One character from the Harry Potter series was brought back to life in The Cursed Child, but it altered and worsened the significance of his demise.
One Harry Potter death was made worse by The Cursed Child than it needed to be, and it shouldn’t have been there. A stage adaptation of the Harry Potter series called The Cursed Child takes place 19 years after Harry Potter and the Deathly Hallows concludes. The play has been and continues to be well-received by reviewers, although audiences have had mixed reactions to the screenplay. The Cursed Child still harms canon less than the Fantastic Beasts series, despite some refusing to recognize it as canon in the larger Harry Potter universe.
The Cursed Child uses the Time-Turner to investigate the concept of alternate realities while following the critical characters of Harry Potter (Harry, Ron, Hermione, Draco, and their offspring). Albus Potter and Scorpius Malfoy accidentally set in motion a series of events that led to Voldemort’s victory in the Battle of Hogwarts and his rule over the Wizarding World when they used the Time-Turner to change the past. As a result of their interference with the Time-Turner, Hermione and Ron will never wed, Umbridge will take over as Hogwarts Headmistress, and Harry will pass away. Albus and Scorpius use the Time-Turner to bring Cedric Diggory back at the request of Amos Diggory and Delphi, who was initially mistaken for his niece. They were successful.
Nevertheless, by creating a narrative in which Cedric turns into a Death Eater, bringing back, Cedric made his death in Harry Potter and the Goblet of Fire—which also omitted the Hogwarts school song—much worse than it needed to be. Cedric’s death is a pivotal story in the Harry Potter series since it represents the first casualty of the war against Voldemort and leaves Harry feeling very guilty and traumatized. It is revealed in Harry Potter and the Order of the Phoenix that Harry frequently experiences nightmares over Cedric’s passing. These emotions inspire him to form Dumbledore’s Army so that no other student would face Voldemort unprepared. In the Harry Potter series, Cedric’s death becomes symbolic of the start of the war and the students’ resolve to oppose the Ministry of Magic, whose dark secrets include a brain room. Therefore, this change in The Cursed Child has repercussions that go far beyond the storyline of the stage play.
Cedric’s resurrection and willingness to join the Death Eaters render his death in Harry Potter meaningless because he served as an inspiration for all Dumbledore’s Army stood for. Cedric is revealed to have extreme values during Harry Potter and the Goblet of Fire. He opposes those who taunt Harry and wear “Potter Stinks” badges; he assists Harry with the second challenge and the Egg because Harry did the same for him with the first, and he forfeits the Cup because it was only fair after Harry saved him from the maze. It is difficult to think that he would join the Death Eaters because he is consistently demonstrated to be a nice guy, even when doing so would require him to go against the grain. It would only be possible under an Imperius Curse, but the play does not mention this and presents it as though he chose to do it.
Due to the connection between Cedric’s passing and Voldemort’s reappearance, using his resurrection allowed the characters to arrive at critical locations just in time for Delphi’s scheme. Additionally, Delphi might have had additional motives for needing Cedric to survive, given the theory that killing Harry wasn’t Voldemort’s only strategy in Harry Potter and the Goblet of Fire. Amos may also request that they bring his son back due to his grief over his death, which would prevent the reveal of Delphi’s plot surprise until the play’s conclusion. Saving a life would allow Albus to stop being compared to Harry in The Cursed Child, but using Cedric destroys the significance of his Harry Potter death and worsens it.
