CH3ed:
I haven't been able to keep up with the sheer volume of posts so 
this might have been discussed already. Sorry in advance. 

Talk about clues that might have been in OotP. Has anyone come up 
with a good guess of where AlbusD really went when he went away 
after Umbridge took over? Beside looking for Voldy's horcruxes? I'm 
tempted with Hermione's cover story of him being at a bar when 
Umbridge caught Harry using her floo outlet (it's rather humorous if 
it turned out AlbusD was hanging out at his brother's pub all that 
time).  

Also... what exactly caused the Headmaster's office to seal itself 
when AlbusD fled and Umbridge took over? Seems the Minister of Magic 
get to appoint Headmaster... so wouldn't the Minister's edict be 
able to overrule the zeal? Or is that one of the Founders' 
little 'rebellion' magic? If Umbridge had been able to get inside 
the Office and ask the portraits where they thought AlbusD went, do 
you think they'd be bounded by honor to tell her (since she was the 
official Headmistress)?

CH3ed  :O)
