Chapter 8 – Secrets
Hawthorne common room was close to the new library, as well as a passage across to the old castle. Luckily, it wasn’t far away from Gryffindor common room. A little owl statue marked the entrance, and their instructions said that they needed to do something creative to gain entrance. The most vocal Hawthorne sang a bit of a song, and the owl tapped a wing against the stone wall behind it. The stones reformed into an archway, and everyone filed in.
Jongho couldn’t believe what he was seeing once he entered. The octagonal room was much bigger than the Gryffindor common room, with tonnes of couches, tables, chairs, and other spaces to gather. There were a few different fireplaces, too, with abundant floo powder stacked beside them. The roof was a normal height, but it was covered in skylights that showed the sky above. Stars twinkled down at them. Comfy window benches with fluffy pillows lined the room, broken up by 8 different doorways.
Jongho glanced over at Hermione and saw her eyes shining for the first time that night. She might be spending a lot more time here than she thought. And it was probably a plus that Ron wouldn’t be able to follow her here, too. It definitely looked like a great space to study, or even sit and daydream.
As they walked further into the room, they saw signs explaining where the different hallways led. “Pasture,” read the closest on the right. And then next to it, “Greenhouse.”
“Seonghwa is going to have a field day if he’s got a semi-private greenhouse and pasture to work in,” Wooyoung said. Jongho snickered. Seonghwa was obsessed with plants and magical creatures, so he definitely would love this kind of thing. It would also save their secret base from turning into another jungle or pet menagerie like it had in the past.
Wait.
Hadn’t Seonghwa run to their home base carrying something? What did he have? Something that was worth a fight, and a confundus charm on the entire school? Jongho remembered that Seonghwa had immediately started a fire and tended to it. He had thought it was strange back then, but it seemed even more suspicious now. What exactly had he brought to school with him?
As if reading his thoughts, Wooyoung jabbed Jongho in the ribs and shook his head discretely. Hermione frowned at them both, but offered, “Let’s take a quick look, and then I think I’ve found an….intriguing place to explore.” She was clearly trying to make it look less suspicious, since other students were still lingering nearby.
Jongho nodded. “Sounds good! Greenhouse first? Let’s see how much space they’re giving and if it’s enough for Seonghwa’s schenanigans.”
Wooyoung chuckled. “I doubt it. It’s never enough space for his plants. The room will have to stretch to–“
He stopped mid sentence as a loud whirring sound roared into life off to the right. Everyone stopped and turned their heads towards it, wondering what was waiting for them. Was this another surprise activity? Wooyoung, Jongho, and Hermione shared a dark look and drew their wands.
“It can’t be?” Wooyoung said.
“It might be,” Jongho said.
“Let’s check,” Hermione offered, and together with many other students they all ran down the hallway for greenhouse. The whirring sound got louder, and they arrived just in time to see the room finish morphing itself into a bigger space. Green glass roof panels stretched and snapped into frames, and then the whirring noise stopped.
Students around them loosed a breath. Not a surprise activity – just a stretching room.
“Whoa. So just because I said it, it adjusted just like that,” Wooyoung said and snapped his fingers. Everyone gathered stared at the space where new tables and potting equipment popped into existence. That was impressive.
“It’s almost like the room of requirement,” Hermione whispered. Others who remembered that room nodded their heads in silent agreement.
They went back to the main part of the common room and checked out each of the hallways one-by-one. The pasture was a large room with a ceiling made entirely of glass. And in each corner, there were different mini environments – a little pond, a treed area, a gated pasture, and a rocky area filled with sand. It was a haven for different types of creatures, and no doubt it would stretch to accommodate many.
The other hallways weren’t as exciting. A place to do potion work, a place to practice charms, another to practice defence against the dark arts. Two others led towards dormitories that they weren’t able to enter. They were pushed back every time they tried to step in both of those hallways. No doubt it was for the exchange students, and to allow them some privacy as this was their only house.
The last hallway was marked “activities” and no one could enter it. Yet. Jongho wondered why they would block it off from exploration, and if that meant there was some special surprise about it, but Wooyoung said it out loud.
“They must be hiding how they’re going to keep us on our toes, huh?” He said.
Hermione nodded with a frown on her face, and curled her fingers around the edge of her shirt. She looked like she knew more than she was willing to say, but Jongho knew she likely wouldn’t when so many others were around them. Maybe she would share when it was just the three of them?
“Let’s go find that place you wanted to check out?” Jongho asked to diffuse the moment.
Hermione nodded more vigorously, and Wooyoung gave Jongho a serious look.
Jongho hadn’t forgotten that he still needed to prove his innocence. But that look brought all his burning questions back. Something had happened over the summer, and he still didn’t know what it was. Hopefully they could sort it all out tonight, although he didn’t know how they were all going to find each other. They hadn’t arranged a meeting place.
*************
Hermione led them towards the place she had picked out, and it was very out of the way. They didn’t run across anyone else, but then again: it appeared to be more of a scenic part of the castle rather than a functional one. There weren’t many classrooms in this section, and there were lots of stairs and decorative corridors. After checking her map one last time in the 5th corridor they walked down, she stopped in front of a bust statue of the late headmaster Dumbledore.
And then she twisted the map around a few times as if reading something that Jongho couldn’t see, and pulled out her wand. “Wingardium Leviosa,” she said and performed the movement the spell needed. The statue levitated for the briefest second before being pulled back into its original position as if it was attached with some kind of elastic tether. As it settled back into place, a doorway appeared behind it.
Jongho and Wooyoung looked at each other in surprise. Their maps hadn’t shown something like that, had they? Jongho realised he hadn’t really had time to check between introductions and rushing back down to get sorted. Maybe Hermione had spent the entire time checking her map instead of getting to know her new roommates? He frowned at her as she opened the door without looking back. Wooyoung was already following her in as if he hadn’t come to the same realisation.
