One mystery *partially* solved!

[caliburncy at yahoo.com]

I was reading the following CNN article:

http://www.cnn.com/2001/SHOWBIZ/Movies/11/22/hol.wkd.next.potter.film.
ap/index.html

and found further reference to the scene that Steve Kloves had to 
take out because JKR told him a future book would make it 
impossible.  For anyone, who isn't in the know, Kloves commented on 
this once before, but failed to disclose specifics.  Now there's some 
more specifics, but we still don't know much.  Here's the new CNN 
quote:

> "I wrote a piece of dialogue referring to Sirius Black," -- one of 
> the main figures in the third book -- and she said, 'you can't do
> that because you will see in book five, that's not possible,' "
> Kloves said. 

So we know now that it has something to do with Sirius Black.  
Interesting.  I assume then that it would have been brought up at 
some point in Hagrid's comments about where he got the motorcycle 
(per canon--these lines were either cut or never filmed for the 
movie).  So the new mystery is: what could Kloves have possibly said 
about Black that book five will make impossible?
