We can't stay here.
[Two Doctors. Neither is happy. Both are in the lab, though clone!Ten is working and original!Ten is mostly glowering at him from the other side of the workbench with his hand held against his diaphragm area.]
Oh, well I'm glad you've arrived to sort that out for me then, I hadn't noticed.
[Clone is silent, continuing to work. The original speaks up again.]
This isn't going to work.
Maybe not, but it will make a point.
And, what point would that be, exactly?
That you can't just... Steal people from their lives and put them in a box to play with. I'd have thought you'd have learned that from experience, or was four times not often enough?
You don't eve- We don't even know if any of this will send people back home! Normally a bit of experimenting and guesswork is fine, but this is too many people!
Collateral damage.
Are you insane? It's a city of people! You can't do that! I'm telling you, it won't work. It's a permutation of a single one out of the hundred scenarios I've already tested - you honestly think either of us could have just... Sat here for months now and not tried to get back home? Especially after they left?
I think you wouldn't have tried everything. Too worried about the outcome, too scared to do anything of any great importance after Bowie Base One.
[Extraordinarily tense silence. Like that hasn't been permeating the entire conversation anyway.]
Tell me I'm wrong.
[Beat.] There's better equipment in the TARDIS.
... Seriously? Really. At least be imaginative.
[Another silence. Clone continues to work; Original is mostly watching the motions absently, like people stare into fireplaces. He gets up and starts to leave, banking on either one or two out of three possible choices.]
Maybe I was - am scared. But that could be a good thing. So long running around, telling myself I wasn't, laughing about it, saving people and not looking back, or ever even returning to see how they were... And then scared of dying, even though I know it doesn't mean that. We even were dying. Maybe that's what this is for. [He has no idea. but if it isn't for something then this mild revelation is worthless, so, he hopes.] Realising that.
What?
[Ahh, choice one.] It's... Not a bad thing. The fear. Yeah, sure it's worrisome at the time, but the fact that it's there... I lost it. Then over-compensated, and look how that turned out. Jump out a spaceship and exterminate a race. Again.
Possibly the third time, depending on how you look at it, really.
Yeah, thanks. I do actually remember. [Yeah, he's leaving again, back to the TARDIS. This hand hurts a lot and he doesn't feel like dealing with this facsimile anymore.] You're right, we can't stay here.
[Clone!Doctor speaks in this colour. Original!Doctor speaks in this colour.]
[By the time the original had turned and left and went back to the TARDIS, the clone was banished, although the Doctor won't know that instantly.]
