Chapter 13: Quiet- Yeah, Right

Today was just another seemingly ordinary day for the Spirit World crew. Well, except for the fact that they were in Hogwarts. And the fact that Yusuke and Kuwabara's last detention with McGonagall had been done and over with last night. And the fact that today was-

"Oh, bloody HELL!"

-Valentine's Day.

"What are you 'bloody hell'-ing about now? It's a Saturday. No classes to be late for," Padma said into her pillow groggily.

"It's Valentine's Day." Thia was jerking on her sneakers, still a bit damp from taking a shower.

"Bloody HELL!" Padma snapped up immediately. "I forgot!" She scrambled around, apparently looking for something. Finally she straightened up, holding a gaudy, heart shaped box of Honeydukes' best chocolate.

"Who's that for?"

"Michael Corner."

"Wasn't he going out with Cho?"

"Hmh. One look at Suichi Minamino and it was all over. They kept it going for a while, but broke up about a month ago. Fickle girl, that one. Went out with Potter last year. And before that... well, she was going out with Cedric Diggory. But we all know about that, don't we."

"So you gave up on Suichi."

"Oh, please. You can never give up him. But apparently he's got his heart set on someone else."

"See you later, then, Padma. Have fun!" Thia waggled her eyebrows suggestively.

"You too!"

Kurama was having a hard time trying to fend off admirers.

"Um... Suichi!" he heard Thia call, and went off in the direction of her voice. "You look a little... how shall I put it?... worse for the wear."

"It's better if you don't ask. Shall we go?" Kurama looked around nervously and, seeing Thia nod, smiled.

As they made their way through the Hogwarts halls and down to the Great Hall, Thia noticed that her friend's eyes kept darting around, this way and that. It was almost as though he was expecting something or someone to pounce on them at the last moment. She was almost surprised that he didn't have his rose out, just in case.

"You look like a rabbit instead of a fox," she finally murmured to him under her breath.

"Sorry," was his sheepish reply. "It's just that Valentine's Day isn't usually a...calm...day, in my experience." Thia stifled a giggle.

At that very instant, a high-pitched shriek rang through the air.

"SOMEONE HELP!"

Thia and Kurama ran back up the steps and up towards the scream, finally leading them directly to the entrance of the Hufflepuff common room. Students were already gathered around, and neither Kurama nor Thia was able to part the sea.

Albus Dumbledore, however, was. He glided up the steps with a speed and agility no one would have dreamed a man of his age could've possessed. Instead of entering the common room, though, he called out two names: "Miss Sherwood and Mr. Minamino."

"Should we fetch the others, sir?" was Thia's worried question.

"They have already been called for. Sodsgobbins!" The mosaic marking the entrance of the dorm rearranged itself (a.n.: much like behind the Leaky Cauldron in Diagon Alley... I don't have any imagination about house doorways and I doubt all of them are paintings or stone walls) to form a doorway.

"Be safe."

The two made their way into the unfamiliar house cautiously and silently, needing the element of surprise for their attack to be successful.

"WAAHA!" something screeched, leaping into their path and reaching out its extraordinarily long fingers. Thia gave a small 'meep!' of astonishment, and leapt back a few steps.

The element of surprise went completely down the loo- at least for Kurama and Thia, that is. The demon certainly had it down pat.

"Ah, two more students! It's my lucky day!" the thing shrieked. It was hard to tell, with the short hair and the high-pitched voice, whether this was male or female. It did have sallow, greenish skin and cat-like yellow eyes, not to mention extremely long and thin limbs.

Kurama and Thia only watched him, waiting for the attack that was inevitably coming.

Six tangible slashes flew at them, one for every finger on the demon's hand. Both of the students leapt out of the way, though in different directions. The scratch marks crashed into the wall behind where they once stood, causing a large crater in the stone.

"Would someone tell me-" a boy mumbled as he walked out of the dormitory, down the stairs, and into the common room. There was a hoarse yelp of shock and fright as he saw the demon, who made a grab at him.

"Get down!!"

"Stupefy!" the Hufflepuff yelled at the top of his lungs, fumbling around with his wand. The spell hit the demon and seemed to freeze it for a moment. The key words being 'a moment'. It began to move again and grow menacingly nearer.

