Mal: "What are you doing here?"
Ariadne: "My name is..."
Mal: "I know who you are. What are you doing here?"
Ariadne: "I'm just trying to understand..."
Mal: "How could you understand? Do you know what it is to be a lover? To be half of a whole?"
Ariadne: "No..."
Mal: "I'll tell you a riddle. You're waiting for a train. A train that will take you far away. You know where you hope this train will take you; but you don't know for sure. But it doesn't matter. How can it not matter to you where that train will take you?"
Cobb: "Because you'll be together."
