Cersei Lannister: There must be someone at the Iron Bank you can speak to, come to some arrangement.

Tywin Lannister: The Iron Bank is the Iron Bank. There is no someone.

Cersei Lannister: Someone does work there. It is comprised of people.

Tywin Lannister: And a temple is comprised of stones. One stone crumbles and another takes its place. And the temple holds its form for 1,000 years or more. That's what the Iron Bank is... a temple. We all live in its shadow and almost none of us know it. You can't run from them. You can't cheat them. You can't sway them with excuses. If you owe them money and you don't want to crumble yourself, you pay it back.
