Hurrah canon-based cures, right? I would think that anything that can manage data repair -- or whatever a Milliways-equivalent "healing" spell might do from someone who knew the nature of the sprite-being they were dealing with -- would be effective in restoring Bob or Enzo or Dot or whoever might end up crossing Blodwen, should that event come to pass.

(I did see at least some of the discussion between Bob and Enzo a while back, and am intrigued!)
