Kolya: As a soldier you were a threat. If anyone was to use force to secure the repository, it would have been you, the military man. So I connected with your mind to distract you.
Sheppard: Distract me. Making me think the jumper had been sabotaged would have been enough of a distraction.
Kolya: You would have discovered the subterfuge. I am unable to maintain a static illusion over time. It was necessary to keep your mind occupied.
Sheppard: And that's what you chose.
Kolya: What you chose, I didn't have full control over your hallucination, or the direction it took. It was your mind driving the diversion. I merely played along.
Sheppard: You're saying I tortured myself.
Kolya: You torture yourself every day, John. But in this case it was your mind manifesting your darkest fears. You were the architect of your own self-deception.
