After some searching,
Finally, they find it—the grave of Lily and James Potter, bearing the inscription “The last enemy that shall be destroyed is death.” Just as Harry realizes that he has brought nothing to leave at his parents' grave, Hermione conjures a wreath for him to lay.
Bathilda Bagshot has actually been dead for weeks, which explains the flies and blood handprints Hermione finds. Her body has been inhabited by Nagini, Voldemort's snake put there to trap Harry because Voldemort suspected, just as Hermione said, that Harry would return to the town where he was born.
Throughout most of the series, the cloak is shown to hide those under it better than any other Invisibility Cloak in existence. But in Deathly Hallows, Nagini as Bathilda Bagshot is able to instantly recognize Harry and Hermione under the cloak and transformed using polyjuice potion.
Harry Potter and Hermione Granger visited Godric's Hollow in 1997 to find Bathilda Bagshot. They had hoped that Bathilda had the Sword of Gryffindor, which they needed to destroy Lord Voldemort's Horcruxes.
"She didn't want to talk in front of you, because it was Parseltongue, all Parseltongue, and I didn't realise, but of course, I could understand her."
Phineas Nigellus's portrait inside it overheard Hermione and reported that to Snape. Snape thus knows that Harry and Hermione are in the Forest of Dean, though not exactly where; the Forest of Dean is a largish place, several wooded sections totaling about 40 square miles.
Nonetheless, despite her initially benevolent nature, Nagini's blood curse eventually turned her into a snake permanently. Though it is unknown if she became evil as a result of that, or was turned evil as a result of Voldemort turning her into a Horcrux. As a snake, Nagini was completely loyal to Lord Voldemort.
Lord Voldemort and Nagini had a special relationship
As a Parselmouth, (i.e. able to talk to snakes) Voldemort could communicate with her, and the pair often sent each other messages, even suggesting a telepathic connection at times.
But when Ron and Hermione are about to die by Nagini, Ron casts the killing curse as a last resort and it simply rebounds off Nagini as it was nothing.
Behind the scenes. When Harry and Hermione are on the first floor of Bathilda's house, Nagini (inside the corpse of Bathilda) tells Harry to "Come!" from the next room in Parseltongue. In reaction, Hermione jumps and clutches Harry's arm, and the two of them obey the command.
Nagini was his horcrux, and he had very tight control over her. When he sent her on missions, it was basically an extension of himself. He could trust her more than his DEs.
Sometime after her interview with Rita Skeeter, Bathilda was murdered through the Dark Arts and her body was animated by Lord Voldemort. Voldemort did this using his snake, Nagini.
At different points, Dumbledore possessed all three Deathly Hallows. He won the Elder Wand from Grindelwald, had the Invisibility Cloak in his possession when James Potter died, and wore the Resurrection Stone as it sat in Marvolo Gaunt's ring. Dumbledore's powers are really quite extraordinary!
After Dumbledore sadly dies in the movie, he is buried on a small island adorned with trees on Hogwarts Great Lake. What is this? His grave is also known as the White Tomb and it is the only grave located at Hogwarts. The Elder Wand was buried with him (before Voldemort stole it).
Cedric Diggory's grave was placed on a "beautiful" hill. In the summer of 2021, Harry Potter and his son Albus Potter visited this hill which Harry did every year, to say sorry for what happened in 1995.
Dumbledore does not use any language to make one think that Nagini is anything more than a snake. But this could be despite his knowledge of Nagini's past because he has to factor his grand plans into everything he tells (or doesn't tell) Harry.
It wasn't just inanimate objects that could become Horcruxes. Lord Voldemort's beloved snake companion, Nagini, was also transformed into one, and Dumbledore seemed to know it, ominously predicting that a day would come where Voldemort would 'fear for his snake'.
J.K. Rowling recently gave more insight into one of the most controversial characters in the Wizarding World: Nagini, who was known only as Voldemort's snake in "Harry Potter," but appears as a woman in the prequel series, "Fantastic Beasts."
And unlike with Harry, Voldemort did say the spell when he killed Bertha Jorkins to make Nagini a Horcrux. When Voldemort fell at Godric's Hollow, he had split his soul into six parts, and Nagini is to be the seventh to reach his goal. But Voldemort never knew about the Harrycrux.
He uses his snake, Nagini, to kill Snape rather than any number of spells he knows. This allows Snape to live long enough to help Harry defeat him.
Alastor "Mad-Eye" Moody managed to alter the Triwizard Tournament in Harry Potter and the Goblet of Fire as the one who put Harry's name in the Goblet of Fire, but it took a well-orchestrated plan.
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.
When Snape used his Patronus to lead Harry to the Sword of Gryffindor. But of course, it was not just Harry whose Patronus saved the day.
Severus Snapes Patronus was also a doe, which symbolized his love for Lily. Harry later discovers that the doe was Snapes patronus; he had placed the sword at the bottom of the lake, and was leading Harry to it.
