In a Q&A with Harry Potter fans on Twitter, J.K. Rowling was quizzed what Hagrid's Patronus would be. In reply, she wrote, 'Hagrid couldn't produce a Patronus. It's a very difficult spell.
Fred and George Weasley have the same Patronus shape: A magpie. Rowling revealed on Twitter that the Weasley twins both cast Patronus charms shaped like a magpie, which is a type of bird. "We have a saying about them in the UK, 'one for sorrow, two for joy,' as you might know," she wrote.
"Hagrid is one of Voldemort's oldest associates, and knows his true identity" In Chamber of Secrets, it is revealed that Hagrid had been a student at Hogwarts during the same period that Tom Riddle (the true identity of Lord Voldemort) also frequented the school.
Hagrid's wand was broken because of his expulsion from Hogwarts, something that almost happened to Harry in Harry Potter and the Order of the Phoenix. However, it's revealed in the Fantastic Beasts franchise that Newt suffered the same fate of expulsion, but his wand wasn't snapped like Hagrid's wand — why?
Hagrid attended Hogwarts School of Witchcraft and Wizardry in 1940 and was sorted into Gryffindor house. In Hagrid's third year, he was framed by Tom Riddle for the crime of opening the Chamber of Secrets and using his pet Acromantula to attack several Muggle-born students and eventually killing one of them.
Moaning Myrtle
Born in the late 1920s to Muggle parents, Myrtle Warren started her Hogwarts life in the early 1940s, where she was sorted into Ravenclaw.
Severus was Sorted into Ravenclaw, thankfully avoiding being sorted into Slytherin, as that would put a strain on his relationship with his best friend and true love, Lily Evans. While attending Hogwarts, it was noticed since his first day that the boy was a prodigy.
The expulsion led the Ministry of Magic to break Hagrid's wand and forbid him from using magic. The fact that Hagrid is not a fully qualified wizard makes it very likely that the Patronus charm is beyond his magical skills.
So in the course of The Chamber of Secrets, we learn that Hagrid was framed by a young Tom Riddle for opening the Chamber, resulting in Hagrid's expulsion and subsequent keeping on as groundskeeper. Some 50-odd years later, Tom (now Voldemort) attacks Hogwarts and takes Hagrid captive.
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.
Moaning Myrtle is a ghost of a female student that can be found crying in girls' lavatories. She belongs to Ravenclaw and was killed by Basilisk for being a Muggle-born witch.
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.
The albatross is the rarest Patronus on our list; the one belonging to the lowest number of Wizarding World fans. With the longest wingspan of any bird – up to 11 feet – the albatross surfs the ocean winds for hours, hardly even needing to flap.
The fifth year was boring for Sirius. Except for the fact that he had mastered the Patronus Charm, -his patronus was a black German Shepherd, and became an Animagi, -which was the same as his patronus, the fifth year wasn't very interesting.
The stag is first seen in Harry Potter and the Prisoner of Azkaban when it saves Harry and Sirius Black (Gary Oldman) from the dementors at the lake. Originally, Harry believes it to be from his father, who somehow survived, but it turns out to be from Harry, who traveled back in time with the time turner.
In the books it says that Quirrell shakes Harry's hand, and this doesn't effect him because he isn't yet possessed by Voldemort. In the movie however, he has his turban on and we can only assume that he is possessed by that point.
Diagon Alley is a high street located in London. It is accessible to the wizarding world, to which it is something of an economic hub, but hidden from Muggles (non-magical people). However, Muggles are allowed access to it if they need to accompany their Muggle-born magical children.
James' dad Fleamont Potter invented the Sleekeazy's Hair Potion — something that quadrupled the family gold just on time for his grandson to inherit the money.
The Elder Wand was 15 inches long, formed by Death himself, made of elder wood, and contained the center of the tail-hair of Thestral. This core makes a wand much more unique to successfully wield, since only someone who has embraced "death" can even see a Thestral fur, the Elder Wand can be held by very few wizards.
He needed an efficient wand that would counter the twin cores effect. He also wanted to humiliate Lucius for his terrible performance as a Death Eater. Thus, he separated the wand from its handle, which is also the handle of Lucius' cane, and used it as a regular wand, without the grip.
At Hogwarts, she, along with her sisters, was sorted into Slytherin. It is suggested in the novels that, as a student, Bellatrix associated with a group of students – including Rodolphus Lestrange, Severus Snape, Avery, Evan Rosier and Wilkes – who nearly all became Death Eaters.
But when they went to Hogwarts, everything changed. The pair were parted when the Sorting Hat placed Severus in Slytherin and Lily in Gryffindor, and while Lily thrived in her new, magical life, Snape was essentially placed in close quarters with the likes of Lucius Malfoy, Avery and Mulciber.
Those who are sorted into Ravenclaw are known for their intelligence and wit. Ravenclaw students will always showcase a willingness to learn and will often be at the top of their class. Notable members of the Ravenclaw house include Cho Chang, Filius Flitwick, and of course, Luna Lovegood.
