Finwitch:

How does Dumbledore know? How has he always appeared to know 
everything? I thought OOP gave us the answer: Legilimency. Since 
Dementors can drag the memory from Harry years after, when Harry - 
due to being so young - has forgotten all but green light - and a 
laughter brought up when Hagrid told him the truth - why couldn't 
Dumbledore do a quick Legilimency on Harry to confirm how things 
were? Of course, if it wasn't what he thought, he would have taken 
care of Harry himself or something...

Hmm-mm. Think of this: 'The twinkling light that usually shone from 
Dumbledore's eyes seemed to be gone out.' (PS end of the Boy Who 
Lived, page 17 in my book). and this, as far as I remember, is the 
ONLY time Dumbledore's eyes don't *twinkle*.

Now that we know about Legilimency/Occlumency, (and how JKR uses the 
word *seem* in the books, well...) if that twinkle is Dumbledore's 
Occlumency-shield, it was gone because he had let it down in order to 
do Legilimency on Harry -- OR Harry's infant, uncontrolled magic had 
just rejected Dumbledore's Legilimency with similar mirror-effect we 
saw when Snape was giving Harry Occlumency-lessons (leaving 
Dumbledore a bit defenceless for that brief moment).
