Arthur: Where were you? What happened to you? Cobb: Got blocked by a freight train. Arthur: Why would you put a train course in the middle of a downtown interface? Ariadne: Why, I didn't. Arthur: Where did it come from? Cobb: Let me ask you a question, why the hell were we ambushed, huh? Those were not normal projections. They've been trained, for God's sakes! Arthur: You're right. Ariadne: How could they be trained? Arthur: Fischer's had an extractor teach his subconscious to defend itself, so, his subconscious has militarized. It should have shown in the research. I'm sorry.
In the workshop on the first dream level Arthur, Cobb and Ariadne discuss the unexpected occurrences they just encountered.