"Rose Whip!" Kurama said, lashing out at the demon and successfully distracting it. Thia ran to the boy.

"Listen to me. What's your name?"

"Kevin Whitby. You're in Ravenclaw, aren't you? Then why-"

"No time, Kevin. Is anyone left in your dorm?"

"Yes. Four of us. I'm the only one awake."

Thia bit her lip. "All right then. I think... I think you'll just have to stay in the dorm. It's dangerous here, me and Suichi can handle it. Don't open the door, hear me?" Like that'd ever stop the demon from getting in. "Go! Colloportus!" she said, sealing the door behind him. Kurama was still battling the demon, who was a whole lot stronger than the first three. Thia made her way to the girls' dorm.

"Don't be sneaky!" the demon commanded in a shrill voice, and spun around, fingers outstretched. It ran towards the girl and, before either Kurama or Thia could react, slashed out with its sharp claws.

Blood streamed from a cut in Thia's arm.

At least it wasn't as bad as the damage this demon was nursing. It had been cut cleanly in two by Kurama's whip.

"By the looks of it, you don't need our help," Yusuke commented as the rest of them ran in.

"What took you so long?" Thia asked, glaring at Yusuke.

"Hmm, let's see, there was one demon in the dungeons and another one in your common room that you conveniently missed, DO YOU THINK THAT COUNTS?!"

The girl laughed. "Jeez, Yusuke, you take everything so personally! I was teasing!"

"There is no time for jokes, Miss Sherwood. There are more demons in the Gryffindor common room. Hurry!" Dumbledore shooed them out. The five bolted as fast as they could to the painting of the Fat Lady.

"Hurry!" was all the Fat Lady said before swinging open on her hinges.

"Stupefy!" Hermione yelled desperately. Ron had been knocked half-way across the room and was not looking good, but Harry and Hermione stood before the five terrible demons, wands pointed at them menacingly, and trying with all their power to stun them, even though they were outnumbered.

"WOULD YOU JUST GO FOR COVER?!" Thia screamed at them, summoning up energy into her palm.

"Do we want to capture these alive?" Kuwabara asked uncertainly.

"Did you capture the other ones alive?"

"Yeah."

"Then we can kill these five."

"Kill who, kiddie? Not me!" And one of the demons, looking exactly like all of the others that had been killed or captured, slashed out.

"Damage Spheres!" The six cuts were met in mid-air by six green orbs from Thia's palm, and, after battling a moment, were absorbed and disappeared into nothingness. A slash from a certain whip demolished the monster, who, though it made a fairly good attempt at it, was unable to escape.

Meanwhile, Hiei was sheathing his katana after having beheaded the second demon.

"Dammit, shrimp, that one was mine!"

"Is that so? Your name wasn't written on it." Hiei seemed to be trying not to roll his eyes.

"Shut up, dwarf!"

"Spirit Gun!"

"URAMESHI! WHY AREN'T YOU PEOPLE LETTING ME FIGHT?!" the carrot-haired one hollered as a third demon bit the dust.

"You snooze, you lose, Kuwabara, and that's the way it goes." Yusuke smirked self-satisfactorily.

"Oh, sure. SPIRIT SWORD!" the carrot-haired warrior bellowed, and charged straight at one of the remaining demons, who cackled in delight. He wasn't laughing when Kuwabara's sword stretched out and impaled him.

The last remaining demon smirked widely, gave a mocking wave, and vanished.

"Dammit! He got away." After a moment of temporary disappointment, Yusuke grinned once more, totally satisfied at the mess that had been made of the Gryffindor common room. And then he seemed to see Harry, Hermione, and Ron for the first time. The first two of whom were oggling unabashedly at the five others.

"Who- What- How-"

"Well this blows. Our cover's gone." Kuwabara gave a quick glare at Yusuke, who asked, "What? I can't tell the truth anymore?"

"How could this happen?! No one's supposed to be able to Apparate onto or off of Hogwarts grounds! It's not possible!!!" Hermione yelled, her voice strangely high-pitched with fright.

"Nevermind that. I believe your friend needs the infirmary," Kurama pointed out, motioning to Ron.

