Wilson nodded after every piece of information he would receive from either Angus or the children. The story was becoming more and more interesting with each sentence, and although he had hoped that he would never again have to think this way, his mind was already prepared for battle. Certainly, the level of threat that these thugs posed wasn't nearly as grave as the ones Khaat, Robert, Jess, and the others had faced years ago - they seemed to lack the logistics for a more grandeur plan, at least at this point in time - but he was also aware that this wasn't a simple protection task. There was much more to it, as he would soon find out during the conversation, and that is what both intrigued him and scared him. How could these people have gone unnoticed? How could they have had the background to penetrate Hogwarts' defences? It was a mystery, but a mystery he would definitely solve sooner rather than later. ''I've considered Polyjuice Potion myself, but that would require something belonging to the Alchemy Professor, but I do not think they've entered the castle; if they had, they would definitely have been stupid to have come up with such a complex plan instead of just taking the children from inside the castle and leaving. No, I do not think it was Polyjuice Potion, plus, as the boys said, the Hag seems to have transformed immediately then they reached their destination, and Polyjuice Potion, while it has a limit, doesn't work like a clock. It would have been too convenient had the effect worn off at that exact moment'', Wilson remarked, still mulling the whole thing over. ''I do know of some spells that can transform someone's appearance, but this was too detailed, too refined. That is why I asked whether their mother was a skilled witch. This definitely means that she had some help and that there is someone else whose interests are aligned with hers in this. Be that as it may, such spells are really complex and only exceptionally talented wizards and those who are skilled with Transfiguration are able to use them this effectively. Personally, I know only a handful of people, myself included, who could do such a thing and while some underground bloke might have slipped my radar, I am doubtful that they... whoever they are... would have such a powerful wizard or witch with them. A magical object, something that creates an illusion, would make complete sense, as you have suggested it, Mr. Donohue. These things come in all shapes and sizes and if you know how to create one illusion, the rest is simply tweaking it to get the desired result and an engineer would probably have no trouble doing it. It could also account for the fact that the 'Professor' appeared in the classroom unnoticed... the real professor might have gone to her office and would not have noticed an impostor, whereas the children would not suspect anything because the real professor could've simply returned to the classroom. They say that the best way to go unnoticed is to do something when everyone can see you. This seems like such a situation. If it really was a device, if I had any piece of it or part of the Hag, I could probably identify what it was, but as things stand now... it is going to remain a mystery for the time being. But, that won't be an issue, not a major one, at least. We have a general idea of how they did it, and that definitely helps'', he finally explained. ''And yes... I do understand your position, Mr. Donohue. Sometimes... you just have to do the proper thing, however deplorable it might be'', Wilson added with a somewhat sympathetic smile, the best he could do, as he did not really know how to smile; the Fiendfyre was, once more, flying in his eyes.
The boys then had another emotional outburst related to their mother, and that brought him back rather quickly. It was obvious that their family history was a troubled one, but from what Wilson could see, the two boys grew up to be healthy young adults that knew how to discern right from wrong, even if the wrong was their own mother. He supposed that Mr. Donohue and their sister, whom they had mentioned earlier, helped with that, but it was still an admirable feat to raise anyone under such conditions, which is why them being so sincere and righteous was even more important. But, then again, Khaat and Robert certainly would not have trusted just about anyone, so their trust in Angus was a guarantee to Wilson that he was dealing with someone whom he could trust and who would definitely take care of the boys in a proper way.
The topic then switched to the more grim part of the story, a direction Wilson had hoped it would not take, but subconsciously knew it would. He, of course, knew of James Blood, and he somehow thought that the psychotic villain would not appear back in his life after so many years, but it seemed that he was definitely a remnant that kept on returning, although no one wanted him back. James Blood had to be taken care of, he was far too dangerous to simply ignore, but from what Angus said, there was an even more pressing matter in front of them. Wilson had heard the name Gelding a couple of times, but he did not really bother much with it. He knew they were criminals, but since, at the time, the Order and his friends and allies had more pressing matters, the underground dealings of everyday criminals, however atrocious they might have been, simply never came into the spotlight. But now, with a little piece here and there, it seemed to Wilson that the time was ripe to do good with those that they had, sadly, left to care for themselves at the time.
