Not a full-blown chapter, so, don't count it toward the events promised in chapters 19-21. ;) Not much plot advancement, either. Just a scene I thought of after posting chapter 20, that wouldn't have really fit into chapter 21. Hopefully, 3-4 pages of Eriko yakking it up won't bore you all. XD
Although...I'm actually considering the possibility of having more interludes, and possibly breaking "chapters" into smaller sections, dividing content into smaller but more frequent updates.
