Potioncat:
It is such a big difference! I thought it was only the first part 
that was different. That JKR allowed the change for any reason---and 
didn't make sure it was done in both---makes no sense. 


The other very interesting line that appears in both, is that Lucius 
is **safe** in Azkaban. Anyone think Mundungas went to Azkaban for a 
reason? Impersonating an Inferi---Really!
