21 Harry Potter facts that J.K. Rowling revealed years after the books were released


Yes, Rowling certainly revealed a lot of new information since the release of her books, and funnily enough – whether people like it or not – they’re still lapping it up joyfully.

Marriage counseling

Whether you’re someone who read the books, or only watched the movies, one of the sweetest things to follow in the Harry Potter universe was the romance between Ron and Hermione. Their relationship certainly had its ups and downs, but they ultimately got married. That should’ve been how the story ended, except years later JK Rowling revealed that she regretted putting Ron and Hermione together. She said she only did it as a form of “wish fulfillment,” and that she believes that the couple would’ve needed marriage counseling.

Hermione’s appearance

After years and years of watching Harry Potter films where Hermione was portrayed by the lovely Emma Watson, it was settled into people’s minds that this was what she looked like. But when the play of Harry Potter and the Cursed Child came to stage in 2016, they cast Hermione as black. This confused some people, but JK Rowling maintained that she never specified the skin color of Hermione in the books – still, you can understand why people may have been surprised.

How Harry is so rich

One of the underlying themes of the book is that Harry has got money, and lots of it – but where did it come from? We know he inherited it, but his parents weren’t that old when they passed on, so who was the real breadwinner? It turns out that it was Harry’s grandfather, an inventor named Fleamont. Rowling revealed that he was the inventor of Sleekeazy’s Hair Potion, a successful product that he’d eventually sell for a large fortune.

Parental discrimination

Hey, remember Draco Malfoy? You know, that kid who always got on Harry’s nerves at school, and eventually became a Death Eater too? Well, he ended up coming back to the “good side” and married a girl named Astoria Greengrass – but it was later said by Rowling that Draco’s parents did not approve of her, because she didn’t come from one of the “sacred 28 pure blood” families. Discrimination is a prevalent theme in Harry Potter, and it’s nice to see that Draco finally stood up to his parents.

Dumbledore’s true colors

There were many things that JK Rowling revealed about characters from Harry Potter after the books were published, but perhaps the thing that shocked people the most was when she said that Albus Dumbledore was in fact a member of the LGBT community. As if to defend herself, she maintained that when Dumbledore was younger, he and fellow powerful wizard Gellert Grindelwald had a relationship that may have a strayed into areas that were more than friendly – but, of course, we know how that ended.

Emotional sorting ceremony

When a student first comes to Hogwarts, the first thing that happens is that he gets sorted into a house – Gryffindor, Hufflepuff, Ravenclaw, or Slytherin. And people tend to get pretty intense about who gets sorted into where. Rowling revealed on Twitter that when Harry’s son, James, first came to Hogwarts, he got sorted into Gryffindor, and that Teddy Lupin, godson of Harry, son of Remus Lupin and Nymphadora Tonks, and Head Boy of Hufflepuff, was slightly saddened by it.

Jewish wizards?

People tend to call out JK Rowling on Twitter when something is bothering them about Harry Potter, and sometimes, she responds. After a Twitter user asked JK Rowling why there were no jews at Hogwarts, she had her answer ready faster than anyone expected: “Anthony Goldstein, Ravenclaw, Jewish wizard.” Well, how about that – perhaps there was a jew at Hogwarts – we only wonder if he lit his Chanukah candles with matches or by magic.


For those of you that really know your Harry Potter knowledge, you know that Neville Longbottom, one of the most dynamic characters in the book, had heroic parents who suffered a terrible fate. Frank and Alice Longbottom were tortured by Death Eaters when he was only a small child, and although they didn’t die, they were permanently hospitalized. But when fans expressed hope that they would one day get healed, Rowling refuted this, saying that they, sadly, would never leave the hospital.

Modern day Longbottoms

Yes, the fate of what happened to Frank and Alice Longbottom, Neville’s parents, was truly sad – but this may cheer you up. Another thing that JK Rowling revealed after the books were released was that Neville, a boy who quite often had trouble with schoolwork, would eventually became a Herbology professor at Hogwarts – which makes sense, considering it was his favorite subject. She also revealed that he married Hufflepuff Hannah Abbott, who became the landlady of the Leaky Cauldron.

Back to school?

