12 Grimmauld Place

In one of the last chapters of Harry Potter and Deathly Hallows, Voldemort "kills" Harry *JKR has said many times that you cannot come back from the dead, and since Harry did, he did not really die*. However, when Harry "dies" he sees a crying baby. The ghost of Dumbledore tells Harry that that baby is the piece of Voldemort that had latched itself onto Harry, which Voldemort had actually killed, so Harry was not dead. Then Harry and Dumbledore talk about pretty much everything that had been puzzling Harry--they discuss Voldemort and even Dumbledore. At the end of the chapter, Dumbledore gives Harry the choice to continue living, or to die. This is probably because Harry hadn't really died. Anyway, Harry chooses to live because with Harry, there is a chance that he can defeat Voldemort while he is mortal. The baby horcrux that was once inside Harry, that had been Voldemort, had no choice but to die. Harry said that where they were resembled Kings Cross station, in London. This is actually very symbolic, because it is like choosing to go on (the train) and die, or to leave the sort of purgatory he had been in. Harry had only half died, only gotten to purgatory, so he could choose to die or live. Dumbledore says that it had all been going on in Harry's head, but that it was still real as  Harry comes back to life. When Harry comes back to life,  he kills Voldemort, and he does not come back because was now mortal. Harry knows that he will not come back also because his scar hasn't hurt in nineteen years during the epilogue.
I believe the place that Harry had actually been was behind the veil.
My reason for thinking that Kings Cross is actually behind the veil is because Harry hears whispering in book 5 when he first sees the veil. If the whispering from the veil are souls, had they been completely alive, they would be talking. If they were dead there would be no sound, since we never directly hear from the dead, even if we get representations of them. Whispering is between talking and no sound, and purgatory is between life and death. Harry was in purgatory and the purgatory is behind the veil.
I also have more evidence. I think that Harry did not go "Beyond the Veil" like Sirius, I believe that he went behind it.
I think that there are two sections to the veil-one is purgatory, and that is closer to the real world. I believe that that space is very small because those who die may go through purgatory quickly and there doesn't need to be a lot of space. I think that the sort of train that the baby Voldemort horcrux went on would take him to the death part of the veil, beyond purgatory, where Harry probably was.
You're probably thinking about how Sirius went through the veil and died. Since he was hit with a jinx, I believe that he fell behind the veil, but his body was moving so fast because of the jinx and he sped right over purgatory and by the time his ghost landed, it was dead, past the point of purgatory.

A list of the stuff we had gotten right for Deathly Hallows contains spoilers

(Highlight to see properly)

Ideas we had gotten right:

-R.A.B. is Regulas Arcturus Black
-Snape is good
-Snape loved Lily
-Harry is the seventh horcrux
-Harry will live


Ideas we had partially gotten right (see original theories for these)

-Ollivander
-Slytherin's locket, Snape and R.A.B.
-In memory of F. and G.

    Below are theories (a.k.a. predictions) which were written from before the last HP book, Harry Potter and the Deathly Hallows, came out.
If you have not read the newest and last installment of the series, it may be a good idea to read these theories soon before reading the book, so you have the ideas in your head...

