Who put Rosmerta under the Imperius Curse?

I would go with this theory because I see no reason why Draco could not have cast such a spell. I mean he would really want the plan to work due to the circumstances and Rosmerta was part of that plan. In a way Draco on the quiet has always been powerful but just lacks the confindence to pull off what he is capable of because he is casting the wrong type of magic (magic that does not match his true feelings or emotion).

Ah... actually, Draco was on detention with McGonagall when the cursed necklace incident happened. Harry told McGonagall that he thought it was Draco and McGonagall told him that it was impossible as Draco was with her on detention.

However, if Draco had imperioed Rosmerta before the school year even started he could have been controlling her while on detention.

I think he had to have done it before the school year started if his main reason for doing so was to find out when Dumbledore was out of school. Which he needed to do to get the DEs in, and he was after all expecting to get the cabinet fixed fairly soon. The necklace incident wasn't till late October by which time he was starting to panic a bit.

I have full reason to believe that it was Mundungus. I mean in OOTP he was in The Hog's Head listening to what Harry said and all about the DA lessons and everything like that. And Sirius said that he got himself banned from The Hog's Head. This gives me reason to believe that Mundungus goes into a lot of taverns. So the possibility is very high that he did put Rosmerta under the Imperius Curse.

It was probably Bella or some other DE. THe DE's were helping Draco with his task.

[iamgranger]

I do think it was Draco who put Rosemerta under the Imperius. Just because he was in detention with McGonnagall that day doesn't mean he didn't have other opportunities before or during the school year. Even though he doesn't have the marauder's map, he might have been able to sneak out at night or something.

But what about Dumbledore's trust in him?
Also in OOTP, he was keeping watch over Harry, probably on Dumbledore's orders. I don't think the reason that he probably goes into a lot of bars in solid enough to assume that he cursed Rosmerta. Hagrid goes into both Hogmeade bars and nobody suspects him.
Just because we see Mundungus in Hogmeade the day Katie was given the necklace isn't reason enough either, I believe. I can't think of any canon that suggests that Mundungus is anything more than a petty thief who is useful to the Order.
On the other hand, we have plenty of canon that tells us Draco was desperate enough to do anything to complete his mission. We also have Draco ready to use the Cruio curse on Harry in HBP. I believe he was ready, willing and able to curse Rosmerta and if anyone helped him it would have been Bella or Narcissa.

I don't think that it was mundungus. I mean, in the 5th book he was put there by Dumbledore with Mrs. Figg (i think that was her name) to protect Harry. I personally think it was Draco or a Death Eater.

If anyone helped Draco with the necklace plan, I think it must have been Zabini as he was definitely in the 3 Broomsticks. Nott might have been but wasn't mentioned, and you'd have expected him to be with Zabini - there aren't that many Slytherins in their year for him to be hanging out with anyone else really. (Unless he enjoyed the scintillating conversational skills of Crabbe & Goyle?)

That wasn't my idea...it was Abhishek's idea...he had found the article, written on Theodore Nott, at Wikipedia interesting...moreover he had found the quote which mentioned that they were having a whisered conversation...when they were attending Slughorn's first class...when the supposed Polyjuice theft took place...

[sulihawk]

Zabini was in the Three Broomsticks when Katie Bell was imperoied, it could be that was a polyjuiced Draco. But either way, why would they imperio Rosmerta to imperio Katie? The simplest answer is he imperioed Katie on the way to the bathroom, it would have just looked as if they were having a conversation. Leanne just tells Prof. McGonnegal that Katie went to the bathroom and came back with the package. What is the greater mystery is that they didn't go to the bathroom together as girls tend to do.

[Abhishek_K]

Finally, someone else believes that it could be Mundungus just like me. I thought of him for the same reason you guys are thinking about Zabini, i.e. he was mentioned during the whole Katie incident + he had no business being there in the first place. I mean why didn't he run when he saw Hogwarts students in the area. He was selling Sirius's old stuff and the probabillity of meeting Harry is extrememly high isn't it ?

I think of Nott for the precise reason that Mysterious pointed out :

moreover he had found the quote which mentioned that they were having a whisered conversation...when they were attending Slughorn's first class...when the supposed Polyjuice theft took place..

Zabini could have been helpful too, I don'y disagree.

I'm still trying to find a decent quote or passage which can link up the imperiusing and anyone of these possible culprits.

[horcrux4]

But why would anyone (Draco or pals) go into the 3 Broomsticks on Hogsmeade visiting day and try to Imperius Rosmerta when the bar was full, to get her to Imperius someone else? Why not just Imperius a Hogwarts girl who was on her own at some point? The plan to send the necklace to Dumbledore was pretty stupid anyway as the person most likely to be affected by it would be Filch with his secrecy sensors! That can't have been the only reason Rosmerta was Imperiussed. Nor would Draco have had time on that day to set up the coin exchange with Rosmerta, which seemed to be crucial to his plan to get the DEs into Hogwarts. He had to have done it earlier, so she could report to him on Dumbledore's movements, using the coins.

And I think it's unfair to assume that because Mundungus frequents bars that he would Imperius someone. It is an Unforgiveable Curse after all, and although he'd risk brief imprisonment for petty theft, I don't think he'd risk life in Azkaban for Imperiussing someone. He's too self-centred.

The point of Jo's putting him in Hogsmeade that day is more likely to set up the idea that if he's been nicking Sirius' stuff, he might have the gold locket or have sold it to Aberforth. It needn't be anything to do with Rosmerta.

iamgranger- It was the first Hogsmead trip of the year, and Draco was in detention with Mcgonnagle. So if he did it, he had to have done it beforethat day. Plus he had to get the necklace to her, from B&B's, without bringing it into Hogwarts. He had to have control of her before school started.

[Layla]

Mundungus seems the least likely option to me. There's no reason why Draco could not have Imperiused Rosmerta earlier. Bellatrix could have done it.

Snape... I'm not so sure... he may have helped Draco in some way, but I don't think he actually did it.

[mmka]

My first thought is Draco. He certainly could have been coached in the technique while away from school.

...probably by Bellatrix while she was teaching him occlumency.

[Abhishek_K]

I doubt bella could have come to hogmeade being WANTED DEAD OR ALIVE and all, plus Draco getting out of hogswarts seems pretty unlikely and imperiusing rosmerta in front of so many guys is not a viable option so Dung is a good guess isn't it ?

I think you are right that Bella couldn't be seen in Hogsmeade and that Draco couldn't get out of Hogwarts, but that doesn't mean Draco couldn't have done it before he returned to school. Mundungus seems unlikely to know how to do the Unforgiveables, since they wouldn't be needed for the kind of petty theft he specialises in.

I have my doubts on any pre-hogwart visits to be honest . The Zabini theory seems far more likely than the pre-hogwarts visit. Seeing the way Jo rights i'd put my money or Mundungus or Zabini but how they did it in front of such a huge gathering is beyond me.

The main reason I think Draco did it before school started is that he set up the coins to communicate with Rosmerta and he wanted to know when Dumbledore was out of school. I think she was Imperiussed long before the necklace incident which was a last-minute panic measure of Draco's. It would have been very complex for someone else to set up the coins and I don't know that Mundungus or Blaise could have done it. Blaise certainly wouldn't have had the time or opportunity in the crowded pub on Hogsmeade visiting day to do all that had to b done.
