Stephanie: I wouldn't mind a sister either
Tanith: Any chance of that happening?
Stephanie: I can't see what would be in it for my parents. I mean, they have the perfect daughter already - What more could they want?

Stephanie: Why can't you break in? You broke into the Vault
Skulduggery: That's different
Stephanie: Yes, it had alarms and vampires - this'll be so much easier
Skulduggery: There are times when extreme measures are unnecessary
Stephanie: Extreme measures are very necessary here!

Skulduggery: The fate of the world may depend on whether or not you can bring yourself to visit your relatives
Stephanie: It may depend
Skulduggery: Valkyrie--
Stephanie: Fine I'll go -
Skulduggery: Being a detective isn't all about torture and murder and monster. Sometimes it gets truly unpleasant.

Cheer up everyone, since we're all going to die horribly anyway, what's there to be worried about? - Skulduggery Pleasant.

You can only anticipate what someone is going to do if you know know exactly what that someone has just done - Skulduggery Pleasant.

Serpine: Well, Skulduggery? Where is that tired old defiance - the taunting, the goading? Where are the endless heroic clinches? Aren't you going to look me in the eye and tell me to do my worst?
Skulduggery: Actually, I was going to ask that you go easy on me. I'm feeling kind of tender today
Serpine: This is your one chance. Tell me where the key is
Skulduggery:OK
Serpine: Really?
Skulduggery: No, only joking. Do your worst.
