Cobb:
What is the most resilient parasite?...A bacteria?...A virus?...An intestinal worm?

Arthur:
Uh....What Mr. Cobb is trying to say...

Cobb:
An Idea...Resilient. Highly contagious. Once an idea has taken hold in the brain, it's almost impossible to eradicate. An idea that is fully formed, fully understood, that sticks. Right in there somewhere.

Saito:
For someone like you to steal?

Arthur:
Yes. In the dream state, your conscious defenses are lowered and it makes your thoughts vulnerable to theft. It's called extraction

Cobb:
Mr. Saito, we can train your subconscious to defend itself from even the most skilled extractor.

Saito:
How can you do that?

Cobb:
Because I am the most skilled extractor. I know how to search your mind and find your secrets, I know the tricks and I can teach them to you so that even when you're asleep, your defense is never down. Look, if you want my help, you're gonna have to be completely open with me. I need to know my way around your thoughts better than your wife, better than your therapist, better than anyone. If this is a dream, and you have a safe full of secrets, I need to know what's in that safe. In order for this all to work, you need to completely let me in.

[Saito stands up from table]

Saito:
Enjoy your evening, Gentlemen, as I consider your proposal.

[Saito walks away]

Arthur:
He knows. Saito's playing with us.

Cobb:
It doesn't matter. I can get it.

[Environment begins to shake]

Arthur:
What's going on up there?