    When Snape was at Hogwarts, he was an unpopular boy. He was bullied by James Potter and other students saw it as entertainment. ("Several people watching him laughed; Snape was clearly unpopular." [OotP, pg.646]) As a kid, Snape didn’t have a very good childhood, as we see when Harry is in an Occlumency lesson. But there was one person who was sympathetic to him, who wouldn’t laugh at Snape, who stood up for Snape to James and Sirius. This person was Lily Evans- Harry’s mother. (“Leave him alone,” Lily repeated. She was looking at James with every sign of dislike. “What’s he done to you?” [OotP, pg. 647]) Although they probably weren’t really friends, Lily was the only person who would stand up for him when nobody else would. In “Snape’s Worst Memory” probably isn’t the only time where Lily is friendly towards Snape.
    Snape, like other Slytherins, loves all things Slytherin, but that does not mean that he wouldn’t like her because she’s Muggle-born, like other Slytherins probably would (for example, Draco and his father, Pansy Parkinson, Blaise Zabini and obviously Voldemort). We’ve seen another Slytherin who was not prejudiced against Muggle-borns…Horace Slughorn. He was one of Lily’s teachers, and he describes her as, “[One of my favorites]... Lily Evans. One of the brightest I ever taught. Vivacious, you know. Charming girl.” [HBP, pg.69-70] This shows that not all Slytherins hate Muggle-borns, so it’s very unlikely that Snape would hate Lily for being Muggle-born, especially being a half-blood himself. But that doesn’t say anything about him loving her.
    There isn’t much evidence of this idea, but there is one thing. People may think that Snape was protective enough of this memory to put it in his Pensieve because of the humiliation of having the school see his underwear. Lupin says that the spell, “Levicorpus”, the spell used to hoist you into the air by your ankle, was very popular at the time, so Snape, like everyone else, was a target to this spell, especially being unpopular and all. Now that Snape is a grown man, and a powerful wizard, the humiliation of having his underwear shown to the school probably isn’t his largest concern. It’s probably because of what he said to James when Lily stood up for Snape (“I don’t need help from filthy little Mudbloods like her!” [OotP, pg. 648]). He didn’t want Lily to see him so vunerable, so he took his anger out on her even though he didn’t mean those words. Doing this, he drove away Lily, the only person who had ever showed real kindness to him. In our lives, we often take our anger out on those we love most, and Snape took his anger out on Lily. Since this memory is one of the three memories in the Pensieve, why else would this memory be one of them if he didn’t care about Lily? So we are left with is this- Snape loved Lily, and he was ashamed when he drove her away with his cruel words.

This theory was inspired by the theory in “What Will Happen in Harry Potter Book 7?” By Mugglenet.

        Draco Malfoy has always been considered a bully to Harry and his friends throughout most of the series. He seems to have been a spitting image of his father, Lucius Malfoy. Lucius Malfoy is one of Voldemort's Death Eaters. When we first meet Draco in book 1, he says that he hopes to be in Slytherin, because his entire family has been in Slytherin. When he and Harry are talking, Draco says that the muggle-borns shouldn't go to Hogwarts, because they weren't from old wizarding families that practiced magic. He also says to Ron, "Think my name’s funny, do you? No need to ask who you are. My father told me all the Weasleys have red hair, freckles, and more children than they can afford."(pg. 77, SS) Draco is eleven when he says these things. Does this sound more like Draco or his father talking? I think it sounds more like his father, and Draco, hearing it a lot, picked it up, not really understanding what it meant, but using it anyway to sound cool. At age 11 and having never been to Hogwarts, what are the chances he's ever even met a muggle-born? In books 2-5, we constantly hear Draco talking about his father "Father says this, Father says that..." Also, his father has trained him in a way to respect dark and powerful wizards, like Lord Voldemort. It seems that Draco is the object under his father's influence- if you will, his father's victim. 
        The Malfoy family has always come across as a nasty family, but they're not really considered a threat until Harry sees Lucius Malfoy in the graveyard, one of Voldemort's Death Eaters, in Goblet of Fire. This only supports Harry's theory that the entire Malfoy family is evil. By this point, Draco is fourteen, and now that he's getting older, he is starting to truly believe what his father is telling him. He's now getting too far in under his father's influence. Draco's idea of a great honor is serving Voldemort. This is all the influence from his father that he'll ever need. When the D.A. and Harry fight Voldemort and a few of his Death Eaters in the Department of Mysteries, Lucius is sent to Azkaban. Draco is now without a mentor, so he turns to Severus Snape, who has "always been Draco's favorite teacher." (pg. 33, HBP)             The relationship between Draco and Snape has also been a relationship similar to Harry and Dumbledore's. When Narcissa Malfoy, his mom, realized her son's life was in danger, she turned to Snape to protect her son. At age 16 Voldemort has found Draco to perform the task of killing Dumbledore. Voldemort probably knew that he had no chance against Dumbledore, but he has been recruited to pay for his dad's failure and being sent to Azkaban. Draco doesn't care and couldn't feel more honored as we hear him tell his friends in the beginning of HBP on the Hogwarts Express. He thinks it's the chance to prove himself to the Dark Lord. Is it really? Soon Draco is overwhelmed by the task and starts to crack under the pressure. (Draco Malfoy was standing with his back to the door, his hands clutching either side of the sink, his white-blond head bowed. "Don’t," crooned Moaning Myrtle’s voice from one of the cubicles. "Don’t...tell me what’s wrong...I can help you..."
    Draco is really scared, and we can sympothize him. Dumbledore is a more powerful wizard than Voldemort, and even Voldemort, feared by so many, fears this man. Draco is caught between two ropes- Dumbledore may possibly harm Draco for the attempt to kill him, but Voldemort will probably kill him if Draco doesn't kill Dumbledore. So then who's Draco's bigger fear- Dumbledore or Voldemort?
    We have watched Draco grow more and more mean throughout the books. His father has turned him into a Dark Arts lover and we've watched how Snape has encouraged Malfoy bully Harry and his friends. We've also seen him complain about Dumbledore for the past six books. The lack of respect for Dumbledore, however, is another thing acquired from his father. He's just like any other bully- a follower and a coward because he's willing to go along with what the people around him see to be good.
    Perhaps Draco actually feels safe at Hogwarts, with Dumbledore. It makes sense because whether or not Draco was brought up to be a supporter of Dumbledore, he was brought up by another coward. No matter how braggy and intimidating Lucius ever was to his son, Draco only fears Voldemort as much, maybe more, than everyone else does. Even though Draco had immense respect for Voldemort and was constantly dissing Dumbledore, he knew that Hogwarts was his sanctuary. At Hogwarts, the only thing he ever really had to worry about was no more than being a kid. When Draco confronts weakened Dumbledore on top of the Astronomy tower in HBP, Dumbledore notes that perhaps Draco was not cut out to be a killer. ("You have been trying with increasing desperation, to kill me all year. Forgive me Draco, but they have been feeble attempts...So feeble, to be honest, that I wonder whether your heart has been really in it."-pg. 585, HBP)
    Draco explains how he had set up the cursed necklace, the poisoned mead, and the pair of vanishing cabinets for entrances of Death Eaters into Hogwarts.  Dumbledore praises him for his cleverness and then Malfoy “bizarrely seemed to draw courage and comfort from Dumbledore’s praise,” (pg. 587, HBP). Draco was happy to recieve praise because it distracted him from the task that he was assigned to do. Dumbledore offers a plan to hide him from his parents, Death Eaters and Voldemort. Draco seems interested, but he changes his mind when he hears the Death Eaters running to his aid. ("But I got this far, didn’t I?" he said slowly. "They thought I’d die in the attempt, but I’m here...and you’re in my power...I’m the one with the wand...you’re at my mercy.""No Draco," said Dumbledore quietly. "It is my mercy, and not yours that matters now."Malfoy did not speak. His mouth was open, his wand hand still trembling. Harry thought he saw it drop by a fraction.-pg. 592, HBP All the Death Eaters want him to kill Dumbledore, do it quickly and get it over and done with, but Draco just stands there. Eventually Snape takes charge and does the killing for him. At this point, the fate of Draco depends on the fate of Snape. Because Draco had refused to kill Dumbledore, Voldemort is going to be extremely angry at Draco. He will probably be killed because of his failure. Sadly, he can't really redeem himself because he's so far off from either side.

