In September of 1927, the Defence Against the Dark Arts professor Albus Dumbledore looked into the mirror and saw his former best friend, Gellert Grindelwald, indicating he still has lingering feelings for him, as well an old memory of himself and Grindelwald in a barn where they made a blood pact; swearing an oath ...
But what does his response to the mysterious Mirror of Erised tell us about what's to come? Thick woollen socks. That's what Dumbledore tells Harry he sees in the Mirror of Erised during their first ever face-to-face conversation in Philosopher's Stone.
What he actually saw was his family together again- Ariana alive and well (she was ill and died during the duel between himself, his brother and Gellert Grindelwald), Kendra and Percival, his parents, alive again (Kendra died and Percival died in Azkaban), and his brother Aberforth, having made peace with him.
In 1998, while telling Aberforth Dumbledore about what happened when his brother drank the potion, Harry mentions that he believed that Dumbledore was reliving the 3-way duel that broke out amongst them and Grindelwald that resulted in their sister, Ariana's death.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
Albus Dumbledore left Ron the Deluminator in his will, but besides it being useful for taking the light from a place, it was unclear exactly why he had bequeathed it to Ron… until he did something devastating. He abandoned Harry and Hermione on their hunt for Horcruxes.
Ariana was the youngest of three children of Percival and Kendra Dumbledore, born in 1885 in Mould-on-the-Wold, a wizarding village in England. At the age of six, she was seen practicing magic by a group of Muggle boys. When she was unable to show them how to do the same thing again, they violently assaulted her.
Voldemort, whose face has slowly regrown on the back of Quirrell's head, is revealed to be the professor's secret master. Harry is forced to stand before the Mirror of Erised. It recognises Harry's lack of greed for the stone and deposits it into his pocket.
We return to Hogwarts
We then move back in time as the younger Dumbledore (Jude Law) holds the blood pact necklace with the chain wrapped around his wrist.
In 1992, the Mirror was the final guardian of the Philosopher's Stone in its Chambers. Dumbledore placed an enchantment on the mirror, hiding the stone inside of it, and allowing the mirror to transfer the stone only to one who wanted to find the stone but not to use it.
Dumbledore and Grindelwald only spent about two months together, but the two canonically became lovers in that time. Their relationship was passionate and intense, and each wizard helped shape the philosophies of the other.
The Emerald Potion, also known as the Drink of Despair, is a mysterious potion which induces fear, delirium, and extreme thirst. According to Dumbledore, the potion cannot be penetrated by hand, vanished, parted, scooped up, siphoned away, transfigured, charmed, or otherwise made to change its nature in any way.
Snape is first revealed to be a skilled Legilimens — a witch or wizard with the ability to read another person's mind — when Dumbledore arranges for Harry to practice Occlumency — the art of shielding one's mind from invasion — with the potions professor in Order of the Phoenix.
The big “secret” about the Dumbeldore family that the title promises is actually an explanation of the last film's cliffhanger. Albus confirms to Creedence early on in the film that he is in fact a Dumbledore, quashing any rumor that Grindelwald had lied to the young boy in order to sway him to his movement.
Percival Dumbledore (fl. 1881) was a wizard, the husband of Kendra Dumbledore and the father of Albus, Aberforth, and Ariana Dumbledore. After attacking three male Muggles who assaulted Ariana, he was sentenced to Azkaban. Percival died there sometime later after 1890.
The Tales of Beedle the Bard first appeared as a fictional book in J. K. Rowling's Harry Potter and the Deathly Hallows (2007), the seventh and final novel of the Harry Potter series. The book is bequeathed to Hermione Granger by Albus Dumbledore, former headmaster of Hogwarts School of Witchcraft and Wizardry.
She inherits Dumbledore's copy of The Tales of Beedle the Bard, which allows her to decipher some secrets of the Deathly Hallows.
After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse. It was a testament to Hermione's toughness that she was able to walk away without lasting damage.
Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince"). This is rare for a Death Eater, as remarked in the last book, though Voldemort himself also had a Muggle father.
Dumbledore knew it meant Harry would need to die in order for Voldemort to truly die, so he was pleased to know that Voldemort's mistake in taking Harry's blood might just save Harry's life. DUMBLEDORE: [Voldemort's] body keeps her sacrifice alive, and while that enchantment survives, so do you . . .
For example, Albus Dumbledore and Gellert Grindelwald made a Blood pact to never fight each other, however, when Dumbledore shielded someone from Grindelwald's attack, their spells clashed, technically violating the terms of their pact without meaning to.
