Chapter 38: Lucius Malfoy claims that he was under an Imperius curse cast by Lord Voldemort. In canon, that claim was made by many powerful pureblood lords.

Chapter 26: Freeing someone from an Imperius curse by killing the caster of that curse creates a debt

Chapter 4: Bounties payable to the killer of Lord Voldemort could be delivered to Harry Potter.

Conclusion: Harry Potter is owed a blood debt by a number of the lords of the Wizengamot, which might be large enough that he could call it in and save Hermione. Even if it is just Lucius who owes him this debt, it could be enough.

Comments: Law of Conservation of Detail leans towards these facts being used, feels very desperate and Harry like, allows Hermione to come back to Hogwarts as a student.

Hermoine is still on the hook in the eyes of Draco and everyone for murder. I believe the story demands a fully vindicated Hermoine to continue, which is why I think Harry will frame Lord Jugson for the false memory charms on Draco and Hermoine. I go into further detail on this elsewhere, just check my comment history.

I don't think that Hermione needs to be fully vindicated for the story to go on. Having her be ruled innocent by the Wizengamot, possibly with a later recantation by Lucius Malfoy once he calms down, would have her be distrusted by her classmates somewhat. This could fit in nicely with her character development and her fear of becoming dark.

What False Memory Charm on Draco? I thought the current leading theory was that Hermione was GHD Attacked, FMC'd, then later on (after the attack?) Obliviated of the FMC. I don't see how Draco needed to be messed with at all.

This would be if they were stunned immediately on entering the trophy room, like Harry said we don't even know if a duel took place. Granted he could have just waited until after the duel and stunned Draco from behind, both would look the same to us.

Now that I think about it I actually like your way better, cloak and hat is there invisibly and makes sure Draco wins the duel, then stuns Draco while he is leaving. Less work to do with the False Memory charms, less work to do with tampering the wands, and less chance of messing up on evidence since an actual duel was fought.

What makes you sure that Hermione didn't stun and Blood-Chill Draco herself?

If by "herself" we mean without being Imperiused, Confunded, Dark-ritualed or otherwise having her mind directly messed with, it's because we've been inside Hermione's mind enough to know that she wouldn't murder a classmate.

Human beings have characteristics just as inanimate objects do.

Maybe we have different standards, but the Groundhog Day Attack and (at least) one False Memory Charm is quite enough mind-messing for me to believe she did it.

ETA: just to make it perfectly clear, I don't think this value of "she did it" is the sort that should require her to be held liable in a criminal trial. I just meant that the Stunner and Blood-Chilling Charm came out of Hermione's wand while she was holding it.

I still can't figure out whether you're excluding the Imperius.

Miss Granger would remember the Imperius. Obliviation cannot be detected by any known means, but only a Professor could have cast that spell upon a student without alarm from the Hogwarts wards

chapter 79

'She was Imperiused and then Obliviated' looks like the likeliest hypothesis right now.

I think the idea is that with just an Imperius and an Obliviation, she wouldn't remember herself deciding to cast the Blood-Chilling charm -- she might remember doing it, but not remember deciding to do it, which would be difference enough to be noted by the Veritaserum and/or Legimancer.

So you'd need the False-Memory-Charm on top of that, and once you have the False-Memory-Charm you don't actually need to complicate this further with an Imperius and Obliviation, it suffices by itself.

If that were true, it'd be really easy to detect an Imperius by examining the subject's memories... The subject wouldn't remember deciding to do anything the Imperius made them do. [Test Foo]

Instead, McGonagall's statement implies that the best way to figure out whether the subject was Imperiused is to see if they remember being Imperiused, even with all the information that would allow you to perform Test Foo.

Then again, McGonagall's speaking outside her area of expertise.

I don't think a False Memory and whatever persuasive words were used in the Groundhog Day attack would have sufficed for her to cold-bloodledly murder a 11-year old classmate, even if she had seen him openly declare a desire to rape Hannah Abbot. (she might have hot-bloodedly murder him then, but not cold-bloodedly so).

I think you underestimate the power of the GHD. If Hermione really believed she had to kill Draco or he will, for example, murder every student in Hogwarts the next day, I'm pretty sure she would cold-bloodedly kill him.

Okay. How about we take up this discussion again in, let's say, thirty-five hours?

Comment author: ArisKatsaris 26 March 2012 09:03:09AM 0 points [-]

Sure. :-)

If it were, one could argue that Harry's certainty re: the false-memory charm deliberately fools the reader.

Comment author: pedanterrific 26 March 2012 07:51:48AM 2 points [-]

I don't understand what you mean. Harry believes she was FMC'd into obsessing over Draco and believing he was plotting to kill her. That's quite sufficient to drive her to murder, without it actually being her fault.

Comment author: magfrump 26 March 2012 11:11:32AM 3 points [-]

A big deal has been made about Hermione's innocence; i.e. Harry's extensive thoughts on the Milgram experiment after Azkaban. The implication seems to me to be that no, that is definitively NOT sufficient to drive her to murder; in fact, nothing would be sufficient to drive her to murder.

Comment author: pedanterrific 26 March 2012 07:07:57PM 4 points [-]

I guess Harry is sure of this fact due to his infallible power to know the hearts of men (and little girls).

I think Harry's wrong about that, is what I'm saying.

He also believes that performing the Blood-Cooling Charm was a false memory. (At least that's how I understand the following quotes from ch. 79.) I'll admit however, that the evidence is not as clear as I thought, when I wrote the previous comment.

"Draco didn't do anything, Hermione didn't do anything, they were both False-Memory-Charmed!" Harry Potter's voice had been rising on the last words. "How is that not BLOODY OBVIOUS?"

[…]

"Ah!" Harry said suddenly. "I get it now. The first False Memory Charm was cast on Hermione after Professor Snape yelled at her, and showed, say, Draco and Professor Snape plotting to kill her. Then last night that False Memory was removed by Obliviation, leaving behind the memories of her obsessing about Draco for no apparent reason, at the same time she and Draco were given false memories of the duel."

Oh, you're right, I misremembered Harry's proposed scenario in the second quote.

Yeah, on balance I think that the duel actually happened and Harry's suggested second round of FMCs is unnecessary- that just comes down to Harry not being willing to believe that Hermione is capable of cold-blooded (ha) murder, even in that state of mind.

To be honest, I doubt she is.