Since Ollivander was evil, he has an important role. Maybe, for some reason or the other, he turned good. And what if he has something special guarding him in his shop? That would make him safe from Voldemort.

To the Dark Lord,

I know I will be dead long before you read this

but I want you to know that it was I who discovered your secret.

I have stolen the real horcrux and intend to destroy it as soon as I can.

I face death in the hope that when you meet your match,

you will be mortal once more.

R.A.B.        -Half Blood Prince, p. 609

Fans who have investigated in the category of whom R.A.B. might be have come to the conclusion that R.A.B. was probably Regulas Black- the "A" being his middle name. Regulas was Sirius' younger brother. Sirius hated his brother. Sirius said to Harry that Regulas, like his parents, had been involved with all the pure-blood mania in OotP. As briefly mentioned, Regulas was a young Death Eater, and was killed "by Voldemort, or on his orders" when he was about eighteen. We know that he only lived a few days after deserting the Death Eaters as well. But then, why was he killed? How would R.A.B. have known about the horcruxes if Voldemort intended to keep the horcruxes a secret?

     Remember the cave, where the decoy locket of Slytherin's lay, that held R.A.B.'s note in it? The boat that took Dumbledore and Harry across that lake to get to the cave? That boat was only supposed to hold one wizard, meaning one of age (seventeen or older). Harry was sixteen when he crossed with Dumbledore, so only Dumbledore counted. If Regulas was in Voldemort's inner circle, he could have known about the diary, which went into the hands of Lucius around the time of Regulas's death. The locket probably had been in that cave for a really long time, seeing the memory in the Pensive in HBP.

