“ 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.] ”
