11 ‘hidden’ things in Harry Potter that prove J.K Rowling is a genius

Expecto to be shooketh

It’s a truth universally acknowledged that J.K Rowling is a literary genius. 

And Harry Potter is literary gold. 

And anyone who says otherwise is a damn traitor. 


We, like the rest of the internet, are real suckers for Harry Potter throwbacks, memes, memz and really anything Hogwarts themed (including Harry Potter-themed clothes for bubs even though we definitely do not have children). 

So when we came across this little fact on Facebook we were seriously SHOOK: 

Yeah, us: 

It got us to wondering what the inside of J.K Rowling's mind is like (we reckon it’s an exact replica of the Room of Requirement). 

What does she know that we don't?

What else did we miss????

So we compiled a list of all the genius things ‘hidden’ in the Harry Potter universe. 

Prepare your broomsticks, line up the Butterbeer shots and expecto to be shooketh. 


The Harry Potter books are set throughout the 1990s, despite being finished and published in the early naughties. 

Why the time difference, you ask? Because the dates mean something to J.K Rowling. 

Jo first published Harry Potter around 1997 in the UK and 1998 in the US. The final battle between Harry and Voldemort ends around 1997-1998, the same year Harry also completes his final year at Hogwarts. 

Hence the phrase, I open at close: the book ends the same year the actual series was first published. 


Telawney might come off as a little (a lot) bonkers but she’s not all fuzzy hair and hot air. 

She was actually the first person to sense Harry was a Horcrux. 

While speaking with Harry in 'The Goblet of Fire', Trelawney thinks she's successfully guessing his birthday when she says, "I think I am right in saying, my dear, that you were born in midwinter?" 

But Harry was actually born in mid summer, July 31. 

It’s Voldemort’s birthday that is in midwinter (December 31). So Trelawney was sensing the Horcrux INSIDE Harry when predicting his future. 


The Defence Against The Dark Arts role is cursed, we all know that. 

What you might not know is WHY. 

Tom Riddle (AKA Voldemort AKA The Dark Lord) once applied for the position but was unsuccessful. 

Bitter as ever, old pal Tom cursed the Defence Against the Dark Arts role so that no one else would hold it for more than a year.

Petty? Maybe. Pointless? Nope. 

Voldemort wanted to create a wizarding society that was ill-trained to deal with evil spells and monsters, making it easy for him to eventually take over. 


J. K. Rowling laid down hints about who Harry would end up with throughout the whole series. 

The most ‘obvious’ (we missed it, but sure) hint that Harry was going to end up with Ginny was in 'Order of the Phoenix'

Harry was banned from playing Quidditch in his fifth year at Hogwarts which meant that Ginny had to take his place as Seeker on the Gryffindor team.

Ginny won the match for Gryffindor by catching the Golden Snitch before Cho did and yes, it’s a straight up metaphor. 

J.K Rowling has confirmed that this was a clue that Ginny would also defeat Cho for Harry's affections.


Seven is very significant number throughout the whole series. 

It’s meant to, you guessed it, give a CLUE about Harry’s fate and Voldemort’s horcruxes. 

Reminder for the memory poor/fake fans: there are SEVEN horcruxes.

Tom Riddle’s Diary, Marvolo Gaunt’s Ring, Rowena Ravenclaw’s Diadem, Salazar Slytherin’s Locket, Helga Hufflepuff’s Cup, Harry Potter and Nagini

There are also seven:

  • Books (duh)
  • Years a student spends at Hogwarts
  • Floors at Hogwarts,
  • Weasley children: Bill, Charlie, Percy, Fred, George, Ron and Ginny
  • Galleons paid by Harry for his wand
  • Players in a Quidditch team
  • Obstacles leading up to the Philosopher’s Stone: 
  • Secret passages out of the school by the Marauder’s Map,
  • Golden snitches caught by Harry during his time as Seeker on the Gryffindor Quidditch team
  • Known spell types: Transfiguration, Charm, Jinx, Hex, Curse, Counter-spell, and Healing spell
  • Times when Harry Potter escaped death from Lord Voldemort before finishing him off

And that’s not even all of them. 


We love him now, but there was a long while there where we weren’t sure if Snape was a good guy or a bad guy. 

I mean, he’s a bit of an a-hole to Harry, cryptic AF, and old pal to Voldemort.  

All signs pointed to Snape being a baddie but he ultimately wasn't one, as proven by the Foe-Glass.

In 'Goblet of Fire', Dumbledore, Snape, and McGonagall enter Mad-Eye Moody's office (who is actually Barty Crouch Jr. in disguise). 

When they enter, they show up in the Foe-Glass: a mirror which is meant to show the reflection of anyone in the room who is an enemy of the owner. 

The three professors showing up in the mirror means that all three of them were enemies of Crouch Jr. And this in turn means that Snape was fighting for the good guys all along!


Dumbledore's death was inadvertently predicted by Professor Trelawney during Christmas dinner in ‘Prisoner of Azkaban’.

When Trelawney enters the Great Hall and goes to join the table for dinner, she counts 12 people already sitting down and refuses to sit down, explaining: 

”If I join the table, we shall be thirteen! Nothing could be more unlucky! Never forget that when 13 dine together, the first to rise will be the first to die!”

Phew, risk averted. 


What Trelawney (and the rest of the table) didn't realise was that 13 people were already dining. Peter Pettigrew, disguised as Scabbers the rat, was also at the table.

Dumbledore stood up to greet Trelawney when she first entered the room, making him the real "first to rise" and, later, the first to die of all the people who were at that table.


Turns out that St. Hedwig was the patron saint of orphaned and abandoned children.


The visitors entry to the Ministry of Magic is a London telephone booth. 

When taking Harry to the Ministry of Magic in 'Order of the Phoenix', Mr Weasley opens the entrance by dialling 6-2-4-4-2 on the phone. 

The passcode spells out M-A-G-I-C on telephone buttons.


Harry and Ron have a laugh while making up divinations in the ‘Goblet of Fire’.

"On Monday, I will be in danger of — er — burns," Harry says.

Then he suggests that Ron can "lose a treasured possession."

"Why don't you get stabbed in the back by someone you thought was a friend?" Ron tells Harry.

You probably thought they were just boys being boys. 

But the predictions actually come true for Harry: 

  • He’s in danger of burns during the first task of the Triwizard tournament when he faces a dragon
  • He loses a treasured possession in challenge no.2 when Ron is taken into the Great Lake 
  • And Ron ‘stabs’ Harry in the back by refusing to talk to him out of jealousy

3 from 3.  

Yes, it’s a truth universally acknowledged that J.K Rowling is a literary genius. 

And also possibly not human. 

Thanks to her, you’ll never read/watch/role play (you don’t do that?) Harry Potter in the same way again.
