Have you ever heard the phrase "Rich as a Lannister?" Of course you have. You're a smart man. You know who the Lannister's are. I am a Lannister. Tyrion, son of Tywin. Of course, you have also heard the phrase, a Lannister always pays his debts. If you deliver a message from me to Lady Arryn, I will be in your debt. I will owe you gold. If you deliver the message, and I live, which I very much intend to do.

Tyrion
