoughts, same everything. Except I've only got one heart.
ROSE: Which means?
NEW DOCTOR: I'm part human. Specifically, the aging part. I'll grow old and never regenerate. I've only got one life, Rose Tyler. I could spend it with you, if you want.
ROSE: You'll grow old at the same time as me?
NEW DOCTOR: Together.
(The Tardis time motor revs.)
DOCTOR: We've got to go. This reality is sealing itself off for ever.
ROSE: But, it's still not right, because the Doctor's still you.
DOCTOR: And I'm him.
ROSE: All right. Both of you, answer me this. When I last stood on this beach, on the worst day of my life, what was the last thing you said to me? Go on, say it.
DOCTOR: I said, Rose Tyler.
ROSE: Yeah, and how was that sentence going to end?
DOCTOR: Does it need saying?
ROSE: And you, Doctor? What was the end of that sentence?
(The new Doctor whispers the three little words in Rose's ear, and she kisses him. The Doctor and Donna take the opportunity to get into the Tardis. It dematerialises.)
Notes
The Meta-Crisis Doctor was a Time Lord/human hybrid and a human incarnation of the Doctor, who possessed one heart, aged as humans did and had no regenerative ability to avoid death. He was created by an instantaneous biological meta crisis and was the final result of the Tenth Doctor's aborted regeneration.
On Christmas 2006, the newly regenerated Tenth Doctor lost his hand in a sword fight against the Sycorax leader. The Doctor's hand remained in the TARDIS until the Doctor was grazed by the blast from a Dalek gunstick, triggering the Time Lord's eleventh regeneration. After healing the damage to his body with the regeneration energy, he channelled the excess energy into his hand, a bio-matching receptacle, allowing him to heal but not change his appearance and personality.
Even though the regeneration was aborted before it could be completed, the fact that the Doctor siphoned off the energy that would've changed his appearance after healing his injuries, he used up the same amount of regenerative energy as a full regeneration. This, as the Eleventh Doctor later told Clara Oswald, meant that his previous incarnation used up two regenerations due to "vanity issues."
Shortly after this aborted regeneration, the Daleks attempted to destroy the Doctor's TARDIS. Still inside the TARDIS during this apparent destruction, Donna Noble touched the energised hand's container. The regenerative energies present within the hand combined with Donna's human DNA, causing an instantaneous biological Meta Crisis. The force of the reaction shattered the container, allowing the energy to regenerate the entire missing body of the Doctor. In this process, the "Meta-Crisis Tenth Doctor" was created. He immediately dematerialised the TARDIS, saving it and Donna.
However, this Doctor was born in a separate body than the original Doctor, existing as a separate person with DNA sampled from Donna Noble. These genetic alterations caused him to develop a unique, less merciful personality that deviated from the moral code that his counterpart followed. The Meta-Crisis Doctor was prompted to fulfil a prophecy by destroying the Daleks. He proceeded to overload the Dalekanium power feeds, causing virtually the entire New Dalek Empire to explode, from individual Daleks to the Crucible itself.
Feeling his new, part-human counterpart was too dangerous to be left to his own devices, the Doctor entrusted him to Rose Tyler, taking the two of them back to Bad Wolf Bay in Pete's World. The Doctor told Rose that his part-human self needed her, that he was angry and vengeful as he himself had been when he first met Rose. He told her she had made him better, and now she had to do the same for his other, part-human self. Rose objected to this at first, insisting that the new Doctor was not really him, despite the Doctor's assurance that they were the same man and the part-human Doctor offering to spend the rest of his life with her. Rose asked both Doctors what the last thing they had said to her was when they were originally standing on Bad Wolf Bay. The Doctor was unable to give her a direct answer: "Does it need saying?" She posed the same question to the part-human Doctor, who whispered it in her ear.
