Update: Discussion has moved on to a new thread.
After 61 chapters of Harry Potter and the Methods of Rationality and 5 discussion threads with over 500 comments each, HPMOR discussion has graduated from the main page and moved into the Less Wrong discussion section (which seems like a more appropriate location). You can post all of your insights, speculation, and, well, discussion about Eliezer Yudkowsky's Harry Potter fanfic here.
Previous threads are available under the harry_potter tag on the main page (or: one, two, three, four, five); this and future threads will be found under the discussion section tag (since there is a separate tag system for the discussion section). See also the author page for (almost) all things HPMOR, and AdeleneDawner's Author's Notes archive for one thing that the author page is missing.
As a reminder, it's useful to indicate at the start of your comment which chapter you are commenting on. Time passes but your comment stays the same.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).
If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.
In regards to the nearly empty vial left in Bellatrix's cell:
Back when we first saw the flask, I remember there being confusion over the point of leaving something foreign behind what was supposed to be "the perfect crime." It definitely came in handy once they were found out, but it didn't make sense to leave it behind when there was a serious possibility that they could have gotten away with it. I was thinking about the arc the other day when it (belatedly) occurred to me just what Quirrell might have been thinking.
Just before this point, we are told that in the MOR-verse, a prisoner stays in Azkaban until their sentence is up, even if they die. For those with life sentences, their corpse stays there until they need the cell. Furthermore, snake!Quirrell confirms that she's alone, and thus is the only live prisoner in her particular area. Therefore, it would be reasonable to say that after Bellatrix died, the Aurors would stop frequenting that particular area until the next time someone who does "worse than murder" needs to be locked up. Even then, it's possible that there are other empty cells, or (more likely) that the guards dispose of the older corpses first, for the symbolism if nothing else. So it seems probable that even after the guards return to frequenting that corridor, Bellatrix's cell would probably be left alone the longest.
Additionally, much ado has been made over the destructive powers that Dementors have on their surroundings. And Bellatrix, being considered the most evil person in Magical Britain after Voldemort "died," is in the very worst location, in close proximity to the nest of over a hundred Dementors.
Moreover, Dumbledore makes a point of stating that the titanium bars of the cage of the Dementor that is brought to Hogwarts were trueforged, since they would last longer than if they were created magically. He also notes that while the Dementor would start to degrade the cage, it would take longer than a day, possibly implying that the destructive field is strong enough to make the destruction of titanium within the course of a few hours a serious concern.
All of this leads me to believe that Quirrell’s reasoning was that if they had managed to pull off the perfect crime, the guards would have discovered “Bellatrix” dead from Dementor exposure in the morning. I don't see the guards investigating a cell very carefully—or at all, really—when a prisoner dies in such a natural way, so the vial being put in the corner and covered in the strip of cloth that "nearly blend[ed]" in with the wall would keep them from noticing that anything was amiss in a cursory glance. After that, the cell would have been left alone for a long period of time, very near to the majority of Dementors, with the flask possibly being magically created as well. In all likelihood, this would have resulted in there being no traces whatsoever by the time anyone else would have entered the cell, preserving the perfection of the crime.
And if the crime wasn’t as perfect as Quirrell thought? Then they have a clue left behind, one with all the earmarks of Voldemort, neatly diverting suspicion away from Harry.
It took you long enough, but you are still to be congratulated on having realized it before most.
Unfortunetly, like the rest, you're still stuck thinking it was a mere distraction. Ask yourself, what happened as a result? Who's plan benefited from it? Was it foreseeable?
Harry is still too young, his magic is still weak. He will need some more time before he can be the Hero and Leader Dumbledore and Quirrell wants him to become.
Suppose the rescue plan goes flawlessly. No one would be the wiser, until the time some Bellatrix-sightings or something similar ca... (read more)
