I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Neither Bren nor I have any idea about what's going on. At this point, I think that either something has happened at Mospheira that Tabini is trying to keep from Bren (does man'chi work in reverse?), or Tabini is testing Bren's loyalties (would atevi do that, though?). I still feel like I have huge gaps in my understanding of how atevi minds work, which isn't helped by Bren constantly doubting his own interpretations.
Please let the ending at least clarify what's going on with all the assassination attempts.
