More COS clues: Dobby related

No: HPFGUIDX 111815

After reading all the theories on the clues in COS that JKR hints at 
in several interviews and on her web site, I decided to re-watch the 
movie--I had already re-read the book recently, looking for some of 
the clues.  Most of them have been mentioned and discussed on the 
Book Two Discoveries (#111511).

So one of the things that seems prominant in both the book and the 
movie are the powers that Dobby has.  We've already talked about his 
ability to do wandless magic, seemingly apparate and disapparate 
(even in Hogwarts), he enchants a bludger, seals the entrance to the 
Hogwarts Express, and purloins all of Harry's summer letters.  Even 
though he isn't supposed to leave his family's house, he does--to 
warn Harry several times.

One of the things I've been looking for is something that was in the 
movie that was definitely not in the book--because at one point JKR 
mentions there is something that foreshadows the future books and 
that she ok'd it.  I think I have found it, and wonder why I never 
noticed it before.  Here it is:

In the book, after Harry has returned the damaged diary to Lucius 
inside the sock, Lucius throws it at Dobby, (thereby freeing Dobby).

Ch. 18, p. 338, US hardback:

"You'll meet the same sticky end as your parents one of these days, 
Harry Potter," he [Lucius] said softly.  "They were meddlesome 
fools, too."

He then turns to leave, telling Dobby to come along, but Dobby has 
the sock and says:

"Master threw it [the sock], and Dobby caught it, and Dobby--Dobby 
is FREE."

Lucius Malfoy stood frozen, staring at the elf.  Then he lunged at 
Harry.

"You've lost me my servant, boy!"

But Dobby shouted, "You shall not harm Harry Potter!"

There was a loud bang, and Mr. Malfoy was thrown backward.  He 
crashed down the stairs.....

"You shall go now," he [Dobby] siad fiercely, pointing down at Mr. 
Malfoy.  "You shall not touch Harry Potter.  You shall go now."

So, what's the difference in the movie that I think is a clue?  
Harry slips the sock in the diary and Malfoy hands it to Dobby--a 
little different, but essentially the same.  When Malfoy realizes 
that Dobby has been freed, he PULLS OUT HIS WAND, points it at 
Harry, and says something that sounds like  "Avada", then is blasted 
off his feet by Dobby before he can finish the curse. The rest is 
similar to the book.

Now, what I am wondering is about the part that shows that Dobby can 
stop the avada kedavra curse with whatever that powerful magic is 
that house elves have, when many wizards aren't able to do it. Of 
course, Lucius didn't complete the curse, but Dobby was quick enough 
to prevent that.  Whenever we see the use of the AK, the wizard or 
muggle seems to be paralyzed and unable to do anything to prevent 
the completion of the curse--and at that point there is no fighting 
against it.  Even Harry and Cedric are unable to do anything about 
it in the graveyard in GOF.  Is this some sort of foreshadowing that 
the house elves--or at least, Dobby, will be instrumentlal in aiding 
Harry in the future?

In both the book and the movie, the short conversation that Harry 
has with Dobby after that is full of Dobby thanking Harry for 
freeing him, and Harry asking Dobby to "promise never to try to save 
my life again."

And in both, Dobby smiles, but doesn't say anything.

Ideas?  Thoughts?
