Jacob:[To Richard] Imagine that this wine is what you keep calling hell. There are other names for it. Malevolence. Evil. Darkness. And it's all down here swirling at the bottom. Unable to get out, because if it did it would spread. Now, the cork is this Island. [Puts a cork in the jug, trapping the wine] And it's the only thing keeping the darkness where it belongs.
