Cobb: "You create the world of the dream. We bring the subject into that dream and fill it with their subconscious."
Ariadne: "How could I ever acquire enough detail to make them think that it's reality?"
Cobb: "Well, dreams, they feel real while we're in them right? Its only when we wake up then we realize that something was actually strange."

Ariadne: "Why is it so important to dream?"
Cobb: "Because, in my dreams we are together."

"These aren't just dreams, these are memories and you said never to use memories!"

"You mind telling your subconscious to take it easy?"

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."

Ariadne: "My subconscious seems polite enough."
Arthur: "Well wait, it'll turn ugly. No one wants to feel someone else messing around their mind."

"Do you think you can just build a prison of memories to lock her in? Do you really think that that's gonna contain her?"
