Pam queries:
This is tangentially related, but I have questions about consistency 
in the canon re: use of apparition: In OOTP, Dumbledore says that he 
put an "anti-apparition" or some such block on the Death Mystery 
room (those rooms & all those doors always remind me of the "Mystery 
Date" game)--BUT,  Bellatrix *runs* out of the room, and *takes an 
elevator* to the main hall.  Why couldn't she just apparate to the 
main hall? OR if DD had already placed the block on the Mystery 
room, why not apparate once she was out of the room?  Is is because 
she somehow knew that Harry would follow her? But how could she know 
that?
