"special fan" ...fact or fiction?

[GKJPO]

Did anyone ever find the reference to the "special fan" of Harry's 
being the death in OoP?  I looked through all the interviews I could 
find with JKR and never found a reference.  The only factual 
reference I have found is that the death is painful to write.  That 
means to me either that a. the circumstances of the death are painful 
or b. the character that dies is special to JKR.  It also makes a 
difference when folks are guessing who the death will be.

If someone did find the interview with the special fan quote, could 
you please post the reference?

Thanks
Kristen