"Oh. Right." Harry and Hermione ran to their friend and sat him up, whispering and helping him to get up.

"Nice job, guys! And girl," Yusuke quickly added.

Thia smiled a moment, then felt a wave of intense dizziness wash over her. She reached out and clutched at Kurama's shoulder to steady herself.

Concerned, he asked, "What is it?"

"Dizzy. And everything's gone an odd color." Slowly Thia let go, balanced once more.

They turned to leave, but not before Yusuke commented, "What're you doing, trying to poke your eyes out?" This he directed to Thia, who had taken her glasses off and was fingering her eyelids, almost as though she was trying to see if they were still opened.

"Oh, no. Okay, I will not panic, I will not panic," Thia mumbled, over and over to herself, not seeming to take any notice of Yusuke or the others. And then her head snapped up and she began to panic.

"Is everyone still here?" She was met with shocked silence. "Dammit, I'd like an answer!"

"Calm down, we're still here."

Another wave hit her and she fell heavily to her knees.

"Thia!" Her breaths were heavy, labored, and spaced far apart. The cut on her arm, which had stopped bleeding after the first minute or so, slowly began to trickle again.

"I would suggest you take her to the infirmary with Mr. Weasley." Albus Dumbledore once again swept into the common room, Professor McGonagall close at his heels.

"Thia, can you stand?"

"Yeah, sure. Standing sounds great," she babbled. Clumsily, she got to her feet, but taking a step proved to be too much. One arm was slung over Kurama's shoulders and one of his went around her waist, and in ths way they went down to the infirmary.

"Isn't it funny how you were right?" Thia said to Kurama, her tone strained.

"Right about what, exactly?"

"Valentine's Day... wasn't calm in the least." She made an amused sound in her throat.

"What happened?" Madam Pomfrey wanted to know, but no one knew what, exactly, to say.

"There were these things in the common rooms and they just attacked!" Hermione exclaimed abruptly.

"I suppose Mr. Weasley got in the crossfire?" Harry and Hermione nodded, and Madam Pomfrey continued with, "And what's wrong with her?"

"We don't know. She was injured earlier, but it seems as though something else is wrong." Kurama glanced again at Thia.

"What are the symptoms?" They turned expectantly to Thia, who had her arms wrapped tightly against her knees.

"Symptoms, Thia, what are they?" someone asked loudly.

"Dizzy... can't see... can't hear all that much... can't breathe... too tired to move... cold..." A feeble grin made its way onto her lips. "Sure as hell... isn't caffeine withdrawal..."

Madam Pomfrey made a disapproving noise in her throat, and then examined the five inch cut on Thia's arm. It was still trickling blood at a fast rate, but the area around it appeared to be tinged a peculiar periwinkle color. Odd, to say the least. Gently, the nurse prodded it with a finger and- to her surprise and shock- a ghastly violet liquid seemed to seep out of Thia's pores.

"All right, it's a poison, then. I'll patch her up and you all shoo. No, I don't care if she's your friend, the sooner you're out, the sooner I can heal."

Author's Notes: Aha! The Ominous Number Thirteen. I was almost going to call it Luck or Lack of It... Did you ever notice that in the HP books something happens during chapter 13? Not necessarily terrible, but something relating to one of the main villains? Weird... I hope that this doesn't count as a cliffhanger, because I didn't mean for it to be. I hope you didn't (once again) get grossed out by the description of the poisonous cut... My imagination just runs away with me sometimes. Um, okay. I might not be able to update for a few days because I'm going on vacation to a place without a phone line. NOOO! Well, my mom is going to drag me anyway, no matter how much I pout and sulk.

shadowkitsune, Slave2anime, and Mike the Great Thaaaaaanks for the reviews!!!

Rose I will admit, my brain was frying when I wrote most of Chapter 12... One of the down sides of having nothing to do but sit in front of a computer screen... or in front of a TV screen... or in front of my bookshelves contemplating which book/manga/comic to read today... Anyway... sheepish grin I always forget to put the "who-said-what" thingies before or after the quotes...

Falcon-sama MORE RAMEN!!!! YAY!!!

xKitsunex lol. I hope that Kitsune pays Meghann the M&M's! Ooh, now I want M&M's.
