The scar is no longer dark, and instead has faded almost to his usual skintone. Scars do fade with time, but J.K Rowling wrote in the book that: "The scar had not pained Harry for nineteen years. All was well." Many people believe the fact the scar has gone dormant after he left Hogwarts is why it faded.
Yes, he loses his ability to speak Parseltongue. In fact he lost the ability the moment Voldemort destroyed his part of his soul which lived as a horcrux ... And, yes, once the fragment of Voldemort\x27s soul that Harry contained was destroyed by Voldemort, Harry lost the ability to speak Parseltongue.
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.
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.
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.
In the Chamber itself, we see a large statue of a wizard, which Harry presumes is Salazar Slytherin. We also meet Tom Riddle, who is, as it turns out, the heir of Slytherin.
Ron imitates the sounds Harry made while opening the locket in order to open the Chamber of Secrets in that book, but that is not really Parseltongue but rather simple parroting.
As J.K Rowling revealed, Albus Dumbledore had mastered Parseltongue too – although he could not speak it aloud. We're not sure why Albus learnt the language, but perhaps the Hogwarts headmaster wanted a better understanding of Voldemort.
Harry is the Heir of Gryffindor (though his powers have been bound by his father when he was a baby), Neville is the Heir of Hufflepuff, Meghan (OFC, daughter of Sirius) is the Heir of Ravenclaw. Harry/Ginny, Ron/Hermione, Remus/Tonks.
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'.
Harry can still talk to snakes, though. As the Harry Potter series came to an end, many fans have pondered this. The solution is somewhat intricate. Albus, Harry's son, possesses the Parseltongue skill in Harry Potter and the Cursed Child, the play that continues the tale.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
Through his mother's family, he is the last descendant of the wizard Salazar Slytherin, one of the four founders of Hogwarts School of Witchcraft and Wizardry.
Salazar Slytherin was a descendant of Herpo the Foul, which is where he would have gotten his Parseltongue abilities. I believe Slytherin was the first “famous” descendant of Herpo, so he would be one of the first Parselmouths we'd know of since this ability wasn't widespread at that point in Wizarding history.
Moaning Myrtle
Born in the late 1920s to Muggle parents, Myrtle Warren started her Hogwarts life in the early 1940s, where she was sorted into Ravenclaw.
Neither of them is Slytherin's heir. Although, as Dumbledore says, Harry's ability to speak Parseltongue is a skill accidentally transferred by Slytherin's actual heir, Voldemort, when he tried to kill Harry as a baby. So perhaps this is one myth with a bit of truth to it.
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. The problem with being a female Slytherin heir, is that they're cursed.
Harry himself is a half-blood, since his pure-blood father, James, married a Muggle-born witch named Lily, and his maternal grandparents were Muggles.
He is proud
Pride is a key Slytherin trait, and arguably Albus has it in cauldrons. Sometimes this is to his advantage, like when he takes pride in having a friend like Scorpius Malfoy, who is funny and clever and kind, no matter what the rumours say about him and his parentage.

and soon gave birth to Tom Riddle Jr., otherwise known as the Dark Lord himself.
Cruciatus Curse ('Crucio')
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius.
Bellatrix Lestrange Killed her own cousin, Sirius Black: She killed Sirius (who was her cousin) during the battle at the Department of Mysteries. She was remorseless and was cackling in glee after she had murdered Sirius.
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.
Known Parselmouths
Ginny Weasley was able to speak Parseltongue while she was possessed by Tom Riddle's Diary, which enabled her to open the Chamber of Secrets.
Riddle ultimately changed his name, by way of an anagram, from "Tom Marvolo Riddle" to "I am Lord Voldemort", as a way of removing his own heritage and of exalting himself, and he killed the Riddle family, partly because they were Muggles, and partly because they abandoned him and his mother.
