Lucius Malfoy's eyes narrowed. "By the report I received, you cannot cast the Patronus Charm, and Dumbledore knows this. The power of a single Dementor nearly killed you. You would not dare venture near Azkaban in your own person -"

Has Lucius not spoken to Draco in private yet?

If he hasn't... when he does, and tells Draco what happened at the trial, and finds that Draco isn't surprised (or at least, not more than usual when it comes to Harry)... what will he think then?

Even if he knew, saying that would be a good way to try to get Harry to reveal something. What he would have heard from Draco is that Harry has a super-bright Patronus whose form he keeps secret; he would be curious. So I don't think this quote is strong evidence that Lucius hasn't heard about the Patronus from Draco, since it is pretty likely that he would say something like this even if he has.

EDIT: Actually, since he believes Harry is Voldemort, he probably thinks the Patronus light he showed Draco was an illusion, and not useful for getting out of Azkaban at all. If he thinks Harry is Voldemort he's unlikely, then, to pry for information about it in this way.

Also, Draco may be more inclined to separate his observations from the implications of his observations. He's a scientist now, don't you know.

That may provide Lucius with superior intelligence, relative to what he would otherwise have obtained from a child raised by a doting Darth Vader.

I expect the amount of time he had was not sufficient for a full report on everything Draco knows of Harry. Perhaps the Patronuses didn't come up? Seems an odd omission, but not an impossible one.

Lucius didn't ask if Harry could cast a Patronus, I could buy that. But Draco's Patronus didn't come up? Harry's vow of vengeance against Narcissa's killer didn't come up? That whole thing was possibly the single most important interaction Draco and Harry have had, next to when Harry tricked Draco into sacrificing his belief in blood purity.

Comment author: Rejoyce 28 March 2012 05:10:29AM 2 points [-]

I thought Draco promised Harry that Draco wouldn't tell Lucius about their interactions. Several times.

Comment author: pedanterrific 28 March 2012 05:11:47AM 7 points [-]

I wasn't aware that Draco was an Occlumens. (If he can't beat Veritaserum, those promises mean precisely nothing.)

Comment author: Rejoyce 28 March 2012 05:22:50AM 12 points [-]

Draco's a manipulative little snake. Lucius never probably never asked, "Son, are you able to cast the Patronus Charm?" because he was probably under the impression that Slytherins weren't able to cast Patronuses so why bother asking. Hence, the topic never came up. Draco's a scientist now, he doesn't completely believe everything that Lucius says anymore. Draco's probably avoiding talking about dangerous subjects with his father. And of course, he could always lie.

Comment author: Alsadius 28 March 2012 06:37:38AM *  8 points [-]

Actually, he couldn't lie - he was interrogated under Veritaserum. That doesn't mean that the topic came up, of course.

If regular courts had veritaserum, I imagine the first question they'd ask would be "What are the things you don't want to tell us?".

Comment author: GeeJo 28 March 2012 07:20:50PM *  6 points [-]

But that is such a vague question. I could go on for hours about entirely irrelevant observations I wouldn't want to get out in public - how I feel about people at work, how much I enjoy certain bodily functions, sexual kinks. Nothing I'd want to tell them, but stuff I would objectively prefer for them to know than that I'd committed a heinous murder.

Comment author: ajuc 28 March 2012 07:33:52PM 6 points [-]

Yeah, phrasing it right wouldn't be trivial, but much easier than making wishes for UFAI, because Veritaserum is the equivalent of perfect box for AI, and Draco is human, so most of the definitions and assumptions he shares with the judges.

So maybe: "Tell me the things, you think I would want to know about, according to the best model of me you can construct."

Was Draco under Veritaserum when he spoke privately with Lucius, or only when he was interrogated by the Aurors ? We don't know how long Veritaserum lasts, nor how much time elapsed between the two.

Nevertheless, I believe it was two drops used, not three - so Draco didn't have to volunteer information.

Comment author: loserthree 28 March 2012 04:05:11PM 1 point [-]

It doesn't have to be about Draco's status as a scientist. We know from the text that he is very afraid of disappointing his father. That could be enough to keep him quiet until he's asked about anything it might possibly pertain to. Then he's forced by the drops.

Comment author: buybuydandavis 28 March 2012 06:54:06AM 2 points [-]

Yeah, Draco has been missing for a while. EY moved through this very fast. There's been a murder attempt on Draco, and a trial about it, and I don't remember seeing Draco since he was plotting to challenge Hermione.

Comment author: Blueberry 28 March 2012 11:04:27AM 4 points [-]

He's probably still healing.

My speculations were:

Maybe Lucius decided to let Draco keep some privacy.
Or he just hasn't gotten around to fully questioning him under veritaserum yet.
Or he's pretending that he doesn't know that Harry has a Patronus.
Or someone obliviated Draco of this information before Draco was returned to his father.
Or Draco is secretly an occlumens and he just pretended to let the veritaserum work on him.

I don't think Draco is an occlumens. I also don't think Lucius is such a nice dad that he would respect Draco's privacy after Draco was nearly killed.

I suppose he might not have had the chance yet, but if I was Lucius I would have tried really hard to get the chance to question Draco in detail before the trial. Unless Lucius was overconfident of his influence with the Wizengamot?

Comment author: loserthree 28 March 2012 04:02:18PM 6 points [-]

Draco knows that HJPEV claims to be able to Patronus. Draco knows that HJPEV presented himself as though he needed to hide his Patronus. Lucius knows that the 'light' side regards the ability to Patronus as a 'light' qualifier.

If Lucius also knows what Draco knows, then he would know that inviting HJPEV to Patronus would probably result in one of two things: either he learns something HJPEV may believe to be a valuable secret, or he casts doubt on HJPEV's 'light' side qualities.

it's win-win, just like you know he likes it.

Has Lucius not spoken to Draco in private yet?

Draco promised to keep Harry's secrets. Including everything that comes up in the Bayesian Conspiracy. Harry's and Draco's Patronuses are just additional items in that subset.

Comment author: loserthree 29 March 2012 04:32:03PM 2 points [-]

We are told that Occlumens can beat Veritaserum.

We are not told that promise-makers can beat Veritaserum.

Comment author: Logos01 29 March 2012 07:44:31PM 0 points [-]

Correct, but to put one under Veritaserum requires that you have sufficient information as to ask the question. And I don't believe that Veritaserum is described as forcing the volunteering of information which has not been requested of the subject.

Comment author: pedanterrific 29 March 2012 07:49:45PM 0 points [-]

"What do you know about Potter that he wishes to keep secret?"

Comment author: Logos01 30 March 2012 03:54:06AM 2 points [-]

Honestly, that doesn't map very well to my model of MoR!Lucius.

It would be an admission of defeat in terms of manipulation; and it would also disrupt his plans/designs to create a worthy successor in Draco.
