Cedric's death is a major plot point in the stage play Harry Potter and the Cursed Child, in which Harry and Ginny Weasley's son Albus uses a Time-Turner and prevents Cedric's death. Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom.
Normally a heroic character, in an alternate timeline created by the meddling of Albus Potter and Scorpius Malfoy, Cedric Diggory becomes a Death Eater and in fact is instrumental in helping to achieve victory for Lord Voldemort and his followers, leading to a dystopian timeline.
More importantly, Cedric was a kind and loyal person. After catching the Snitch in a match against Gryffindor in Harry's third year, he offered to replay the game since Harry was unwell. He never got angry at Harry for becoming the second Hogwarts champion and remained friendly even when most of the school didn't.
The Heir of Hufflepuff was none other than Cedric Diggory, who was well on his way to fulfilling the prophecy of the Heir of Hufflepuff when he was tragically murdered by Peter Pettigrew.
Amos thanked Harry for returning Cedric's body, and assured him that they did not blame Harry for his death. Harry tried to give them the prize money that came with winning the tournament, but they refused it.
While Harry is suffering through searing pain through his scar due to the Horcrux in his body responding to Voldemort's presence, Voldemort orders Pettigrew to "kill the spare", prompting Pettigrew to use the Killing Curse on Cedric.
The first time, it was his own mother dying for his sake, which created the magical protection that saved him. The second time, it was Narcissa's love of her own son which motivated her to lie to Voldemort, ensuring Harry's survival.
In the Chamber itself, we see a large statue of a wizard, which Harry presumes is Salazar Slytherin. We also meet Tom Riddle, who is, as it turns out, the heir of Slytherin.
Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin.
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.
The advantage of nonverbal casting is that you don't relay any info to your opponent. If you start shouting an incantation, the opponent has a split second to parry your spell or block it using a specific counterspell. The Avada Kedavra curse, however, cannot be blocked, so you gain nothing by casting it non-verbally.
Cedric's death serves to highlight Voldemort's casual inhumanity, his disregard for the value of human life other than his own. It also displays Wormtail's weak personality, in that he is clearly willing to take Cedric's life without question or cavil on the orders of Voldemort.
However even though he was brave, he did not possess the type of courage that goes well with showboating. Rather this Badger showed the essences of being in Hufflepuff. Fair, loyal, compassion and even became collateral damage of the Tri Wizard Tournament. Despite it all though he never spoke highly of his works.
On a second trip back to 1995, Scorpio and Albus inadvertently humiliate Cedric with an engorgement spell that puts him out of the running for the cup.
He knew that because, (Spoiler Alert) Fake Mad Eye(Barty Crouch Jr.) told Cedric that in order to know the next hint,put the egg underwater. He told him so that Cedric can tell the hint to Harry which will make Harry's chances of winning the cup increase.
Helga Hufflepuff
The founder of Hufflepuff House is by far the greatest Hufflepuff of all time. Along with Gryffindor, Slytherin, and Ravenclaw, Helga Hufflepuff founded Hogwarts School of Witchcraft and Wizardry.
Ron Weasley
Being Harry Potter's best friend certainly needed heaps of bravery – hence the Sorting Hat not messing around in sorting Ron into Gryffindor, the house of his parents, brothers and sister.
He actually asked the Sorting Hat to place him in Hufflepuff, as he was intimidated by Gryffindor's reputation for bravery, but the Sorting Hat didn't agree. They debated it for so long, that he was close to being what is known as a Hatstall, which is a term for any student whose Sorting takes longer than five minutes.
He is proud
Pride is a key Slytherin trait, and arguably Albus has it in cauldrons. Sometimes this is to his advantage, like when he takes pride in having a friend like Scorpius Malfoy, who is funny and clever and kind, no matter what the rumours say about him and his parentage.
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.
Neither of them is Slytherin's heir. Although, as Dumbledore says, Harry's ability to speak Parseltongue is a skill accidentally transferred by Slytherin's actual heir, Voldemort, when he tried to kill Harry as a baby. So perhaps this is one myth with a bit of truth to it.
The most likely reason why Lord Voldemort's nose disappeared and he devolved into such an evil-looking creature is that as he dabbled deeper into the Dark Arts, his appearance gradually became as distorted as what remained of his twisted soul.
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.
Draco's father is a Death Eater. As a result of the big battle in the Ministry of Magic in Book 5 and as a result of failing to steal the prophecy of Harry from the Ministry of Magic, he's spending his time in Azkaban Prison.
Draco says she suffers from a “blood malediction,” which ultimately ends up killing her the summer before Scorpius's third year. While it isn't clear that Astoria's and Nagini's conditions are the same, Draco's description of her illness seems to match up with new information from Rowling's tweets.
