"Seven! Isn't it bad enough to think of killing one person? And in any case ... bad enough to divide the soul ... but to rip it into seven pieces ..." -- Horace Slughorn
Harry learns that Dumbledore has returned, races off to his office. Together they watch Slughorn’s memory, where Riddle learns what Horcruxes are and contemplates making more than one. Dumbledore explains his suspicions that Riddle made six, including the now-destroyed ring and diary, the locket, the cup, and Nagini. Dumbledore promises Harry can join him in destroying the next one, and explains to Harry what love – and the prophecy – really mean.

Interesting facts and notes
"Oh, groaning and clanking up on the Astronomy Tower, it's a favourite pastime of his -"
Interesting favourite pastime of the Bloody Baron's
"Come back! All right, I lied! I was annoyed you woke me up! The password's still 'tapeworm'!"
Apparently the Fat Lady can deny entry into the Common Room even if a person knows the password.
Slughorn looked deeply troubled now: he was gazing at Riddle as though he had never seen him plainly before and Harry could tell that he was regretting entering into the conversation at all.
One wonders if Slughorn treated Tom Riddle differently after this conversation or not.
Exceptional character moments
Harry finally understands that he does not have to fulfill the prophecy. It is his choice and because he loves his parents he wants to avenge them.
It was, he thought, the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high. Some people, perhaps, would say that there was little to choose between the two ways, but Dumbledore knew - and so do I, thought Harry, with a rush of fierce pride, and so did my parents - that there was all the difference in the world.
