So ‘Fantastic Beasts: The Crimes of Grindelwald’ came and went and the general consensus was that it added very little in terms of the overarching plot of the ‘Fantastic Beasts’ series and that it was essentially a filler of an instalment.

It also seemed to provide fans with more questions than answers, as Potter-heads still anxiously wait to get some clarity on some truly head-scratching plot points.

But it’s not just the Fantastic Beasts saga that boasts unanswered truths; the Harry Potter series also has plenty that  JK Rowling has avoided to this day.

Here’s 6 we had on our minds.

1. How exactly was Hagrid conceived?

The burning HP question on every fan’s mind.

Hagrid’s dad was a human wizard and his mum was a giantess. I don’t wan’t to give a speech about the birds and the bees here but the logistics of that working just seem improbable.

Probably better off unanswered.

2. What happened to Dumbledore’s father after being convicted of murder?

In case you didn’t know, one Albus Dumbledore is a pret-ty big deal in Harry Potter lore.

But considering he’s one of the most powerful wizard’s of all time, it’s odd that we know almost nothing of his backstory.

What we do know is that Percival was sent to Azkaban after murdering three Muggles who sent little Ariana insane after seeing her use her powers. He gained a reputation for hating Muggles, though we never really know if that’s the case.

It’s thought he died in prison, but apart from that, very little else.

Fill us in, JK.

3.  What happened to the real Percival Graves?

The big twist at the end of the first Fantastic Beasts film is that the head of magical security at MACUSA, Percival Graves (Colin Farrell) is actually Grindelwald (Johnny Depp) in disguise.

But what happened to the real Percy?

We don’t actually know, but either he was killed by Grindelwald or most likely locked up in Nurmengard.

There is a possibility that Grindelwald kept him alive to learn his mannerisms for his disguise, like Barty Crouch Jr did with Mad-Eye Moody, but, like we say, nobody (apart from JK Rowling herself) actually knows.

4. How big is the wizarding world and how many kids are actually at Hogwarts?

From the movies and original books, we know Hogwarts is the only wizarding school in the UK.

But in Harry’s year, at least, there really doesn’t seem to be that many students.

Is the wizarding world – or at least in the UK, anyway – really small, or is Harry’s year just the exception?

One disturbing fan theory points out a clever link between the first war against Voldemort and the number of students in Harry’s school year at Hogwarts, suggesting that there was a baby drought for a few years in the wizarding because of the high death toll.

Apparently, this is what may have led to smaller year groups.

5. What do magical kids do before they’re 11?

Not much if Ron’s early lack of wizarding-world knowledge is anything to go by.

While Muggles (like you or I) are at a certain reading, writing and maths level by the time they go to secondary school, it’s never hinted if magical children attend any sort of school before Hogwarts.

Is there some kind of magical nursery for them to attend? Or are they just left to play on brooms and do whatever they like until they get that all-important Hogwarts letter?

6. Where did the basilisk come from?

Everyone knows that a basilisk is born from a chicken’s egg hatched beneath a toad.

We know that Salazar Slytherin first created both the Chamber of Secrets and the basilisk which he used to rid Hogwarts of Muggle-born witches and wizards, but was it the same basilisk that Tom Riddle awoke over 1000 years later, or did Voldy hatch a new one.

Give us the answers, please!