After Harry finishes his sixth year at Hogwarts, he, Ron, and Hermione, drop out of school to hunt down Voldemort’s horcruxes – a mission that they’d ultimately succeed at doing. Once they were done, they didn’t really feel the need to return to Hogwarts. Hermione however, felt differently – Voldemort or no Voldemort, she was going to graduate from Hogwarts, and that is exactly what she eventually did. JK Rowling really did put a lot of thought into their lives after Hogwarts, didn’t she?

I can see you

There is an item in the book that turns up on numerous occasions, and that of course, is Harry’s invisibility cloak, which was passed all the way down to him from his ancestor, Ignotus Peverell. But while it is considered to be an extremely ancient and rare magical object, there was always speculation that a certain someone could see through the cloak – and that someone was, of course, Albus Dumbledore – a fact that Rowling later confirmed to be true.

A silent “T”

Are you ready for this? Say the word “Voldemort.” Now, did you pronounce the “T” at the end? Good, so did we, and so did the rest of the world for the last two decades. But apparently, JK Rowling decided to let the world know that we’ve been pronouncing it wrong this whole time. She said that when she originally wrote the book, the “T” at the end had always been intended to be silent. You’re a bit late on that memo, JK.

Hogwarts tuition

There was an intense Twitter debate about the financial aspects of Hogwarts that needed to be settled by the creator herself. A Twitter user asked JK Rowling what the cost of the Hogwarts tuition was, and Rowling had her answer ready – would you expect anything less? She responded that Hogwarts tuition is free, and that the Ministry of Magic covers the cost of all magical education? Ummm, what? Now you decide to tell us this? Why does it feel like she made that up on the spot?

Big trio career paths

As we know, the events of the battle of Hogwarts resulted in Harry, Ron, and Hermione being hailed as the young rising leaders of the new magical establishment, especially since they’d helped defeat the evil Lord Voldemort. This type of recognition allowed them get pretty much whichever job they wanted, Hermione getting a job in the Department of Magical Law Enforcement, and Harry and Ron becoming aurors (Although Rowling additionally revealed that Ron would leave the auror office to help George run the joke shop).

What Dumbledore sees

In the first installment of the Harry Potter series (Sorcerer’s Stone), there is a device called the Mirror of Erised, something that shows the person who looks into it, their heart’s deepest desire. Harry saw his parents when he looked into it, but when he asks Dumbledore what he sees, Dumbledore gives him a false answer. After the books were released, Rowling decided to tell fans what the real answer was: “He saw his family alive, whole and happy.”

Chocolate frog legends

One of the most iconic scenes of Harry Potter is when Harry first meets Ron on the Hogwarts Express in their first year, and they proceed to fawn over chocolate frog cards. This is especially poetic when you consider that years later, both of their faces would eventually shine out from future chocolate frog cards as well, along with Hermione’s too. JK Rowling revealed these facts, along with the notion that Ron would consider it his “finest hour.”

Other wizarding schools

What were about to reference now is not just something that JK Rowling “revealed” – it’s something that opened up an entire new world that raises about a thousand more questions that we never had before. For a long time, most people never considered how many wizarding schools there were. But since the Harry Potter series was released, Rowling revealed that there were “eleven long-established and prestigious wizarding schools worldwide”, and one of them is Ilvermorny, in North America.

No patronus Hagrid

Everyone loves Hagrid, and there are many reasons for that. He’s kind, caring, and loves animals – but according to JK Rowling, he was not that good at magic. We know that he had his wand confiscated while he was in school, so we don’t really have a chance to see him perform a lot of magic (his pink umbrella sure is interesting), but Rowling assures us that Hagrid actually was never even able to cast his own Patronus.

Wandless magic

There is a certain aspect of magic that got lost somewhere in the translation when most of us read Harry Potter – or at least, that’s Rowling would have us believe, years later. While pretty much all of the characters, including Voldemort himself, set so much store by using wands, Rowling revealed that in the world of Harry Potter, using wands isn’t by any means required to transmit magic. That said, she concluded that while wands aren’t necessary, they allow the witch or wizard more control over their magic.

Professional Quidditch star

One of the most underrated aspects about the fact that Ginny ended up with Harry is that they are a lot more alike than we give them credit for. For instance, Harry and Ginny were both on the Gryffindor Quidditch team, but according to Rowling, Ginny was such a talented player that she eventually played professionally for the Holyhead Harpies. That said, she eventually retired to be senior Quidditch correspondent at the Daily Prophet, and settle down with Harry and their three kids.
