Harry lands in Knockturn Alley in Chamber of Secrets, when accidentally saying (in the film version) "Diagonally" instead of Diagon Alley while using Floo Powder to get to Diagon Alley.
Because when using Floo Powder you need to say where you are going very clearly. Harry tried speaking the words "Diagon Alley" with a mouth full of ashes. Instead he said “diagonally”.
Ron grabs a handful of powder, throws it into the fireplace, says, "Diagon Alley," is engulfed by green flames, and disappears. Nothing terrifying about that, right? But, of course, Harry gets all nervous and tongued tied and instead of saying, "Diagon Alley," he says, "diagonally." Awkward.
Harry Potter first travelled via the Floo Network in 1992 when he journeyed from The Burrow to London. However, instead of saying "Diagon Alley", Harry was nervous and said "diagonally". Therefore he accidentally ended up at Borgin and Burkes in Knockturn Alley.
The words "Diagon" and "Alley" when pronounced together, produce the word "diagonally" which is most probably the origin of the name "Diagon Alley". When Harry mispronounced the name due to inhaling a mouthful of ash, he landed in a fireplace in nearby Knockturn Alley.
“Welcome,” said Hagrid, “to Diagon Alley.” He grinned at Harry's amazement. “Cauldrons – All Sizes – Copper, Brass, Pewter, Silver – Self-Stirring – Collapsible,” said a sign hanging over them. Harry wished he had about eight more eyes.
Every time Harry is confronted with a Dementor, he hears the screams of his mother as she is murdered by Lord Voldemort. A horrific memory to hear... He hears this moment because Dementors feed upon happiness and cause depression and despair in anyone near them. They make people relive their worst memories.
Hagrid, who was getting Flesh-Eating Slug Repellent in Knockturn Alley, told Harry that he shouldn't be hanging around in such a "dodgy place". Hagrid then escorted Harry back to the Weasleys in Diagon Alley.
Harry, not wanting to be seen, hides in a cabinet and ends up overhearing a conversation between the shop owner and Lucius Malfoy, who has just entered with his son Draco.
"Wit beyond measure is man's greatest treasure." "After all, to the well-organized mind, death is but the next great adventure." "If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals.” "I'm hoping to do some good in the world!"
'Nothing happened,' 'Harry looked around,' 'Harry stared,' were among the sentences most used by J.K. Rowling in the Harry Potter books.
The most common phrase in the Harry Potter book series was “Nothing happened.” In the Twilight series, it was “I sighed”.
Though it would seem Prince Harry would be after his big brother, he was bumped back following the birth of William and Princess Kate's children. When Kate and William welcomed their first child, Prince George, in July 2013, the little one took the spot above his uncle.
But now J.K. Rowling, the author behind the global phenomenon, has all but confirmed that Shambles was not the inspiration behind Diagon Alley in her books.
Knockturn Alley is a shopping area off Diagon Alley in London. It is filled with shops devoted to the Dark Arts,, including Borgin and Burkes, which specialises in objects that have curious and strong magical properties. Usually, unusual and dangerous people walk around there.
After Hagrid was accused of opening the Chamber of Secrets, he was expelled and forbidden to do magic.
So in the course of The Chamber of Secrets, we learn that Hagrid was framed by a young Tom Riddle for opening the Chamber, resulting in Hagrid's expulsion and subsequent keeping on as groundskeeper. Some 50-odd years later, Tom (now Voldemort) attacks Hogwarts and takes Hagrid captive.
It is revealed during the series that Hagrid attended Hogwarts while Tom Riddle was also a student at the school, and that Hagrid was expelled during his third year (because Riddle, in his pre-Lord Voldemort days, framed him for opening the Chamber of Secrets).
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
While Dumbledore was a depressing death for Harry Potter to face as his only real father figure, the death of Sirius Black hit him the hardest.
'Remember my last'
Petunia's disdain for Harry was most likely born from a long-standing jealousy of her magical sister, Lily. A Howler from Dumbledore, addressed to Petunia, said 'Remember my last' – no doubt referring to the letter which he left with baby Harry, on the doorstep of Privet Drive.
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.
Alyssienna Symphonia Rowena Narcissa "Allie" Malfoy is the second child and only daughter of Lucius and Narcissa Malfoy, and the AquaMagenta twin sister of Draco Malfoy.
NeokratosRed used their majorly impressive mathematical skills to calculate that there's a minimum of 50,625 galleons in Harry's vault. Since we know one galleon is equal to around $25, the minimum amount of money in Harry's vault is a mind-blowing $1,265,625!
