They've Mutated again

Dalek Mutant Attacks the Doctor | Remembrance of the Daleks | Doctor Who

Time's Champion : 

.... They've mutated again. Here, come and have a look. 

Compare that to the destroyed Dalek 

at Totter's Lane. Note the difference.

RACHEL: 

The other Dalek was underdeveloped, with vestigial 

limbs and sensory organs almost amoeboid. 

Allison, look -- This is altogether different. 

It has functional appendages and some kind of 

mechanical prosthesis grafted onto its very body. 

.....I think I'm going to be sick --

(Boom.)

Time's Champion : 

Sergeant Smith must have 

found some more Daleks.

ACE! : 

Don't anyone give me a hand.

ALLISON: 

Ace, you're hurt --

ACE! : 

I had an argument 

with a window --

Time's Champion : 

You two go down and check the cellar, 

but don't touch anything --
I'll look after Ace.

(Rachel and Allison leave.)

....(sigh) When I say 'stay put', I mean 'stay put', not 'take on 

an entire Dalek assault squad single-handed' -- 

(he begins manipulating and healing her injured leg)

What were you doing here, anyway?

ACE! : 

I came to get my tape deck.

Time's Champion : 

Where is it?

ACE! : 

In little bits.

Time's Champion : 

Good.

ACE! :

  Good?! Ow. What do you mean,' good'?!
Where am I going to get another one?

Time's Champion : 

That tape deck was a dangerous anachronism. 

If someone had found it and discovered The Principles 

of its function, the whole microchip revolution 

would take place now, twenty years too early, 

with incalculable damage to The Timeline....

ACE! : 

So?

Time's Champion : 

'So"? Ace, The Daleks have a mothership up there 

capable of eradicating this planet from space -- 

but even They, ruthless though They are, would think twice 

before making such a radical alteration to The Timeline.

(The Doctor finishes check Ace's leg then tweaks her ear.)

Time's Champion : 

There, you ought to be able to 

get up and walk about now.

(she stands up, and it has worked)

ACE! : (smiles)

 Cheers, Professor!

[Mothership]

DALEK Watch-Commander : 

Bridge reporting. Mothership will maintain Earth geostationary orbit. 

All systems fully operational. Attack squad Delta prepare to enter Transmat.
