Yeah! I'm with you all . But there is a question. Why Malfoy gave the diary to Ginny ?? Why he didn't gave it to any one else?? was it only a conicidance or some thing else??

Well the Malfoys ARE Death Eaters and the leader of the Death Eaters is Lord voldemort ie. Tom Riddle so the Malfoys must of been talking about their plan and Dobby heard it. It hints Lucius had somethign to do with it at the end when he storms out of the castle.

Yes they gave Ginny the diary to help Voldemort/Tom Riddle because well they are death eaters. they must have been talking about it so Dobt would have over heard.

we know why sorry but Dobby worked for the Malfoys Lucius gave ginny ythre boob therefore he knew what was going to happen

i agree too he probably overheard

I was exactly going to say this.

as we know from the 6th book that Tom Riddles diary was a Horcrux, but Lucius didnt know this. All Lucius knew was that there was enchantments on the book that will reopen the Chamber of Secrets because Lord Voldemort told him so, he also told him to keep hold of the book until he gave the order to do otherwise with it.
but since Lucius thought Voldemort was dead he thought he could use the book to get DD chucked out of the school, discredit the Wesley family and unleash the Battalisk on the mudbloods.
knowing the knowledge of this for as long as he did Lucius must of talked about the book and Dobby overheard, and then later on he overheard the plans for the book and the Wesleys and ran off to warn Harry.

hows that sound?

Yeah this was definitley something orchestrated by Lucius. So Dobby probably overheard them talking about it.

i don't think he heard anything about it in the beginning when he warned harry in his bedroom at 4 privet drive. i think i was just some of the magic house elfs have that allowed him to know something was up. but then during the year and after the first attack on mrs.norris i think he started to hear more from the malfoys and thats why he tryed to tell harry more but couldn't because of the laws of being a house elf.

My question on this entire situation: why give the diary away in the first place? I know it was to have the dark lord come back and kill all the muggle-borns in Hogwarts, but why now? From the Malfoy's viewpoint, Voldemort was dead, why risk your reputation or, worst-case scenario, life for someone you belive is dead or gone forever. That made no sense to me.

i finally understood y lucis put that diary in ginnys coldrun he wasd a death eater i found it out by watchin the movie i finally understood everything.

Well, obviously Dobby knew. Lucius Malfoy gave Ginny the diary, and he must have told Narcissa about it soon afterwards, and Dobby must have overheard their conversation and gone to warn Harry about it. Simple.

consider this; dobby regards harry as one of the key people who made elves right errr..; somewhat "OK" lucius who knows the elves loyalty rest with the malfoy's carelessly opened up stuffs with dobby hearing it and of course dobby having high praises to harry just told harry and did everything for harry. all in all it was summed up by dropping tom riddle's diary in ginny's.

I think he knew becasue Mr. Malfoy slipped Tom riddles diary into Ginny's cauldron at diagon alley and then he couldve said somethig about the plan to his family and Dobby could have overheard.

So does Lucious know Voldermort is the heir to slytherin then? Did he know the chamber would be open and the person to open the chamber would be the heir to slytherin? That is what I have always wondered. Also Dobby knows terrible things will happen if Harry goes back but what things petrification, death, the COS opening?

I must agree with shinra.corp.
Lucius didn't know that the diary was a horcrux. And I don't think that Voldie wanted that diary in Hogwarts. Not so early, before he got his body again.
Why bother keeping your horcruxes well hidden, if your Death Eaters are going to be handing them away? I think Lucius was just trying to discredit Weasley. He might have had a guess that the diary had something to do with the Chamber of Secrets ( killing a lot of Mudbloods - is there a better way of showing Voldie that he still supports him). But he was taking a long-shot with all this, I mean Ginny could've thrown away the diary, or she could've left it at home. Lucius knew this, and no way he would've been taking this chance if had the slightest idea just how important the diary was.
I think Voldie was really raving mad at him.

I agree. Lucius did not know it was a horcrux or of that much importantence to the Dark Lord. He also doubted that the Dark Lord woud return.

Lucius got nervous will the MoM crack down of Dark Arts objects. He did not want the diary in his possesion because he knew it contained dark magic. He needed to get ride of it so he wouldn't get into touble.

I believe he inteneted to take the book to Borgin and Burkes, where he had placed other of his Dark items for safe keeping. However, after the altercation at Flourish & Botts with Mr. Weasley he decided to slip the book into Ginny's basket as revenge. After all how would it look for Aurthor Weasley's family if Dark Arts objects were found in there possesion? Very bad for Mr. Weasly. Perhaps Lucius wanted Mr. Weasley to loose his job.

Lucius mis-judgement of the situation caused big trouble for him instead. That was the first strike against him for the Dark Lord.

This is my opinion

If Lucius had just wanted the diary to get to Hogwarts he would have given it to Draco. I think he was informed about the chamber and that it could only be opened by an heir of Slytherin. Keeping in mind that the chamber was opened by Ginny, does this mean she is an heir, or just easily influenced? The Weasleys, being pure bloods, could very well be related to Slytherin. They have been labeled as blood traitors. I think this is just a twist of fate. The timing of the opening of the chamber is premature to the return of LV. His return was not confirmed for another two years. I think Lucius was just getting scared that he had this kind of connection to LV and that he would soon be investigated. He was just trying to get rid of the diary.

See my post dated 11/20/06.

I firmly do not believe Malfoy knew what the dairy could do. I believe Voldemort asked Malfoy to hold onto it for safe keeping. I think the plan against Harry involved something else NOT having to do with the dairy. The dairy being placed in Ginny's basket was an implusive move.

It may have been meant for Harry but I don't believe Malfoy knew it would open the chamber. I wanted Harry to get into trouble for having a Dark object at Hogwarts.

Dumbledore told Harry Voldemort trusts no one and even though he appears to have close "friends" they are truly his servants. He will kill a Death Eater as quickly as any enemy.

Dobby shows great bravery ... who risked everything by trying to warn Harry of the plot against him. Dobby made some big brave choice to prevent Harry from returning to Hogwarts (i.e. stopping his letters, coming to visit him to tell a wizard what to do and sealing the passage to platform 9 3/4). because he identifies with the good side. Or does he?

This goes against all of the house elf rules... Dobby also knows a lot about Harry and possibly his importance to the wizarding world. Dobby tells Harry, "He is too great, too good to loose." Does Dobby know that Harry is needed to defeat Voldemort?

What was the plot against Harry? I know I'm jumping ahead but I don't think we ever find out. I know Luscious Malfoy was cooking up a plot on his own but why, if the orders were not from Voldemort?

We also see that house-elves have their own powerful magic. Later we learn hose elves can not use their magic without their master's permission. Among other things, this magic allows house-elves to instantly travel places, in a manner similar to apparition, but the house-elves are able to do this within Hogwarts, even though normal apparition is impossible there.

At the end of CoS, Harry tricks Lucius Malfoy into freeing his house-elf, Dobby. Most house-elves would be offended if given clothes, for it would mean that they had failed to properly serve their masters, but Dobby enjoyed being set free.

Was Dobby the one with the plot so he could be freed from the Malfoys???

I don't think Dobby's visit to Harry had anything to do with the diary. It had to be some other plot. How did Dobby know where to find Harry? Do elves have location powers like owls? He had to be told where to find him. It's possible that he overheard a scheme to hurt Harry and rushed to inform him, but where did he get his loyality to Harry. I think it's more likely that he was sent by one of the Malfoys in an effort to stop Harrys return to Hogwarts.
