“Rose Tyler: The time war ends.
Emperor Dalek: I will not die! I cannot diieee!
[we see Rose's eyes light up, and the Dalek Emperor and his entire fleet disappear in an explosion of golden dust]
The Doctor: Rose, you've done it, now stop.
[Rose stares straight ahead]
The Doctor: Just let go.
Rose Tyler: How can I let go of this? I bring life.
[we see Jack start breathing again and open his eyes]
The Doctor: But this is wrong! You can't control life and death!
Rose Tyler: But I can. The sun and the moon, the day and night... but why do they hurt?
[she is crying]
The Doctor: The power's gonna kill you and it's my fault!
Rose Tyler: I can see everything... all that is... all that was... all that ever could be.
The Doctor: [stands up] But that's what *I* see. All the time. And doesn't it drive you mad?
Rose Tyler: [Rose nods, barely able to speak] My head...
The Doctor: Come here.
Rose Tyler: ...is killing me.
The Doctor: I think you need a Doctor.
[He leans down and kisses her, and the golden light transfers from her to him through their lips]”

“ Dalek Sec: The Doctor will open the Ark!
The Doctor: Ha ha, the Doctor will not.
Dalek Sec: You have no way of resisting!
The Doctor: Mm, you got me there. [withdrawing the sonic screwdriver] Although, there is always this.
Dalek Sec: A sonic probe?
The Doctor: [with jocular bravado] That's screwdriver.
Dalek Sec: It is harmless.
The Doctor: Ohh, yes. Harmless is just the word: that's why I like it! Doesn't kill, doesn't wound, doesn't maim. But I'll tell you what it does do: It is very good at opening doors. [He pushes the switch and the doors explode inwards; Jake's squad and some Cybermen run in and open fire.] ”

“Cyber Leader: Daleks, be warned. You have declared war upon the Cybermen.
Dalek Sec: This is not war - this is pest control!
Cyber Leader: We have five million Cybermen. How many are you?
Dalek Sec: Four.
Cyber Leader: You would destroy the Cybermen with four Daleks?
Dalek Sec: We would destroy the Cybermen with one Dalek! You superior in only one respect.
Cyber Leader: What is that?
Dalek Sec: You are better at dying.”

“Rose:i love you
