snicker I loved the ending, I wonder who was more surprised< Binns or the students that thought they had Peeves? I did love Harry's reasoning for his summer study and I thought it valid; 'twould be -real- interesting to eavesdrop on Dumble's thoughts upon hearing this, esp. since he does know the prophecy and this -is- one power that Harry could use and Tom never could.
In any case, a good chapter that develops the various threads of the storyline with a suitable levening dose of humor along the way.
