Somewhere in Order of the Phoenix (I can't find the page number, 
please help me)  Ginny is talking to Harry about being possessed by 
Voldemort and losing conciousness for hours at a time.  The 
words "Harry's heart began to soar."  is written.  Is this a typo.  
Is Harry's heart sore because his body is being manipulated by the 
Dark Lord or is his heart begining to soar because he is happy?  It 
would make more sense if he was sad with being controlled by a 
murder who killed his parents.  Why would his heart be soaring?  
Even if he does feel for Ginny, he would not be happy with the 
particular conversation.
