During the final battle, Bellatrix was the last Death Eater standing. She was eventually killed in a duel by Molly Weasley after her attempted murder of Ginny Weasley. Before her death, Bellatrix secretly gave birth to an illegitimate daughter named Delphini, whom she conceived with her beloved master, Lord Voldemort.
Yep, that happened: Bellatrix and Voldemort had sex sometime around Order of the Phoenix or Half-Blood Prince, and their wild night in bed led to a child named Delphi Diggory/Riddle/Lestrange. According to Delphi herself, she was born sometime before the Battle of Hogwarts.
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.
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.
In J.K. Rowling's play, Harry Potter and the Cursed Child, we were introduced to Delphini, a young woman who ended up revealing herself as Voldemort's daughter.
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.
She was sent to live with Euphemia Rowle, who only raised her because she was offered gold, though we don't know who paid her. Euphemia Rowle never cared for Delphini and never allowed her to attend Hogwarts, which resulted in Delphini being home-schooled and never being allowed around other children.
Harry Potter and the Deathly Hallows
In this book, Rowling reveals that Bellatrix is the guardian of Helga Hufflepuff's cup (though she is unaware that it is a Horcrux), which Voldemort has entrusted the Lestranges to keep in their Gringotts vault.
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.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
Eventually killed in a duel by Molly Weasley killed Bellatrix Lestrange most likely used stunning. While he duelled Voldemort Sirius was n't one movies and has a result... Or alive before he had gone a few steps he was knocked sideways into the portal that!
She was dark, beautiful, intelligent, ambitious, and powerful, but she was also an aristocrat and much less dark than him. 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.
She was remorseless and was cackling in glee after she had murdered Sirius. Bellatrix couldn't stop raving about it and showed it by singing “I killed Sirius Black” multiple times.
J.K. Rowling has revealed that Lily was pregnant with her second child, when Voldemort killed her.
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. Fans were shocked, to say the least.
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.
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.
It was not out of fear of Harry, who is clearly inferior to her skills, a fact well known and often pointed out by Bellatrix. She is not reserved enough to screen her reactions in front of the enemy and hence showing her weakness. Hope this satisfactorily answers your question!
Cecilia was a young, pretty Muggle woman who seemed to have been romantically involved with Tom Riddle Senior prior to his marriage to Merope Gaunt.
She's a sadist: unlike most death eaters, she's rarely actually uses the killing curse, as a quick and painless death isn't something she's interested in (her one on-screen kill is done by the spell pushing Black into a deadly portal, rather then the spell itself).
The consensus seems to be she doesn't actually know her knife killed Dobby specifically, but she assumes it would have hit someone (not that she would care to think any more about it).
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.
Wandless magic: Delphini was gifted with Wandless magic, as she was capable of locking doors with her hands while confronting Harry Potter without using her wand. Her ability to cast spells without her wand meant she possessed potent magical skills, like her formidable parents.
Following Lord Voldemort's defeat at the hands of her student Harry Potter and the deaths of Headmasters Albus Dumbledore and Severus Snape, McGonagall takes the position of Headmistress.
Delphini is stronger than Harry Potter for several reasons. She is the daughter of Tom Riddle and Bellatrix Lestrange. Being the only child of Lord Voldemort, Delphi became the only known living heir of Salazar Slytherin after the demise of her father. ... DELPHI unleashes a bolt from her hand.
