A/N: I don't own HP or House, and please review!

And so it was, at ten to midnight, that Doctors Chase and Foreman slipped into the heart of nighttime Hogwarts—complete with moving staircases, ghosts, talking portraits, and a very grumpy caretaker.

"Chase," hissed Foreman as the two made their way past the third floor corridor which had once housed a three-headed dog named Fluffy. "Come on…I think that the dorm is this way."

"No—that knight picture said that Harry Potter's old 'house' was up a few floors, not down!" argued Chase, squinting through the pitch dark.

"Shut up!"

"No! I am positive that it was in a tower, not the dungeons!"

"No, I mean somebody's coming!" Chase's eyes widened as Foreman grabbed him and they both shrank into the shadows. They watched with trepidation as a shadow slunk into the corridor.

"It's a cat," said Foreman, letting out a breath as the cat took in their appearance appraisingly before yowling loudly.

"Uh…I'm not so sure that's a good thing right now. Let's get out of here."

"Good idea," agreed Foreman. With that, the two stood up again and tip-toed to the nearest staircase.

"These damn things!" cursed Chase as it began moving. "What floor is it taking us to?" he whispered. Foreman shrugged, squinting thoughtfully through the darkness.

"It looks like we're on… the seventh floor," began Foreman when the staircases came to a halt.

"That's the floor!" exclaimed Chase. "Griffin doors are up here or something. According to the knight, of course." Foreman rolled his eyes.

"You know, he could've been lying…."

"Because everybody lies," grinned Chase.

"Who are you, House?"

Chase ignored him. "Well, let's see you come up with something better. The dormitories are supposedly behind the portrait of a 'fat lady.' Have you seen one?"

"I haven't seen anything. There's not a light on in this entire—ah!" screamed Foreman, running head-on into a large figure.

"Who are you?" gasped the teenage boy, backing up slowly. "Are you a Death Eater? Because I'll fight you! You'll have to kill me before I let you walk into the Gryffindor tower!"

"Mister Creevey," came a silky voice from behind Chase and Foreman, "I would gladly arrange that. Unfortunately, I've been given a rather tedious task of Muggle-sitting, and I fear that I shall have to Obliviate you." Colin Creevey squinted through the darkness, mouth opening and closing in fear.

"Snape!" he squeaked. "You—you don't scare me! I'll fight you! Expelliarmus!" he all but shouted. Snape waved his wand lazily and the disarming spell shot back at Colin, who was thrown against a wall.

"Mr. Creevey—if you would be so kind, what is the password to the Gryffindor tower?" The boy shook his head defiantly, now able to make out the faces of the two men next to Snape.

"I'll never tell! Who are they? New recruits?" he asked venomously. Snape raised an eyebrow.

"Since I'm obliviating you… they're Muggles. Doctors. I've no inkling as to what they're doing mulling around the castle at night. What, might I ask, are you doing, Creevey? Potter's not here! Why do you need the camera?"

"I was going to take pictures of the first night back at school—and how it's different, now that the war's going on," said the boy, looking at Chase and Foreman suspiciously. "What are Muggle doctors doing here?" As Snape answered the student and interrogated him about Gryffindor's password, Chase and Foreman exchanged a glance. They needed to do this on their own—without any magical people tailing them or hiding evidence.

After a few minutes, Snape raised his wand at Colin and said, "Obliviate!" A beam of red light shot out of his wand and made contact with Colin, who suddenly was sporting a very dazed expression. "Imperio. Mr. Creevey, please escort us back to your common room." Chase and Foreman watched, perplexed, as Colin stood up and began walking. They had both heard about the curse earlier today from Hermione, but seeing it work was a very weird experience.

Quickly, Colin reached the portrait of a fat woman in a pink dress. "Harry's revenge," he muttered, and the portrait swung open.

"Go back to bed, Mr. Creevey." And as Colin trotted across the red and gold common room, reaching the stairs, a voice sounded from the armchairs near the fire, and Snape collapsed.

"I've wanted to do that for years," smiled a slightly-overweight boy sitting in a red armchair. "Name's Neville. Who are you people?" Foreman and Chase exchanged a weary glance.

"Would it be possible for you to—er—let us be for awhile? We're not—what are they called? Death Eaters—not them. We just need to collect a few samples and we'll be on our way." Neville squinted at Foreman and Chase suspiciously.

"Why were you with Snape? I don't trust him."

"And neither do we," said Foreman testily. "Listen, kid, we're just doing our jobs…."

"Where are your wands? Give them to me, and I'll leave you alone."

Chase sighed and Foreman rolled his eyes. "Listen, we don't have wands with us."

"Whatever." He then looked over the two for a moment. "You're holding an Order coin," said Neville, nodding at Foreman. Foreman glanced down at his hands and realized that he was indeed still clutching the golden coin given to him by McGonagall.

