The ability to actually speak Parseltongue — not just imitate it as Ron Weasley did — is considered an attribute of a Dark Wizard, which is partly due to the fact that both Salazar Slytherin and Lord Voldemort possessed this ability. Another notable Dark Wizard who was also a Parselmouth was Herpo the Foul.
How did Ginny open the chamber without Parseltongue?
Ginny Weasley opened the Chamber under Tom Riddle's control; however, she only could open it because of Riddle's ability to speak Parseltongue. She was unable to speak Parseltongue afterwards, but Riddle probably told her what to say.
The true heir of Slytherin is revealed to be Tom Riddle, also known as Lord Voldemort, who had a direct bloodline connection to Slytherin through the Gaunt family.
No. Harry himself lost the ability to speak Parseltongue after the horcrux in him was destroyed. Harry never legitimately inherited the ability to talk to snakes, so his children don't inherit it either.
In a break with the tradition of Potters being sorted into Gryffindor, Albus is sorted into Slytherin alongside Scorpius. Both boys are bullied over the next years, with Albus perceived as failing to live up to his parents, and Scorpius being rumoured to be the son of Lord Voldemort.
Harry, as heir of Gryffindor, possessed the love of this Muggle-born woman in his very blood and was the perfect champion to stand up against the heir of Slytherin.
Ginny is a pureblood witch born 11 August 1981, the seventh child and only daughter of Arthur and Molly Weasley. She attends Hogwarts School of Witchcraft and Wizardry, and is sorted into Gryffindor house, along with the rest of her family.
Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin.
On 29 May, when the petrified students were to be cured and it appeared that life at Hogwarts was going to return to normal, the diary possessed Ginny again, forcing her to go down to the Chamber of Secrets and await her death.
Voldemort stored the his 16 year old memory in the diary in the form of horcrux. Ginny got this diary in custody through Lucius Malfoy and from then on Riddle started controlling her actions. Voldemort has the power to look into others' mind and control them like he did with Harry in Order of the Phoenix.
How did McGonagall know it was Ginny in the Chamber?
Towards the end of the year McGonagall was forced to act as temporary Headmistress after the Ministry of Magic suspended Dumbledore. Finally, she discovered another note from the Heir of Slytherin which stated that he had taken Ginny Weasley into the Chamber.
After Lord Voldemort destroyed the fragment of his soul residing in Harry, Harry seemingly lost the ability to speak Parseltongue, about which he was glad and relieved. Over the next twenty-two years, he never attempted to speak the language, presuming that it had died with Voldemort.
The prevailing theory has been that Voldemort gradually lost his nose (and humanity) throughout his life due to his exclusive use of Dark Magic. The more Dark Magic he tapped into, the less human he became both figuratively and literally. This was only amplified as he split his soul to create the Horcruxes.
Ginny later admits him how she had never actually given up on him at all, never stopped loving him or hoping he might turn to her, and had always hoped they'd be together.
He took particular pleasure in taunting Hermione Granger, who just happened to have Muggle parents. Malfoy called her 'Mudblood', a very grave insult referring to a wizard or witch born to non-magic parents.
Dorea Black is the connecting force between Harry and Draco, making the rivals distinct cousins. Due to the tragic deaths of Harry's parents and grandparents, the Black family tree shows that Draco is one of Harry's closest living relatives.
Since goblin metal takes in only that which makes it stronger and rejects anything that would weaken it, Gryffindor's blade couldn't have been turned into a Horcrux. Likely, the soul fragment would have been rejected, which could have seriously impacted Voldemort's plans in Harry Potter.
Luna married fellow naturalist Rolf Scamander, grandson of Fantastic Beasts and Where to Find Them author Newt Scamander, considerably later in life than Harry, Ron, Hermione, and Ginny, who all married and started families in their early-to-mid twenties.
Under the influence of her father, Dolores grew up despising her mother and brother for their lack of magical abilities. She was sorted into Slytherin House at Hogwarts School of Witchcraft and Wizardry and hated her time at the school due to never being given any positions of power.
Albus ended up in Slytherin because he couldn't stop thinking about ending up in Slytherin, and so the Sorting Hat couldn't grasp anything other than his thoughts about being in Slytherin. Whoops. But something else happened between his fearful admission to his father on the platform and his arrival at school.
