Kai: Just living on alone, without a purpose, is tedious.

Peter: Mistress, do you think they're dead?
Jill: Don't smile when talking about death!

Jack: Talk about this in public, and I'll beat you to death.
Kai: You don't have to threaten him like that. We have the army and police behind us... And if they ever knew you spread around this information, you'd probably be captured and simply disappear.
Keith: You just said the exact same thing with more words.
