Hi y'all, long time lurker here, I haven't posted in *years* - usually 
the threads end up all philosophical and deep and while I love to read 
them and learn, I never feel like I can add much....anyway...on to the 
post:

So I'm listening to the CDs of DH and Harry and Luna are in the 
Ravenclaw common room. Carrow and Minerva come in (after Electo is 
stunned) and Carrow says that they (the Carrows) had been tipped off 
that Harry may try and come into the Ravenclaw common room.  Now 
perhaps this is just something I forgot from my initial read of DH, 
but *why* would Voldy think that Harry would be going to the Ravenclaw 
room?  He would have had to share that knowledge with the Carrows 
before setting off on the Horcrux Double Check mission.

I got another question too, but I'll post to another thread. Wait for 
it.
