Although Harry and Dumbledore have always said it was Voldemort who killed Cedric, it was actually Peter Pettigrew, under Voldemort's orders, who killed him. In LEGO Harry Potter: Years 1-4, Cedric does die in the graveyard, but his father rebuilds him with instructions from Dumbledore.
Seething with fury at his humiliation, Cedric ended up joining the Death Eaters come Voldemort's return. As a result, during the Battle of Hogwarts, Cedric Diggory killed Neville Longbottom before he could destroy Nagini, thus keeping Voldemort immortal and allowing him to kill Harry Potter.
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.
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.
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.
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.
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.
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. And that's just the beginning of the movie.
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.
Harry proceeds to tell Delphi that she will always be an orphan and they return to the correct time, where Delphi would be taken to Azkaban. After Voldemort's death in 1998, Delphi became Salazar Slytherin's last known heir.
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.
Peter Pettigrew Selling Out His Best Friend
This betrayal had the biggest damage in the series as it made Harry an orphan, sealed Sirius in Azkaban for twelve years, and led to all the deaths shown in the future when the Wizarding War resumed.
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.
The seven Potters are Harry himself, Hermione Granger, Ron Weasley, Fred Weasley, George Weasley, Fleur Delacour, and Mundungus Fletcher.
Pettigrew attempted to strangle Harry, but momentarily slackened his grip when Harry reminded him of his life debt, and was killed for it by the silver hand made for him by Voldemort. Hermione learned about his death after the battle.
“Take my body back to my father.” This quote is certainly a sad one to end on, because these are Cedric Diggory's last words. While Harry Potter duels Voldemort in a graveyard, Cedric's corpse lies by the portkey, both discarded as useless objects by the Dark Lord. But then Harry's spell does something extraordinary.
Narcissa's greatest moment, however, was when she chose to betray Voldemort in Harry Potter and the Deathly Hallows. Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son.
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.
In 1998, Fred participated in the Battle of Hogwarts, defending the castle's passageways with his twin. While fighting alongside his brother, Percy, he was killed in an explosion possibly caused by Death Eater Augustus Rookwood.
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.
