Ebrien, I’ve thought for some time that Harry’s naming characters has some importance to the story.  Remember when Harry dropped “El” from Mr Sunshine’s name or when he shortened the Earlking’s name to Earl?  Those characters were quick to react and did not think the matter inconsequential.  Giving Toot and Demonreach names has had significant consequences.  I suspect Harry’s naming these characters gives him some ability to define their natures.

Having said that, returning to the thread topic, I prefer g33k’s concept that Harry is prescient to the idea that he is broadcasting his thoughts.  Broadcasting his thoughts, even if restricted to certain “sensitive” individuals, could be a distinct weakness for Harry.  And outside the phrase repetition, there is no evidence I can recall of Harry’s enemies knowing what he is thinking.  For example, none of Harry’s companions in Skin Game seemed to be aware of his arrangement with Goodman Grey.
