Now before I start... I am a firm believer that Dumledore IS dead. And as much as I hate to admit it, I do believe that Snape really is a good guy. However, I recently reread the books, things other people have written and surfed the internet to come up with some theories of my own that are quite convincing as to the thought that Dumbledore faked his own death.
We all know Dumbledore is not afraid of death. Is that because Dumbledore has a Horcrux? They say a Horcrux is evil but isn't it the killing of another person that is the wicked part? You don't have to make a Horcrux after you've killed someone. Was Dumbledore just being opportunistic after he defeated Grindelwald?
What about Hagrid? Does Hagrid know that Dumbledore has a Horcrux? Could he be the Secret Keeper of Dumbledore's Horcrux? Dumbledore himself said to McGonagall in Philosopher's Stone "I would trust Hagrid with my life." Has he by making Hagrid Secret Keeper?
What could be Dumbledore's Horcrux, if indeed he has one? I believe it could be Fawkes. What better to guard Dumbledore's soul than a creature that can never die?
Right so these are the clues that I got as to why Dumbledore faked his death:
(1) Dumbledore froze Harry. Why? He was under the Invisibility Cloak and in no immediate danger. Did Dumbledore need Harry as a witness to tell the Order that he was dead?
(2) There is missing text in the UK version of the book that found it's way into the US edition. Here it is:
"He cannot kill you if you are already dead... Nobody would be surprised that you had died in your attempt to kill me - forgive me, but Lord Voldemort probably expects it. Nor would the Death Eaters be surprised that we had captured and killed your mother - it is what they would do themselves, after all." - Chap. 27 p.553 UK edition
Why would JKR leave this vital piece of information out? Was she tempting us? If Dumbledore is keen to fake Draco and Narcissa's death, does that mean he is already planning his own?
(3) Why doesn't Fawkes attempt to save Dumbledore? Fawkes has already proved his loyalty and value by saving Harry in CoS and even Dumbledore himself in OotP. We know he was close by when Dumbledore was struck as soon after, his sings his lament. Why not try to save his master?
(4) Since when did Avada Kedavra make the victim "fly violently up and away from the Tower" and be suspended in the air? When Snape performs the curse, Dumbledore is thrown backwards. However, we already know these are not the effects the spell produces. When Cedric dies, he just drops to the ground. Also, when Frank Bryce dies, he just crumples to the floor. So what spell do we know that prduces those effects? Simple. Expelliarmus. In CoS, Lockhart is thrown back and in PoA, Snape is thrown back. Is it possible that Snape made a non-verbal Expelliarmus and simply said Avada Kedavra?
(5) If, like me, you believe Snape is a good guy, can it be safe to assume that he never meant to kill Dumbledore at all? Didn't Moody tell us in the very first DADA lesson he taught Harry:
"Avada Kedavra's a curse that needs a powerful bit of magic behind it -- you could all get your wands out now and point them at me and say the words, and I doubt I'd get so much as a nosebleed."
So even if he did say Avada Kedavra and didn't mean it, is it possible he didn't kill Dumbledore, only injured him?
(6) Fawkes Lament. We all know about the healing properties of a phoenix, particularly in CoS when Fawkes heals Harry, so is it possible that when Fawkes is lamenting, he is using his song to heal Dumbledore from the effects of the non-verbal Expelliarmus or half hearted Avada Kedavra?
(7) What happened to Dumbledore's wand? Afetr losing it when Draco disarms him, we never hear of it again. And thanks to Hagrid and Slughorn's song about Odo, we know that a wizard's wand is snapped in two when he/she dies. As far as we know, Dumbledore's wand hasn't been snapped. Is it possible Dumbledore's wand is missing because he still has it, still needs it because he is still alive?
(8) The last time we see Dumbledore's body is when Harry rearranges Dumbledore's glasses shortly after his fall. At the funeral, Hagrid brings in what is supposed to be Dumbledore's body. However it is covered and we don't know for sure is really is him.
(9) At the funeral, Dumbledre's body bursts into flames. No one starts this fire and since when do bodies burst into flame on their own? Sound like anyone we know? Fawkes has burst into flame several times over the course of the books now and as if we need reminding of this, Harry thinks he sees "a phoenix fly joyfully into the blue."
And there you have it. Those are the theories/clues as to why Dumbledore could possibly still be alive having faked his own death. Write what you think...
