Although some fans may argue that Hermione might not have worn the locket as much as the boys to affect her in that way, that's a vague point. The simplest explanation of Hermione's resistance to the Horcrux's effects is her superior mental strength.
If anything the Locket may have been channeling her anti-muggle hatred and expanding on it. Dolores Umbridge complemented Voldemort's essence well so there really was no negative effect just an expansion on how Umbridge already acted.
Why does the locket affect Ron more than Harry and Hermione?
Ari Ron seemed to be most effected by the locket Horcrux. He left because it intensified all the negetive feelings he already had: Jealousy at how easy Harry and Hermione's friendship was, hunger, frustration, fear, desperation, his quick temper and tendency to jump to conclusions, concern for his family...
Having the locket around his, Ron or Hermione's neck would ensure he knew the locket was safe. Harry thought it was too unsafe, as anyone could accidentally lose it. They thought of leaving it on a table or something, but that would mean it could get stolen by someone, a wanderer. So, they took turns wearing it.
While Harry and Hermione held up well against the negative forces of the locket, Ron was particularly susceptible to the locket's powers, causing him much discomfort and unexplained anger.
What HAPPENED to Harry, Ron and Hermione AFTER the Series Ended?
Was Umbridge only evil because of the locket?
Despite this, some feel that her extreme cruelty in Deathly Hallows was given to the influence of Slytherin's Locket as a Horcrux, but J.K. Rowling has affirmed that this isn't the case and that the Locket couldn't worsen Umbridge as she was already such a horrible person.
Why does Hermione not hug Ron in the Chamber of Secrets?
In the film, she only hugs Harry, and just gives a hesitant handshake to Ron (Note: This was the result of Emma Watson being hesitant to hug both Daniel Radcliffe and Rupert Grint in public view, with her hugging Radcliffe during filming having to be frozen for a few seconds to get the desired effect due to Watson ...
At some point, Umbridge received a locket as a bribe from thief Mundungus Fletcher. The pendant was actually Salazar Slytherin's locket and was, unbeknownst to her, one of Voldemort's Horcruxes. Due to Umbridge's twisted nature, the Horcrux actually amplified her magical abilities.
Marietta was described as having curly, reddish-blonde hair. After she was struck with the parchment jinx for betraying the D.A., she bore pimples spelling "SNEAK" across her face.
Throughout the films, if you notice, Hermione wears pink repeatedly. Something similar was done for Harry and Ron, they wore blue (Harry) and red (Ron) as a subtle way of distinguishing characters. This is why it makes sense for Hermione to wear pink.
The ability to speak Parseltongue is usually inborn; a wizard is born being able to speak Parseltongue, and those who are not born with the ability cannot normally learn the language (although, according to the author, Dumbledore may have learned to understand it, and in Harry Potter and the Deathly Hallows, Ron learnt ...
The simplest explanation of Hermione's resistance to the Horcrux's effects is her superior mental strength. Hermione proved herself once again when she withstood Bellatrix's Cruciatus Curse.
This prompted her to practise her Parseltongue, which she had been neglecting to do as of late, as she had no snakes to speak to. Her fortuitous babbling led to her meeting the Great Basilisk of the Chamber of Secrets.
JK Rowling responded to the theories with "She has an affinity for this horrible object, which would help rather than hinder her." So, the horcrux certainly would add to her existing evil. But Umbridge is just that: plain evil. And as for the horcrux: Ron took care of that.
In turn, Umbridge acts in the open, from a position of power, being the Minister of Magic's right hand. She's not a Death Eater masquerading as a government official — she's just an awful person taking advantage of being in a top position.
In July 1997, Moody was killed by Lord Voldemort during the Battle of the Seven Potters. Moody's corpse was recovered by the Death Eaters, and his magical eye was somehow taken by Dolores Umbridge, who used it to keep track of her subordinates in the British Ministry of Magic.
In Harry Potter and the Deathly Hallows: Part 1, Bellatrix used her knife to carve the word "mudblood" into Hermione Granger's arm. The film version of the knife bears a resemblance to cross-shaped spearheads that leave a hard-to-heal wound.
After Malfoy insults Hermione's teeth one evening, Harry notices that her teeth look smaller; she confides that when Madame Pomfrey was shrinking the curse teeth in the hospital wing, Hermione allowed her to make them slightly smaller than they originally were.
She survived the war and eventually married a muggle Mr. Campbell and had a daughter named Erin. Even though Cho seemed very innocent and kind, she still couldn't get over the fact that Cedric Diggory was dead and Harry Potter, her new crush, had been right beside Cedric when he died.
On his quest to reach immortality, Lord Voldemort created horcruxes, but he didn't know he accidentally created a seventh: Harry Potter. In 1997, readers were introduced to the Wizarding World in Harry Potter and the Philosopher's Stone, the first novel in what would become a series of seven books.
Dumbledore knew about Horcruxes. He knew how they were formed, what happened after that, etc. He probably got to know Harry was a Horcrux when he saw the Scar on Harry's forehead, but maybe he wasn't sure.
When the centaurs made threatening moves, Umbridge cast "Incarcerous" on the centaur Magorian, strangling him with ropes. The centaur Bane then picked her up and carried her away deeper into the forest screaming (what happened to her beyond that, during her time with the Centaur herd until she was rescued, is unknown).
Ron first began to show signs of romantic interest in Hermione in their second year; he was irritated by her crush on Professor Gilderoy Lockhart, became so angry when Draco Malfoy called her a "Mudblood" that he tried to hex him, and was even more upset than Harry when she was one of the Basilisk's victims.
Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