''I do remember James Blood... yes. He was someone that I... well... not just me, all of us, simply did not manage to catch. I do not know how much you know about me and my actions in the past, but aside from my academic travels, I have always been an active member of the now-disbanded Order of the Phoenix; that is actually how the Lupins and me became so close. And I do imagine you'd not consider a simple professor being interested in such issues, but Khaat has informed you well by telling you that this is definitely something that interests me. This world has too much darkness in it and while we cannot eliminate it permanently, we can do our best to stop it from spreading'', he replied. He smiled as Angus gave him the (port)key; it was just like the Lupins to come up with such a joke, and it was just like Robert to prepare everything beforehand. Wilson took the (port)key carefully and placed it on the desk, in a lone corner where no one would really come into contact with it. ''I trust Robert has already anticipated my answer, which is just typical him, I suppose. I haven't seen him in a long time, it will be nice to catch up on things. Please inform him that I shall visit today, probably later in the evening, as I still have some classes later today. And tell him I shall bring an umbrella'', he remarked.
He then turned to the boys, who were eagerly listening to the whole conversations. They felt important, and it was sweet in a way. They knew they were the victims here, but they participated in this conversation with such vigour and concentration that you'd never tell they needed any protection. ''Now to get back to you two.'', he said and smiled, again, the best he could, ''You mentioned that you were not able to find the Moonstar Mallow in a Herbology book? I suppose you wouldn't find it there because it doesn't actually exist... but...'', he stopped, flicked his hand and a large book appeared flew over to the desk and opened itself to a certain page. It was an old book on dark creatures and beasts, a book he had bought while he was traveling in Eastern Europe some years ago. It was horribly outdated and unusable in class, but it was a source of numerous fringe information and Wilson considered it, despite a lot of the data from the book being mere fairy tales, a valuable resource for some of the more obscure aspects related to the creatures he taught about. The chapter that the book opened to was about werewolves, and while Wilson was aware that the children would not understand the Russian text, there was an illustration of a silver-blue flower at the bottom of one of the pages. ''The Moonstar Mallow'', he pointed at the sketch with his hand. ''The Moonstar Mallow does not exist, of course, it never has, but it is related to an old legend from Eastern European folklore that one could either become a werewolf or stop being one by means of that specific flower. You had to prepare a potion and do a ritual, and based on how you brewed the potion and how you performed the ritual, you could either become a werewolf, or you could cure yourself of being one. I have tried to find any record of the flower's existence save for this book, but all the Russian wizards and warlocks, some of which were very old werewolves, confirmed to me that it was a centuries-old legend that some Herbologist came up with to earn some money by supposedly 'helping' people become what they wanted. No werewolf will actually tell you that it exists, and the fact that the Hag was told to use this legend as a way to lure you speaks for itself. First of all, the flower, according to this book, bloomed only in the mountain forests of Siberia, the Ural Mountains and the Caucasus, and it was exceptionally hard to find as it supposedly bloomed only when the Moon was full and died instantly the next morning. It had to be picked by then, or else it was completely useless. Of course, conveniently, it also grew among other similarly-looking flowers, which is why people usually missed it. That was, of course, just a hoax, but it is a known legend among the werewolf communities, which definitely proves that our theories about the connection between your mother and James Blood are correct'', Wilson explained as thoroughly as he could and then turned briefly to Angus. ''This is far more grim than I had suspected it could be, Mr. Donohue. This is a serious matter that we have to attend to immediately. My office is, luckily, in one of the towers, so you can, of course, always send Archangel my way. I trust he already knows his way to my old office, and he has always been properly taken care of. I definitely agree that it is a very trustworthy way of communication, and I implore you to use it whenever you need it. Do not hesitate contacting me under any circumstances'', he said, and then looked back at the boys.
''Well, knowing Revelio is not such a big thing for a graduate, is it?'', he remarked and gave them a puzzling look. ''But knowing how to use Revelio without saying the incantation is a thing of interest for you. Since this is a confidential matter, I cannot really send you to the Charms professor, as it would raise too many questions. This means that I shall have to teach you how to use Revelio non-verbally, and we shall start our lessons on Monday, seven in the afternoon. We'll be doing these lessons until you have mastered it. I am fairly certain that they won't see it coming, they won't expect it, which gives you two a tactical advantage. You did say that you would not fall for the same trick again, but I somehow doubt that the mastermind behind such a complex scheme would repeat now that he has attracted attention with it. But, I somehow doubt that they could anticipate you knowing this, as it is not that commonplace. Since you seem to be coming in pairs, one can always simply hide their wand and use the spell non-verbally to see whether anything's amiss. Revelio is useful in that aspect, as it can breach even the best spells and potions. That way, you will always be certain about your surroundings. I trust this is fine with you boys?'', he asked and then turned to Angus, ''And you, too, Mr. Donohue?''
