snazzzybird:

I've been wondering about these things too, specifically with regard 
to the incident when Sirius was speaking to Harry in the Gryffindor 
Common Room fire.  An instant after he left the fire, Umbridge's hand 
appeared, clutching at the space where his hair had been.  Sirius was 
speaking from #12 Grimmauld Place.  If Umbridge had gotten hold of 
his hair -- well, okay, he probably would have been able to get 
free.  But what if he hadn't?  If he had withdrawn his head from the 
fireplace with her hand still entangled in his hair, would she have 
been able to "trace the call" so to speak?  Might she have popped out 
into the kitchen of Order of the Phoenix headquarters -- a location 
which does not exist for her, because she has not been told about it 
by the secret keeper?

If so, the Fidelius Charm might have rendered her confused, groggy; 
Sirius could then have hustled her out to the front door and launched 
her onto the street.  Then as she wandered, in a confused state, 
along the streets, the charm might gradually lift, leaving her 
wondering "Where am I?  How did I get here?  Am I going mad?"  
Perhaps St. Mungo's would have been the next stop for the radiant 
Dolores.

Thoughts, anyone?
