I've just done a rereading of the Half-Blood Prince and got a lot of 
questions from it. For one, does Snape know about the Horcruxes? I 
mean, he was the one to heal Dumbledore's hand. Snape must have been 
curious. Is it possible that Dumbledore could have told him? And I 
don't think that Dumbledore could have trusted Snape that easily 
just because Snape said he was remorseful for telling Voldemort 
about the prophecy. I wonder if Dumbledore knew something else about 
him that made him trust Snape so. 

Another question, on her site, JKR said that Neville had the same 
chances of being the "Boy Who Lived". If so, why did Dumbledore 
choose to protect the Potters? Why not the Longbottoms? Or were they 
protected also?

In Chapter 13, The Secret Riddle, on page 268, it mentioned the two 
kids, Amy Benson and Dennis Bishop, on the outing with Tom Riddle to 
the cave. I am really curious to know what he could have shown them 
that scared them so much. 

And while we're on Riddle, I have lots of questions about horcruxes. 
First of all, there's the potion in the basin. How would Voldemort 
have gotten the horcrux without the potion affecting him? Does he 
have an antidote or something? And when Dumbledore was drinking the 
potion, what did he see? What caused him so much pain and fear? And 
why didn't he just dump it over into the lake?

And of course there's R.A.B. How did he/she get the horcrux out of 
the basin? The same way as Dumbledore? And did R.A.B. succeed in 
destroying the horcrux?

Just curious,
