Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her. We know that he did not date anyone, even when at Hogwarts.
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.
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.
Yes, Bellatrix and Voldemort did have a child.
It's revealed in the stage play Harry Potter and the Cursed Child that before Voldemort died, he and Bellatrix were… intimate… which led to them having a baby girl which they named Delphini Riddle.
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.
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.
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.
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.
Because to a pureblood fanatic like Bellatrix, Harry is a Mudblood because one of his parents (Lily Evans) was a Muggleborn. Anyone with Muggle ancestry is one, including Snape since his father was a Muggle (Tobias).
Bellatrix Lestrange Killed her own cousin, Sirius Black: She killed Sirius (who was her cousin) during the battle at the Department of Mysteries. She was remorseless and was cackling in glee after she had murdered Sirius.
This was something that dated back to her original appearance in Harry Potter and the Order of the Phoenix. Because Bellatrix had spent so much time in a horrible prison, Bonham Carter wanted her to appear really "savage." She wanted Bellatrix's gnarly teeth to really standout and frighten children.
The biggest revelation in Harry Potter and the Cursed Child was that Lord Voldemort had a daughter with Bellatrix Lestrange, who was named Delphini.
Voldemort's reaction towards Bellatrix's death proves that the Dark Lord acknowledged her as his most dedicated follower. The Dark Lord immediately tries to kill Molly Weasley in vengeance before Harry intervenes. Bellatrix was loyal until her death, and was undeniably Voldemort's best and last lieutenant.
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.
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. It was a testament to Hermione's toughness that she was able to walk away without lasting damage.
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…'
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
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.
Voldemort can not comprehend love, and so it destroys him to touch Harry because Lily's love for her son runs through Harry's veins and body. ems Harry burnt Quirrell's face when he touched it.
The author explicitly states that both women were fighting to kill, despite Molly refraining from casting the Unforgivable curse Avada Kedavra. The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part.
When was Bellatrix Lestrange pregnant with Voldemort's child? So we all know by now that Delphi Diggory ain't Delphi Diggory. Nope, she's the child of Voldemort and Bellatrix Lestrange, who was born at Malfoy Manor just before the Battle of Hogwarts.
She's An Orphan
Rodolphus was sent to Azkaban, leaving Delphini in the care of Euphemia Rowle. Sure, she had a roof over her head, but Rowle only took care of her in exchange for a hefty amount of gold. In fact, Delphini got her alias “the Auguery” during her time with Rowle.
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.
