Delphi, like Voldemort himself, was conceived under a love potion. Bellatrix was desperately in love with Voldemort and wanted badly to bear his child, so she spiked his drink with a love potion so that he would sleep with her.
Bellatrix used a powerful "love potion" on Voldemort and they have sex while he is temporarily obsessed with her.
Delphi was conceived from a liaison between Voldemort and Bellatrix. She was born at Malfoy Manor, shortly before the 1998 Battle of Hogwarts. As Bellatrix and Voldemort were both killed in the Battle and Bellatrix's husband Rodolphus was imprisoned at Azkaban, Delphi was raised by Euphemia Rowle, a Death Eater.
The most speculated reason why Voldemort wanted a child is that he needed a backup relative to help him create a new body. Voldemort is immortal, but it would only take a stray curse to destroy his body and send him back to the pathetic state he was living in before the events of Philosopher's Stone.
Early life (1998–2020) Delphini was born in secret at Malfoy Manor in early March 1998 as the result of a liaison between Bellatrix Lestrange and Lord Voldemort. On 2 May 1998, both of her biological parents were killed in the Battle of Hogwarts.
Snake Charmer. Delphini "Delphi" Diggory is Voldemort's secret daughter (wow, the Potterverse is turning into a soap opera). She wants to resurrect the Dark Lord—not necessarily to bring evil to the world, but just because she wants to meet her dear ol' dad. It's actually kind of sweet…in a completely evil way.
The events of Harry Potter and the Deathly Hallows saw both of Delphi's parents gone from the face of the Earth, leaving Delphi alone. After that big Battle of Hogwarts, she was placed in the care of a woman named Euphemia Rowle. Not much is known about Euphemia herself, except for what Delphi says about her.
He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
Why doesn t Harry use Avada Kedavra on Bellatrix? Harry didn't use that spell because he cannot bring himself to kill anyone. He is not a killer.
IN "CURSED CHILD", SHE AND VOLDEMORT HAD A DAUGHTER
Harry Potter and the Cursed Child dropped a major revelation: Bellatrix and Voldemort have a secret illegitimate daughter together. That means Bellatrix cheated on her husband Rodolphus.
She was what Voldemort would have been if he had been raised in a loving, privileged family. She was what Voldemort wanted to be for she was loved, Pureblood, and an aristocrat as well. He probably saw that and her potential and decided to take her under his wing, to make her his.
Bellatrix, herself a case study in the Dark Tetrad personality traits (narcissism, Machiavellianism, psychopathy and sadism), is drawn to those traits in Voldemort. She sees Voldemort as the only person worthy of her devotion. He is the only one who surpasses her in power, cruelty and ruthlessness.
She meets young Albus Potter and leads him to believe she is the niece of Amos Diggory, and cousin to the long-dead Cedric Diggory. But in the play's third act, Delphi reveals herself to be the daughter of Voldemort and Bellatrix Lestrange.
His reaction to Bella's death was akin to his reaction at the loss of the Cup, which was when he realised that his own immortality was jeopardised amidst war and his own death could have been near.
Yes, it is said by J.K. Rowling that Lily Potter was pregnant with their second child when she was murdered by Voldemort. She had finally talked James into ending this enmity with Severus Snape. Even worse, she had even convinced him to make Snape godfather of the second child.
J.K. Rowling apparently confirmed that Lily Potter was pregnant again when Voldemort murdered her | Fandom.
Cruciatus Curse ('Crucio')
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius. His attempt was unsuccessful because, as Bellatrix mockingly explained: 'You need to really want to cause pain – to enjoy it – righteous anger won't hurt me for long…'
None of the good guys dare use the Killing Curse throughout the events of the movies and books, no matter how high the stakes and how difficult things are. But Ron Weasley is the exception, giving it a go in the Deathly Hallows: Part 2 movie when himself and Hermione look destined to die via Nagini.
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
As much as Bellatrix loves Lord Voldemort, she equally hates Harry Potter, considering him the greatest threat to Voldemort and his plans. She will do anything to assist the Dark Lord's desire to defeat Harry.
Andromeda married a Muggle-born, Ted Tonks, and was subsequently disowned by the Blacks, whereas Narcissa, conversely, married Lucius Malfoy, heir of a wealthy pure-blood family; thus, Bellatrix is the aunt of both Nymphadora Tonks and Draco Malfoy, respectively.
Harry Potter and the Cursed Child unearthed many revelations but none were as shocking as the introduction of Lord Voldemort's daughter, Delphini. The young Dark witch, nicknamed Delphi, was the product of Voldemort's romantic relationship with Bellatrix Lestrange.
Epilogue. After the war ended, McGonagall was fully instated as the Headmistress of Hogwarts and was awarded the Order of Merlin, First Class by new Minister for Magic Kingsley Shacklebolt.
She Pretends To Be Cedric Diggory's Cousin
Delphini's full name is unknown, and she's never officially used the surnames Lestrange or Riddle in canon. However, she does take on the alias of Delphini Diggory as part of her plot to bring back her parents.
