I could be confused on that too ... I briefly ran through some fairly terrible scanlations of Gaiden at one point, but I'm really confused about what happened between the current chapter on saiyuki_manga and the recent ones where Kenren was fighting the monsters (with results as we all know, to our sorrow). I know Tenpou, Konzen, and Kenren were talking politics during the time in the library (?), and I probably missed something.
