LONDON — Harry Potter really is the gift that keeps on giving.

The final book in the J.K. Rowling's series may have been published back in 2007, but that hasn't stopped her from dropping a whole bunch of new revelations in the intervening years.

With Harry Potter and the Cursed Child mere weeks away, now seems like a good time to re-visit some of the secrets Rowling has disclosed since the books finished...

1. Dumbledore's sexuality.

Rowling revealed the sexuality of everyone's favourite magical headmaster during a book tour in 2007. When a fan asked about Dumbledore's love life, Rowling replied: "Dumbledore is gay."

She went on to confirm he'd been in love with Grindelwald, and was "horribly, terribly let down" by what Grindelwald ultimately became.

In March 2015, Rowling took to Twitter to respond to a fan who asked her about Dumbledore's sexuality, writing "I can't see him that way."

2. Dumbledore's feelings towards Newt Scamander.

@jk_rowling I wonder, what makes Albus Dumbledore so fond of Mr. Scamander?



i felt the need to ask you — kit (@patronuspanther) April 11, 2016

Albus Dumbledore is fond of Newt Scamander for the same reasons that I am fond of Newt Scamander. You're welcome. https://t.co/bNdwX6Tf40 — J.K. Rowling (@jk_rowling) April 11, 2016

@jk_rowling but we also know that Dumbledore has come to defend him. So, was the expulsion revoked? :) — Potterish (@potterish) April 11, 2016

Dumbledore was a young teacher at the time Newt was expelled. He wasn't able to revoke expulsions. https://t.co/UskHwSQvtJ — J.K. Rowling (@jk_rowling) April 11, 2016

3. What Dumbledore really saw in the Mirror of Erised.

In an online Q & A with readers after the release of the Deathly Hallows, Rowling responded to a fan's question about what Dumbledore saw in the Mirror of Erised.

"He saw his family alive, whole and happy," Rowling responded. "Ariana, Percival and Kendra all returned to him, and Aberforth reconciled to him."

4. James Potter and Teddy Lupin's Hogwarts Houses.

Have just heard that James S Potter has been Sorted (to nobody's surprise) into Gryffindor. Teddy Lupin (Head Boy, Hufflepuff) disappointed. — J.K. Rowling (@jk_rowling) September 1, 2015

5. The complexities of wandless magic and broomless flight.

.@bluesrgt Yes, nearly all wizards use wands, which makes magic easier to channel. Wandless magic is sophisticated and takes more talent. — J.K. Rowling (@jk_rowling) March 8, 2016

.@o0MRG0o Yes, most wizards produce more precise magic by using the correct wand, which is why they've been widely adopted. — J.K. Rowling (@jk_rowling) March 8, 2016

.@dwmw24601 @bluesrgt Exactly. Wands and brooms (and flying cars) are tools that channel magic. The most gifted can dispense with them. — J.K. Rowling (@jk_rowling) March 8, 2016

6. We've been pronouncing Voldemort wrong.

@Universe_Box One piece of Harry Potter trivia I always forget to mention: the "t" is silent in Voldemort, according to @jk_rowling. — Michael Lucero (@mhenrylucero) September 9, 2015

... but I'm pretty sure I'm the only person who pronounces it that way. https://t.co/HxhJ5XY5HP — J.K. Rowling (@jk_rowling) September 9, 2015

7. Harry, Ron and Hermione all went on to have key Ministry roles.

We'll be finding out more about what this lot are up to in the 'Cursed Child'. Image: warner bros.

Our heroic trio all went on to work at the Ministry in some capacity after leaving Hogwarts: Harry as an auror, Ron (briefly) as an auror and Hermione in the Department of Magical Law Enforcement.

"Harry, Ron, Hermione, Ginny et al would of course play a significant part in the re-building of wizarding society through their future careers," Rowling said in a Bloomsbury Q & A back in 2007.

8. Her reasons for killing off Remus Lupin.

Once again, it's the anniversary of the Battle of Hogwarts so, as promised, I shall apologise for a death. This year: Remus Lupin. — J.K. Rowling (@jk_rowling) May 2, 2016

In the interests of total honesty I'd also like to confess that I didn't decide to kill Lupin until I wrote Order if the Phoenix. — J.K. Rowling (@jk_rowling) May 2, 2016

Arthur lived, so Lupin had to die. I'm sorry. I didn't enjoy doing it. The only time my editor ever saw me cry was over the fate of Teddy. 😢 — J.K. Rowling (@jk_rowling) May 2, 2016

9. Hogwarts is free.

@emmalineonline1 @micnews There's no tuition fee! The Ministry of Magic covers the cost of all magical education! — J.K. Rowling (@jk_rowling) July 17, 2015

10. There are eleven wizarding schools world-wide.

We’re excited to announce Ilvermorny is the name of the North #American wizarding school! https://t.co/wZOnSwczyW pic.twitter.com/YvjFjSVz7b — Pottermore (@pottermore) January 30, 2016

In a post on Pottermore, J. K. Rowling revealed that there are, "eleven long-established and prestigious wizarding schools worldwide, all of which are registered with the International Confederation of Wizards."

She went on to release more details about individual schools in Japan, Africa, Brazil and North America.

11. North America has a dark magical history.

Rowling wrote about magical segregation in her four-part series of the history of North American magic.

12. Her favourite character.

@jk_rowling Besides Harry, who is your favorite character in the series? — Adam Mahan (@mahanadam) April 11, 2016

13. Hagrid and the Patronus spell.

Jo always asked you this. What was Hagrids Patronus @jk_rowling — Tanisha Fagwani (@tanishafagwani) August 21, 2015

Hagrid couldn't produce a Patronus. It's a very difficult spell. https://t.co/TRDVNvSEdR — J.K. Rowling (@jk_rowling) August 21, 2015

14. Why Harry named his son after Snape.

@jk_rowling Why did you pick Snape to name Harry's kid after? I'm genuinely curious as he was nothing but abusive towards everyone. — △⃒⃘Jasmine△⃒⃘ (@FrazzyJazzy7) November 27, 2015

Snape died for Harry out of love for Lily. Harry paid him tribute in forgiveness and gratitude. https://t.co/MPXBgUApa3 — J.K. Rowling (@jk_rowling) November 27, 2015

15. Why Snape died.

Snape didn't die for 'ideals'. He died in an attempt to expiate his own guilt. He could have broken cover at any time to save himself 1/2 — J.K. Rowling (@jk_rowling) November 27, 2015

but he chose not to tell Voldemort that the latter was making a fatal error in targeting Harry. Snape's silence ensured Harry's victory. 2/2 — J.K. Rowling (@jk_rowling) November 27, 2015

16. What she thinks about Snape as a character.

This morning I've been thinking a lot about the appeal of simple dichotomies in our messy world, then you raise Snape! Highly appropriate. — J.K. Rowling (@jk_rowling) November 27, 2015

Snape is all grey. You can't make him a saint: he was vindictive & bullying. You can't make him a devil: he died to save the wizarding world — J.K. Rowling (@jk_rowling) November 27, 2015

17. Finally (and perhaps most importantly), what Harry was hoping to achieve when he named his son after Snape.

In honouring Snape, Harry hoped in his heart that he too would be forgiven. The deaths at the Battle of Hogwarts would haunt Harry forever. — J.K. Rowling (@jk_rowling) November 27, 2015

We have a feeling that this will be key for the upcoming play — especially the final line. We know from the Cursed Child synopsis that the past will come back to haunt Harry. Maybe his guilt over what happened during his school years will be a theme in the Cursed Child.
