- Ginny is Demoted to Extra over the next couple of books, during which time a lot of readers conjecture that she dealt with her own insecurities and the trauma of what happened to her in the previous book. Luna was probably somewhere in a similar process given that she had lost her own mother three years prior, and the two may have bonded over that (and perhaps even having to relive their respective awful experiences when in close proximity to the Dementors that had been posted around Hogwarts). Or maybe Ginny just stuck up for Luna at some point when the latter was getting bullied. It's casually mentioned in Book 4 that the Lovegoods "couldn't get tickets" to the Quidditch World Cup, indicating that the Weasleys were acquainted with them by that point in the story.
- We know the Ministry is not above abusing their authority over dementors to "take out" people they deem a threat. The two of them were colleagues and probably friends, and Lucius surely wanted revenge for Harry freeing Dobby and fucking up his plan to open the Chamber the previous year.

While there are plenty of dangerous and outright horrifying magical creatures present throughout the series, Dementors still stand out. They're one of a relatively small number of creatures that lack parallels in folklore and mythology, there are few (if any) other Emotion Eater species in the series' bestiary and, for most of the series, they seem to have a "wild" range restricted to a single small island in the North Sea. One that used to be the home of a dark wizard, Ekdrizdis, who built the fortress of Azkaban.
What, exactly, Ekrizdris was doing at Azkaban (other than trapping and horrifically murdering Muggles) is never described in depth. The people who first surveyed the island, after his poorly documented death, refused to describe whatever they found there. The place was just sealed off and left to molder until the community of witches and wizards in the UK opted to use it as a prison centuries later. No one wanted to risk offending the dark forces inhabiting it.
Had Ekrizdris just been performing sadistic torture or some set of cruel "experiments" there, then those who saw the results firsthand might not have been willing to go in-depth. They could have just left it at, "He was doing things I don't want to talk about to the people he captured", though. Whatever was going on at Azkaban in the 15th century really had to be dangerous, not just unspeakably terrible, and it likely involved the origin of the future guard of the UK's sole wizard prison.
Ekrizdris might have been creating Dementors from his captives, which the people who investigated his fortress probably wouldn't have wanted to report for fear that someone might repeat it in hopes of building an army. More likely, though, he was importing them. The idea of alternate Universes never comes up in Harry Potter. If they existed, though, at least one magic user would almost certainly find a way to bridge the gap between this world and one of its neighbors. Ekrizdris' descent into madness may have been born out of that. Neither his name, nor that of Azkaban, have obvious linguistic parallels in the area where he set up shop. He could have easily taken both from whatever plain he drew the Dementors from.
If the discoverers of Azkaban found out about a (thankfully closed) doorway to a place where Dementors were widespread, of course they wouldn't want to reveal that to the world at large. Better just to pretend that it never existed and take the secret with them to their graves, than to risk someone reopening that gate and letting something even worse through.
Since we find out in Book 7 that a part of Voldemort's soul is in Harry, we may very well be hearing Voldy's version of that night in the Potter house. There is no doubt that the worst moment in Voldy's life (at this point in the series) happened when he tried to kill Harry, and the part of his soul didn't latch onto Harry until he used Avada Kedavra on him. In addition:
- Harry was one year old at the time, so it's unlikely he remembers this in such detail;
- The narration of the memory (specifically in Chapter 12) is very similar to the narration in Chapter 17 of Book 7;
- In Chapter 1 of Book 5, Harry hears a new memory — the night of Voldemort's return — when the Dementors approach.
[WMG: if student Lupin Caste=school body=werewolves?]]I'm wondering if they had kept Lupin in the castle when he was turning into and being a were-wolf would there be a change that a high perecent of the student body (or even teachers) being turned into werewolves on the off-chance he escaped ?
