Yes, sir. [Now he's just being a smartass.]
Not entirely true. This prison is a simulation, there are at least two engineers who have more to do with the prison's operation than the wardens do, and I have ideas about how we came to be here. No one can guess at why we are being held. I think it has nothing to do with rehabilitation. [He'll elaborate, of course, but it's a lot to accept.] I have been taking notes, if you would like to see them.
