The Doctor: I still don't know what you need me for?
Dalek Sec Hybrid: Your genius. Consider a pure Dalek. Intelligent but emotionless.
The Doctor: Removing the emotions makes you stronger. That's what your creator thought, all those years ago.
Dalek Sec Hybrid: He was wrong.
The Doctor: He was what?
Dalek Sec Hybrid: It makes us lesser than our enemies. We must return to the flesh and also the heart.
The Doctor: Then you wouldn't be the supreme beings anymore.
Dalek Sec Hybrid: That is good.
Dalek Caan: That is incorrect!
Dalek Thay: Daleks are supreme!
Dalek Sec Hybrid: No! Not any more!
Dalek Caan: But that is our purpose!
Dalek Sec Hybrid: Then our purpose is wrong! Where has our quest for supremacy led us? To this: hiding in the sewers on a primitive world. Just four of us left. If we do not change now, then we deserve extinction.
The Doctor: So you want to change everything that makes a Dalek a Dalek.
