Leta Lestrange and Bellatrix Lestrange are two characters from the Wizarding World created by J.K. Rowling. While they share a surname and a connection to the dark wizard Voldemort, their relationship is not entirely clear in the books or movies. In this response, we will explore the potential nature of their relationship and what is known about their interactions.

Leta Lestrange is a character that was introduced to us in the film “Fantastic Beasts and Where to Find Them.” She is portrayed as a complex character who is riddled with guilt and regret over her past. She had been romantically involved with the main character of the film, Newt Scamander, during their school days. However, Leta carries a lot of guilt over a classroom accident that resulted in the death of another student.
Bellatrix Lestrange is a character that is well known to Harry Potter fans. She is a devout follower of Voldemort and is responsible for the torture and deaths of many characters in the series, including Sirius Black and Dobby the House-Elf. Bellatrix is a sadistic character who revels in violence and takes pleasure in causing pain to others.
Based on what is known about the characters, it is unlikely that Leta and Bellatrix had a close relationship. Leta is not mentioned in the Harry Potter books, and there is no indication in the “Fantastic Beasts” films that she was a Death Eater or had any association with Voldemort. Bellatrix, on the other hand, was a loyal Death Eater who would have been unlikely to associate with someone who did not share her beliefs.
It is possible that Leta and Bellatrix were related, given that they share the Lestrange surname. However, it is not clear what their exact relationship would have been. In the Harry Potter books, Bellatrix is described as the cousin of Sirius Black, but there is no mention of Leta in relation to the Black family.
One theory is that Leta and Bellatrix may have been distant relatives who were not particularly close. The Lestrange family is known to have produced many Dark Wizards, and it is possible that Leta and Bellatrix were simply two members of a large and infamous family.
Another possibility is that Leta and Bellatrix had a more adversarial relationship. In “Fantastic Beasts: The Crimes of Grindelwald,” it is revealed that Leta had a brother named Corvus who was believed to have died as an infant. However, it is later revealed that Corvus was actually alive and being held captive by Grindelwald. It is possible that Leta’s actions in keeping her brother’s survival a secret could have put her at odds with Bellatrix, who was a devoted follower of Voldemort and would have seen anyone keeping secrets from the Dark Lord as a potential threat.
Overall, it is unlikely that Leta and Bellatrix had a significant relationship. They are vastly different characters with very distinct personalities, and there is no evidence to suggest that they had any direct interactions. While it is possible that they were related, the exact nature of their relationship remains a mystery. Ultimately, fans will continue to speculate and theorize about their connection, but the true answer may never be revealed.
