Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL)

When the word werewolf abruptly popped on Felix’s mind, what had seemed to don’t make sense all of a sudden made sense.

Lupin had always brought him a strange feeling, and he thought it’s Snape’s words that had affected him. Now it did not seem so, Maybe he had captured some characteristics of the untransformed form of the werewolf, the pupils, the hair, and if anything, the aura of a dark creature.

But unfortunately, Felix didn’t think about it that way a bit.

Besides, Lupin always gave the impression of being in poor health, but when was this impression become more obvious? Around the full moon! Especially in the last two days, what with the cold not getting better, it was all an excuse … it’s the full moon a few hours before.

Madam Pomfrey’s craft is not that bad

“It’s so obvious! I can’t believe I didn’t notice the clues that were all laid out in front of me.” Felix looked at the information he had jotted down on the parchment and compared it line by line–

‘Lupin is poor because he has no decent job at all, and in order to conceal his identity, he has to be prepared to move around and change his identity all the time.’

‘He must have very rich experience in disguise, but once is by chance, twice is by coincidence, what about three or more times? For a werewolf, the abnormality will be discovered by those around him in a few months, because no amount of excuses can change the fact that a werewolf must disappear at the full moon!’

‘He had ill feelings towards Minister of Magic Fudge, who had not been in office for a couple of years because Fudge had presided over an amendment to the werewolf registration bill – he had tied the werewolf registration list to the wolfsbane potion, and without registration, he couldn’t buy the potion. This also explains why Lupin came to Hogwarts this year; as he couldn’t get this potion that keeps him sane during full-moon transformations from anywhere else.’

You know, the werewolf transformation is extremely exhausting, before there is no wolfsbane potion, and they will frantically attack anyone they see, even if they are locked in a cage, they will be so frenzied that they will lose their minds while smacking and tearing the obstacles in front of them.

The after-effects of such behaviour are intense and often last three to four days, or even a week of exhaustion, depending on one’s physique.

With the wolfsbane potion, werewolves are much more comfortable, they can keep their sanity during the full moon, find a hidden place to hide, and the next day when everything goes back to normal – a little tired at best, as well as able to brace themselves without being noticed. It’s a thousand times better than being recognized as a werewolf.

Felix remembered that two weeks before the start of school, Snape was called in advance by Dumbledore, he moodily murmured that he needed to brew a batch of ‘disgusting’ potions, other than wolfsbane potion, is there any other possibility?

Felix couldn’t help but raise the corner of his mouth, it’s hard to imagine the scene where Snape is being pressured by Dumbledore and brewing a potion for someone he hates.

‘Severus’ expression must have been funny!

There are also some other small details worth noting.

For example, Snape had said to him, “Lupin’s true face will surprise you”, supposedly hinting at his werewolf identity

Before the opening dinner, Professor McGonagall deliberately avoided Snape when introducing Lupin, which means that Professor McGonagall knew about the conflict between them, in other words, she also knew about Lupin’s werewolf identity.

Who else knew besides them?

Dumbledore is bound to know, even …

Felix calculated when Lupin went to school, Dumbledore would have been the headmaster, he was able to come to school, certainly with the consent of the headmaster.

Even the whole thing was probably promoted single-handedly by Dumbledore, who might have persuaded him personally to come to the school by visiting his family…

To accept a werewolf young wizard to Hogwarts for schooling, it is inevitable that he must be prepared a series of protective measures – including the location for werewolf transformation, as well as the care and treatment after the transformation.

For the former, Felix simply has no clue, theoretically, randomly choosing an abandoned classroom would be fine, with Dumbledore’s ability to cast all sorts of wards to isolate the howls made by the young Lupin during his transformation.

‘Hagrid once said that many werewolves were rejected by the entire wizarding community, disheartened, and preferred to live with the pack, but for young Lupin, it is unlikely that he made that choice. The biggest kind of possibility is that his parents locked him in the house and used a Muffliato Charm to keep the neighbours from hearing him …’

”Thinking about it this way, Lupin probably would have a huge psychological shadow about the Muffliato Charm?”

As for the latter, Lupin himself had admitted that Madam Pomfrey had helped him a lot when he was in school.

Felix suddenly thought of an interesting question, Harry’s father – James Potter, as well as Sirius Black and Peter Pettigrew, did they know about Lupin’s werewolf identity?

‘Should know,’ Felix guessed silently, ‘otherwise Lupin wouldn’t miss that time so much.’ He thought of the smile that radiated from Lupin’s face when he introduced his experience of going to school, and his eyes seemed to be glowing.

This raised more questions in Felix’s mind, not about Lupin, but about Sirius Black.

From the information he had pieced together, there is a clear sense of alienation in that man’s behaviour, a feeling that even reached the level of perversity.

As a teenager, Black was a righteous Gryffindor, strongly repulsed of Slytherin, and even his own family, although judging by some prohibition records Felix had seen, the man was a tad brainless …

After graduation, Black joined the Order of the Phoenix and almost immediately became a backbone in the fight against Voldemort and his army of Death Eaters, and from that point of view, he was a fearless warrior.

‘At what point did Black start to change? Was it the inability to fight against the kinship, did he get invited by his Death Eater relatives, or was he captured by Voldemort in one of his actions, and threatened with death and his family? Or just simply could not bear the torture of the Cruciatus Curse?’

”Could this be the case? After tasting the pain, it went from bravery to cowardice …’

Felix suddenly got in a bad mood, and if things went as he thought they would, he hated the story.

Especially when he saw the Longbottom couple was completely tortured by the Death Eaters to crazy, but they did not reveal half of the information, this strong contrast has made him conflicted to the extreme.

If this happened to him, how will he choose? Will he for some reason betray his best friend?

“The hypothesis is not valid at all,” he grunted after thinking for half a day.

Felix suddenly realized that he never made a close friend during his school years, the first three years were busy studying and fighting, in the fourth year he completely ignored everything around him in order to practice his spells, and by the end of the fifth year, everyone looked at him with awe.

”Speaking of which, a few Slytherin girls gave me chocolate during my school years right?, but I suspected there was a curse and threw it away.”

”Did I somehow miss something?”

Felix chewed on his former experience, after a while, he laughed dumbly.

“I’m really bored enough, but … Sirius Black, whether it’s for the collection of books in Black’s old mansion or to confirm whether you’re harbouring a vile means, I’ll give you a chance to explain.”
