See - I told you we'd be seeing Doug again! You did remember he could fly, right?
One of the big problems in posting a long-form comic like Shades on the web is the long time that can pass between reading pages. If you were reading this in book form, you'd probably have read that information less than half an hour ago. As it is, it's probably been some months since you read about Doug's "transformation".
But don't worry - if you didn't remember, you can always take a sneaky peek back at Chapter 5 Page 11 now (Panels 5 - 8 if you need really precise directions!) That'll tell you everything you need to know!
I hadn't thought about it before but I think this is the first page where we see our three main heroes (Boo, Doug and the Shaman) together. I guess those plot threads really must be converging at last!
