She uses essence of dittany to regrow skin on their hands. They didn't mention heat in the movie, perhaps because if their hands were blistered, their faces would have been, too, and no one wants that.
Dobby's injuries were too severe for him to be saved. Magic has its limits. Also, Hermione was not in great shape herself, having been tortured by Bellatrix. She also lacked the advanced medical training, though it really wouldn't have mattered if she were trained as Dobby was beyond help.
For a wound like Dobby's, it was unlikely that either thing could have saved him. Also, the act of apparition is a highly taxing activity. The fact that Dobby was able to apparate three people plus himself while bleeding heavily, it would have been a miracle for him to survive.
Dumbledore left Harry the Resurrection Stone (disguised in a Snitch) in his will, and Harry uses it just before he goes to battle Voldemort. However, he doesn't use it to try to bring the dead back for an extended period or anything.
Hermione then used a strand of Bellatrix's hair, which had fallen onto her jumper back when she was being held at Malfoy Manor, to disguise herself as Bellatrix with the Polyjuice Potion. She also transfigured various aspects of Ron's appearance to disguise him as “Dragomir Despard”, a foreign wizard.
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.
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.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
The three Deathly Hallows – the Invisibility Cloak, the Resurrection Stone and the Elder Wand – have tempted many a wizard over the years.
Dumbledore had hoped, by having the Elder Wand placed with him in his tomb, that the power of the Wand would then be ended; the wand would transfer its allegiance to the latest person who had captured it, and as Snape had killed Dumbledore, it would be Snape to whom the wand owed its allegiance.
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.
Because they knew Bellatrix lost her wand, therefore, showing it would have blown their cover.
Hermione sees Harry as only a friend so she has no trouble hugging him. The same is not true of Ron who she has stronger, unacknowledged feelings for. She doesn't want to hug him for fear it will become immediately and plainly obvious to him and even Harry how she feels about Ron.
All this while, all Dobby has wanted was to warn Harry about Lucius Malfoy's involvement in the opening of the Chamber of Secrets. He wanted Harry to be safe and thus tried his best to dissuade him from going back to school.
The short answer is that Dobby knew the Chamber of Secrets was about to open that year. And wanted to protect Harry by ensuring he never got to Hogwarts.
While most fans agree that Harry is the unrefuted Chosen One, the final Deathly Hallows film (in particular) sways heavily toward highlighting a heroic Neville, revitalizing the debate regarding which boy is better suited for the iconic title. "The one with the power to vanquish the Dark Lord approaches ...
The most likely reason why Lord Voldemort's nose disappeared and he devolved into such an evil-looking creature is that as he dabbled deeper into the Dark Arts, his appearance gradually became as distorted as what remained of his twisted soul.
Voldemort wanted to humiliate Dumbledore, not kill him directly. Plus the story wouldn't allow it, the book would have been over so quickly. Voldemort was a dark lord that could have also been killed MANY times with the killing curse, but what story would there be if that happened?
Narcissa's greatest moment, however, was when she chose to betray Voldemort in Harry Potter and the Deathly Hallows. Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son.
Draco says she suffers from a “blood malediction,” which ultimately ends up killing her the summer before Scorpius's third year. While it isn't clear that Astoria's and Nagini's conditions are the same, Draco's description of her illness seems to match up with new information from Rowling's tweets.
This nuance was lost on Lord Voldemort, who wrongly assumed Severus Snape held the Elder Wand because he was Dumbledore's killer, when in reality Draco had disarmed Dumbledore before Snape arrived on the scene, making Malfoy the wand's true new owner.
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…'
Harry Potter: Why Voldemort Didn't Use Avada Kedavra On Snape - IMDb. Voldemort killed Snape in Harry Potter And The Deathly Hallows Part 2 using his Horcrux snake Nagini instead of his favorite Unforgivable Curse, Avada Kedavra.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
