little thing in COS

[fanofminerva]

I was reading on JKR's website (catching up is more appropriate) and 
read her answer to a question about the half blood prince and its 
relation to the chamber of secrets.  Let me put a quote in here from 
her website then ask my question:

"The link I mentioned between books two and six...relates to a 
discovery Harry made in 'Chamber' that foreshadows something he 
finds out in 'Prince.'"

In an interview (sorry, I don't have the link), JKR mentioned 
somethig small being included in the movie COS because of the 
bearing it had later in the story.  (This was discussed on the main 
list a few months back.)  Does anyone else share my opinion that 
this something small that was included in the movie is the 
foreshadowing JKR stated in her answer?  If so, any suggestions as 
to what this might be in light of the title "The Half-Blood Prince" 
(which was not known when this was discussed on the main list)?