     Let's talk about Snape for a moment. There's a pretty popular theory going around that Snape was in love with Lily Evans (later Lily Potter- Harry's mom) because she was a charming girl, and was the only person who ever seemed to give Snape genuine kindness. James Potter, Harry's dad, saved Snape's life when they were still in school, so Snape owed James a life debt. When Snape reported the portion of the prophecy that he heard to Voldemort, Snape realized that he had caused the deaths of James and Lily- never being able to repay that life debt, and helping the death of the only woman he had ever loved. Depressing. Naturally, Snape feels guilty.

     Assuming that Regulas and Snape were in Voldemort's inner circle around the same time, there's a small chance that Regulas found out about the horcruxes, but through investigation, and then told Snape- Voldemort's still not going to go around telling his "friends" that he is creating horcruxes. Regulas would have had a change of heart, and wanted to stop Voldemort- but not directly. Only to make the right person (who would be Harry) easier to kill Voldemort by destroying Voldemort's immortality. But since Voldemort did not suspect that Regulas knew about the horcruxes, Voldemort still might have asked Regulas and Snape to hide the locket in the cave. It might have been days before Regulas turned seventeen, but he still qualified as an underage wizard. Snape would qualify to cross the lake with Regulas. Then when they got across, Regulas and Snape could have replaced the locket with it's decoy, and the note written inside of it would have already been pre-written. They both would have wanted to stop Voldemort. A Death Eater could have found them coming back, and killed Regulas a few days after his seventeenth birthday, since he only managed to live a few days after deserting the Death Eaters. The Death Eaters might have thought Regulas was older- so they thought he turned eighteen when he actually turned seventeen.

     In any case, what would be the whereabouts of Slytherin's locket?

In book 5, Order of the Pheonix, Harry and the Weasleys go through items in 12 Grimmauld Place. They found a locket, large and concealed, none of them could open it. This locket that we vaugely see is probably the very locket of Salazar Slytherin, the very horcrux which is missing at the end of HBP (Regulas probably hid it in 12 Grimmauld Place).

On the other hand, while it still was probably hiding in 12 Grimmauld Place, Mundungous Fletcher was caught by Harry stealing Sirius's stuff after Sirius died. He might have taken this locket, and sold it without realizing it's intense value. This makes it a lot harder for Harry to track down, but it's still possible for Book 7.

     We'll just have to wait and see what will happen in Deathly Hallows!

I found this on www.mugglenet.com... it's a different theory to how Voldemort will die in the end. I think this is a convincing arguement, and worth considering. (Abridged from original text)
"
How will Harry defeat Voldemort without becoming a murderer? Harry will have to vanquish Voldemort in one way or another, but I think he will not be using Avada Kedavra to do this.

As Dumbledore explains, Harry has the ability “the Dark Lord knows not” -- that is, the ability to love. If Harry were to use the Killing Curse, which requires pure hatred, this is forgetting his advantage.

Love has already saved his life three times (at Godric’s Hollow, while facing Quirrell, and in the Department of Mysteries) and it will likely come into play once more. For Harry to push this love from within in an effort to murder is an unwise decision.

Harry’s heart will prevent him from performing the Killing Curse, “the supreme act of evil.” Harry is pure of heart, as he has always been and will remain so. Harry may choose not to murder, feeling this is not morally right.

He has a choice in how to destroy Voldemort and I don’t think this is how we will do this. I can’t imagine Harry lowering himself to Voldemort’s rank, to the point where one is cruel enough to take another’s life.

If Harry chose murder, it would split his soul. If Harry murdered Voldemort, this means his “whole and untarnished” soul would be no more, as Slughorn tells a young Tom Riddle that killing rips the soul apart.

Harry definitely wants Voldemort vanquished, but he may come to a point at which he realizes he does not want to kill Voldemort, but destroy him through other means. He may search for a different approach.

I personally wouldn’t want Harry to lower himself to the point where he would kill another, not even one as evil as Voldemort. I do not want Harry to be a murderer! If Harry committed murder, it would not be a happy ending. There must be other ways. If not by Avada Kedavra, how will Harry kill Voldemort?

As Dumbledore’s Chocolate Frog wizard card states in Sorcerer’s Stone, Dumbledore “defeated” Grindelwald in 1945. How exactly did he “defeat” Grindelwald? There’s no indication that he murdered this Dark wizard.

