I read that too.. although at the end of the film it does imply that he's no longer cured. I gather the book goes into that a bit further. I love the dialogue. Genius. Kubrick is the only director IMO my opinion who betters Tarantino when it comes to scenes made enjoyable just by the dialogue. Having not read the book yet it may be that most of this credit is due to the book's author Anthony Burgess.
