I wrote a minor revision for chapter 6 to explain why Jean wasn't wearing any clothes when he met Gregor.
If you already read chapter 6 then you can read the revisioned part here:
After he got over his initial shock he felt his skin, it felt baby smooth now and he kinda liked the feel of it. Jean was about to put on his bathrobe and boxer shorts again when he decided against it. His boxer shorts felt soiled and his bathrobe regularly made him trip when it got stuck under his knees. He was fed up with his lack of clothes, but his current wardrobe wasn't helping him much either. Jean felt really wicked as he made up his mind to walk around naked in the maze. For all he knew he was alone in this place any way, he hadn't encountered another soul yet.
The doctor later also asks Erik to get rid of these clothing articles with help of the cleaning robots.
Other news; I've had a lot of ideas for chapter 7 already and started writing that chapter last night. Maybe I can even get it done tonight already, otherwise it'll likely be up either Tuesday night or Wednesday evening. (European nights btw, so American middays.) ;-)