Or if he did, he just wasn’t mentioning it.
Behind the door was a dusty classroom filled with a bunch of odd things. Desks that looked centuries old, books that seemed even older. A wardrobe filled with old robes, and an odd collection of brooms. Jongho wasn’t sure what the purpose of such a room could be, nor why it would be hidden, and just took it all in.
Hermione turned to face the two of them, and loosed a breath as Jongho closed the door behind him.
“So,” she said. “Can one of you explain why the entire school was affected by a confundus charm, and only a few of you – well, us, I suppose,” she corrected, “can remember what really happened?”
Wooyoung raised his eyebrows and looked back and forth between her and Jongho. Oh – right. Wooyoung hadn’t heard that part of their conversation at dinner.
“San sent her to us,” Jongho said, looking at his friend. “But I don’t know why.” He turned back towards Hermione. “He must have told you when we got back from the forbidden forest?”
She nodded. “He told me to act normal for now, and then said that you two would know what happened. I’ve been thinking about it for a while, now, and can’t figure out who might have done it, and why. Everything happened so fast.”
“That it did,” Wooyoung agreed. “I remember that thing heading towards us–“
“The thing that none of us could make out,” Jongho interrupted. It had been strange how the object was so big, but not something they could identify even when it got close.
“Right – which means it was enchanted somehow because there’s no other way to hide an object that big,” Wooyoung continued. “And then our friend – Seonghwa – his boat was attacked. From how his cloak was ripped to shreds, it looked like they were after…er,” he hesitated as if he had said too much. “Well, the shreds kind of look like they came from mer-folk.”
“So you think that the mer of the lake attacked us?” Hermione asked between bunched brows. It looked like she had caught his slip up, but wasn’t ready to say anything about it just yet. Jongho wondered again what Seonghwa could have been carrying.
“Well, yeah. But the ones that came after my boat once we all started defending…it looked weird. Like, they didn’t even see us – or anything. They were just attacking mindlessly. Nothing deterred them, even when my spells landed. They bounced back as if they didn’t care.”
“An unforgiveable curse?” Jongho said. He hadn’t seen the same thing in all the chaos. But leave it to Wooyoung to spot the details in a tense moment. He rarely missed things like that no matter how chaotic things got. Out of all of them, he probably saw the most tonight. San was right to send Hermione to them.
Hermione hugged her arms. “So you’re saying…whoever cursed them, might be the same person who cast the charm over the school?”
Wooyoung nodded and shrugged his shoulders. “Probably. We ran to our home base shortly after we got dropped off by Hagrid’s, so we don’t know what happened once everyone was gathered. One of our friends, Yunho, might know. He took the anti-confundus potion not long after and seemed to remember a lot. But we didn’t have time to talk after that.”
“So he got it, too. The 10 minutes. I remember him asking. So it must be after that when they cast it. But who…” she trailed off. Her eyes scanned the floor in front of her as if trying to picture the scene again. She let out a sigh. “It’s all so fuzzy. But whoever it was, they cast it sometime around then.”
“So it affected you, too?” Jongho asked.
She nodded. “It did a little bit. But I set up some, lets say, minor defences before I left home – just in case. I didn’t want to risk any pranks. I didn’t think someone would do anything truly harmful, but I also didn’t want to have an unpleasant memory from tonight should anyone decide they had something to prove.”
Jongho and Wooyoung nodded. Fame definitely had its downsides, especially when it was tied to bringing down the most powerful dark lord in recent wizarding history.
“So it must have not been strong enough to entirely break through. Although there is still a bit of a haze over things that I wish wasn’t there.” She finished.
“Maybe San can give you a bit of his anti-confundus potion,” Wooyoung offered. “He handed it to us before we went back – just in case. I’m not sure how it works, but maybe it’ll help?”
She nodded, and then said, “But even so. Why would they need to do it over the whole school…Oh,” she said and looked at Wooyoung. “You said they went after your friend’s boat. Do you know why his?”
Wooyoung shifted his feet and averted his eyes, clearly uncomfortable with the question. Jongho wondered about it, and again remembered all the times Seonghwa had smuggled creatures or plants into their home base. Could he have done the same thing tonight? But what could it be that it required a roaring fire?
Before Wooyoung could formulate an answer, though, voices popped up in the corridor.
“Awesome. An empty corridor,” Yeosang exclaimed, every sound dripping with sarcasm.
“They’ve got to be somewhere around here,” Mingi said so quietly that he was barely audible.
“There’s nothing here, Mingi. It’s just a bunch of statues. Are you sure this is right?” Seonghwa asked.
Hermione froze as if she had just been caught doing something wrong. Jongho realised she didn’t know those voices – she hadn’t met his other friends. He opened his mouth to explain and realised that he didn’t actually have an explanation for this. How had his friends found them so fast?
Another friend, Yunho, said gently, “He’s kind of right, Mingi. Could you have gotten it wrong? Maybe this is where they were five minutes ago or something.”
“Hey, I know I’m not excellent with this ability yet, but I had my arm on him most of the night,” Mingi replied, and Wooyoung ran for the door in a panic. Jongho watched him as if it was happening in slow motion. That didn’t look right – Wooyoung never panicked. “So if it brought us here, he should be here,” Mingi finished as Wooyoung pulled open the door with a force that went beyond normal.
Standing there outside the room were all their friends, wide eyed because of the sudden opening in the wall.
Jongho’s gaze found Mingi’s. He realised two things at once. One: Mingi had definitely been keeping tabs on him ever since the train platform; and two: something big must have happened that summer. Being able to find someone so fast wasn’t normal magic.
