(Thanks again to my elf for watching over me as I am new to posting 
(an old hand at lurking) and letting me know if this has been 
covered a thousand times...

Was Fudge possible forshadowing the return of Sirius?  I know thats 
not a popular theory but wait, I think he's gone for good too then 
this...  American edition page 614

"Or was it Potter's identical twin in the Hog's Head that day?  Or 
is there the usual simple explanation involving a reversal of time, 
a dead man coming back to life, and a couple of invisible dementors?"

Fudge was talking to DD and it seems he knows about the time turner, 
believes Harry made up the dementor story (canon pg 142), and is 
maybe foreshadowing the return of a dead man?  Or as I'm typing this 
it just occurred to me he's probably talking about Lord Thingy.  But 
could it be Sirius?
