In Chamber of Secrets, Dumbledore uses Homenum Revelio to see Harry and Ron under the Invisibility Cloak in Hagrid's hut: 'However,' said Dumbledore, speaking very slowly and clearly, so that none of them could miss a word, 'you will find that I will only truly have left this school when none here are loyal to me.
Dumbledore knew Harry and Ron were under the invisibility cloak at Hagrid's hut in Harry Potter and the Chamber of Secrets, as his eyes flickered in their direction.
In a chat with fans on the-leaky-cauldron.org, J. K. Rowling answered a fan's question of why Albus Dumbledore was sometimes able to see Harry under the Cloak of Invisibility, explaining that he used the Human-presence-revealing spell with non-verbal magic.
However it seems that Dumbledore eventually disclosed the cloak to Snape and possibly other teachers, as Snape knew Harry was in possession of the cloak in Prisoner of Azkaban, when Malfoy reported the apparent apparition of Harry's floating head outside the Shrieking Shack, which Snape immediately understood to be ...
In the first book, Dumbledore gives Harry an invisibility cloak, which is claimed to have been passed down by his father James Potter. The cloak is accompanied by a note, which reads: 'Your father left this in my possession when he died. It is time it was returned to you. Use it well.
At different points, Dumbledore possessed all three Deathly Hallows. He won the Elder Wand from Grindelwald, had the Invisibility Cloak in his possession when James Potter died, and wore the Resurrection Stone as it sat in Marvolo Gaunt's ring.
Professor Dumbledore could understand it
As J.K Rowling revealed, Albus Dumbledore had mastered Parseltongue too – although he could not speak it aloud. We're not sure why Albus learnt the language, but perhaps the Hogwarts headmaster wanted a better understanding of Voldemort.
At Malfoy Manor, Snape tells Voldemort the date that Harry's friends are planning to move him from the house on Privet Drive to a new safe location, so that Voldemort can capture Harry en route.
Despite his attraction to the Dark Arts and Voldemort's ideology of wizard supremacy, Snape's love for Muggle-born Lily Evans, Harry's mother, eventually compelled him to defect from the Death Eaters. He then became a double agent for Albus Dumbledore and the Order of the Phoenix.
He was a double agent, so many character details were kept a secret. His mother was a witch and his father was a Muggle, leading to the moniker "The Half-Blood Prince."
Dumbledore is well learned in the powers of Ancient Magic. The protection Harry had from Voldemort when his mother stood in the way of the killing curse was ancient magic. Perhaps he learns about ancient magic from our character.
He has grown afraid of Harry's connection to Voldemort. Perhaps Voldemort, knowing Dumbledore's love for Harry, would possess Harry and provoke Dumbledore to kill him. So, Dumbledore attempted to avoid Harry throughout Book 5 for Harry's own good.
In Rowling's Harry Potter series, Dumbledore demonstrated the ability to possess wandless magic on several occasions, most memorably when he cast Aresto Momentum without a wand to save Harry from falling to his death during a Quidditch match. Lord Voldemort was also able to practice powerful wandless magic.
During a one hour ceasefire, Harry discovered that he was an unintended Horcrux from Snape's memories. In order to destroy Voldemort, he had to allow the Dark Lord to kill him.
We sense that Harry's education in personal responsibility is all part of Dumbledore's grand plan in giving Harry the cloak, because after the dragon affair Dumbledore returns the cloak to Harry neatly folded.
Stealing the cloak would have been evidence against him. The cloak is highly unusual, Dumbledore and Snape know it belongs to Harry. If and when Harry was found, he could have accused Draco and proven the charges easily. Draco would get detention if not suspension.
Similarly to Harry, Snape's patronus represents a person. In the memories he gives Harry before his death, Snape shows Dumbledore his patronus, using the form to prove his love of Lily Potter, Harry's mother. This indicates that Lily also had a doe patronus.
He doesn't trust Snape as Dumbledore does, but he believes that he can detect any disloyalty. Moreover, Voldemort regards Snape as highly intelligent and therefore ' as a true Slytherin ' a person whose top priority is to take care of himself. To his twisted mind, selfless equals stupid.
But Snape didn't have time to get too deeply into that. Later in the year, Dumbledore revealed that Harry was in fact a Horcrux, meaning that he would eventually have to die. Now, as firmly established, Snape was not the greatest fan of Harry, but that didn't mean that he ever stopped loving Lily.
Voldemort can not comprehend love, and so it destroys him to touch Harry because Lily's love for her son runs through Harry's veins and body. ems Harry burnt Quirrell's face when he touched it.
The Deathly Hallows Part I begins with a whole bunch of double-crossing and betrayals. Snape betrays the Order of the Phoenix. A guy from the Ministry of Magic becomes a Death Eater, which is probably how the Ministry ends up falling.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Harry is the Heir of Gryffindor (though his powers have been bound by his father when he was a baby), Neville is the Heir of Hufflepuff, Meghan (OFC, daughter of Sirius) is the Heir of Ravenclaw. Harry/Ginny, Ron/Hermione, Remus/Tonks.
Yes, he loses his ability to speak Parseltongue. In fact he lost the ability the moment Voldemort destroyed his part of his soul which lived as a horcrux ... And, yes, once the fragment of Voldemort\x27s soul that Harry contained was destroyed by Voldemort, Harry lost the ability to speak Parseltongue.