Is there a spell that can defeat a person without killing? Actually, there is a mysterious spell mentioned in Order of the Phoenix:

Dumbledore flicked his own wand. The force of the spell that emanated from it was such that Harry, though shielded by his stone guard, felt his hair stand on end as it passed, and this time Voldemort was forced to conjure a shining silver shield out of thin air to deflect it. The spell, whatever it was, caused no visible damage to the shield, though a deep, gonglike note reverberated from it, an oddly chilling sound...
“You do not seek to kill me, Dumbledore?” called Voldemort, his scarlet eyes narrowed over the top of the shield. “Above such brutality, are you?”
“We both know that there are other ways of destroying a man, Tom,” Dumbledore said calmly.
(pp. 813-814, OotP, American hardcover edition)

This is what we know: There is a spell that destroys a person without killing. It seems there is no way of deflecting it (much like Avada Kedavra) without a magical shield of some sort. Yet it left no physical damage.

We know to cast an Unforgivable Curse, one needs to concentrate their hatred. Maybe this spell is similar, in that one must concentrate their love to cast it. As love is the one power Harry has that Voldemort does not, I think that using love as a force in this way against Voldemort is a plausible idea.

Harry has to discover how to use this spell on his own. I’m sure he is not going to find the spell to this one in a textbook. We know Dumbledore and Voldemort are both familiar with this spell, so reviewing Dumbledore’s battle with Grindelwald will be of help, especially if this is the same spell. I’m pretty sure it is. "

In book 6, even though Draco Malfoy was supposed to kill Dumbledore, he couldn't. We don't know his reasons or emotions, but we know he couldn't. Voldemort knows this, and he's probably annoyed that Snape had to blow his cover having to do Malfoy's work for him. Voldemort, not being the friendliest person in the world, being the vicious wizard he really is, could have killed him for it. This would also be pretty smart thinking, because it could possibly drag Harry there. Now I know that Harry and Draco despise each other, but Harry might want to see what happened, and Harry would be the bait. Now Harry's not stupid. He's not the kind of person who would just go to [wherever Draco's killed] and casually run into Voldemort. Chances are, one of the Death Eaters would kill him first before he even saw Voldemort if he went alone. So maybe Harry would go with some of the members of the Order of the Pheonix, and while they are holding off some of the Death Eaters, Harry could fight Voldemort. To see what I think would happen next, see the theory below [the Prophecy- and the veil].

By the way, Draco Malfoy means "bad faith" in latin.

According to the prophecy we hear from Trewlany in B5, "none can live while the other survives". So either Harry or Voldemort has to kill each other in the end. Now we know how in B4, Harry's and Voldemort's wands connected because the wands were brothers. So if brother wands can't hurt their owners, then they can't kill each other using their wands. I also highly doubt that one of them would strangle the other one to death, and there probably wouldn't be enough time to get someone else's wand and use theirs.

          Let's think then... picture Harry and Voldemort battling their final battle, and their wands can't hurt each other. What else can we think of that's not using a wand that's still magic? Here's a hint- "Beyond the veil". If Harry can pull Voldemort through the veil with him, then it will be futfilling the prophecy. None would be living, because clearly, both would be dead. This also makes sense because that way, it would be very hard to continue the books, and J.K.R. says frequently that she does not want anyone to continue the series after her.

Although Dumbledore trusts Mundungous Fletcher, Molly Weasley disagrees. In book 5, Alastor "Mad-Eye" Moody showed Harry a picture of the Order before Harry's 1st encounter with LV. Fletcher was not in this picture.

Are we sure that we can trust Fletcher then?

What if the reason that Fletcher was not in that picture was because he was a Death Eater (DE)? I know that some people may get a good vibe about him, but he was stealing Sirius' stuff. Maybe he took the locket. Then Harry would have to track him down and find it.

 

As many of us know, Fabian and Gideon  Prewett were Molly Prewett Weaselys’s brothers, as it says on page 174 of OotP. They worked for the Order of the Phoenix, and they were murdered by You-Know-Who’s followers. 

As Ron once said to Harry, his mother didn’t like to talk about her side of the family much, and she didn’t like to talk about her brothers as well.

Suppose Molly’s twin sons, Fred and George Weasely were named for their uncles. As we can tell, in book 5, the twins seemed to really take an interest in the kinds of things that were related to the order, and the order itself. Likely, they would do anything to stop You-Know-Who and his death eaters.

What if Fred and George end up fighting for the order? What if they end up having the same, sad fate as Fabian and Gideon?

Also: Fabian means "Great Warrior".