"What's it to you?" demanded Chase defensively.

"Hold on," said Neville cautiously. "Relax. We're on the same side…I can tell you're not from around here, so I can only assume that the Order brought you in—there's no other way you'd have that coin. So I'll leave you alone. I'm going to bed—put that in your pocket, you don't want the wrong people seeing it," he advised as he stood up. Before retreating to the staircase, he kicked Snape viciously.

"There—he should be out cold for at least another thirty minutes. Cheerio."

"This is insane. Absolutely insane," hissed Foreman as Neville Longbottom walked upstairs. "Have you seen this magic do anything good at all? Every time it's been used people have been knocked out or their brains have been screwed with!"

"Well, it did help us with our luggage," responded Chase fairly. "But I know what you mean. I would almost rather be doing Clinic duty," he said sourly.

"Hey—maybe we'll wake up and this will all be a big dream," said Foreman, sighing. "All right. Let's start taking samples."

Miles away, the savior of the wizarding world opened his eyes.

"Harry!" gasped Ginny, who had been watching him as she daydreamed. "Oh, Merlin… Harry, can you hear me?" Harry Potter looked up at his girlfriend in a panic.

"G-Ginny… I need to—He's going to…." He shuddered as Ginny grabbed his hand.

"It's all right, Harry, you're safe…shh… calm down, love. Professor! You need to get in here!" she called out of the room. She heard footsteps running up the stairs and breathed quickly as she tried to calm Harry, who was perspiring and attempting to get up.

"What's the matter—" began Lupin, rushing into the room. "Ah. Harry, can you hear me?" he asked, kneeling at Harry's bedside.

"Voldemort," whispered Harry despairingly. "He—knows…knows I'm sick. Wormtail—how… where…?"

"You're in Grimmauld Place, Harry," said Ginny, stroking his hair worriedly. "You've been out for a month. Do you—do you feel all right?"

"No," said Harry, closing his eyes. "Something's wrong with me. A month? But what about—"

"Harry, everything is under control. Don't worry about anything right now. Lie down, Harry."

"Can't—I need to warn—"

"Harry, who do you need to warn?"

"Dumbledore!" gasped Harry, wrenching himself from Lupin's grip. "Malfoy is going to kill—" Ginny looked at Lupin, frightened.

"What is he doing?" she demanded.

"Dumbledore—stop! We can't—we can't go…"

"What do we do?" demanded Ginny. "Should we call the school? Get that doctor?"

"Draco!" shouted Lupin as he restrained Harry.

"What's all the bloody fuss about?" Malfoy asked, yawning, as he entered the room.

"Go Floo your Aunt Andromeda—tell her we need her and Ted, now!" Lupin then turned to Ginny. "Get to the school, Ginny, and tell Minerva that we need House and his doctors immediately. Tell her that once Andy and Ted make it over, I'll go and find Bill and Fleur—they have the key to the Gringotts vault Harry's paper is in, the paper that will tell House how to get here… go!" he all but shouted, beginning to sweat with the closeness to the full moon mixed with fear for Harry.

A bored-looking Draco and a white-faced Ginny nodded and ran downstairs into the kitchen. Remus held his breath as Harry suddenly stopped struggling and threw himself backwards, clutching his scar.

"Oh God, Harry…please stay with me…Harry, it's all right. You're safe here. Clear your mind," he whispered, terrified. He then looked up desperately. "James…Lil…Sirius…I'm trying, I am…where are you? We need him, we love him." A moment later, he heard two people thundering up the stairs. Remus jumped up.

"Healers Tonks!" he exclaimed. "Please—he woke up, and I think he's having delusions…now he says his scar hurts—that's only ever happened when Voldemort was connected with him!" Andromeda Tonks listened to Remus as she pulled on a lab jacket and felt for Harry's pulse.

"Remus, hand me the magenta potion in my bag, please," said Ted Tonks as he examined Harry. Remus nodded and pulled it out, handing it to Tonks, who poured it into a syringe and injected it into Harry's arm. Harry quivered for a moment and then fell still.

"That was a pain-reliever," explained Tonks to Lupin, who nodded.

"His blood pressure's gone down," said Andromeda worriedly, waving her wand over Harry's heart and muttering an incantation under her breath. "Whatever this disease is—it's mutated. I think it's possible that Harry's had it for years, but his magic has kept it down. Whatever he did before he fell into the first coma must have depleted his magical immune system."

"But his MIS looks completely normal," argued her husband, brow furrowed. "His heart rate is still to high," he frowned. "He seems relatively stable at the moment, though, besides that."

"Yes, his blood pressure is almost normal," Andromeda agreed. She heaved a sigh and looked at Lupin—her new son-in-law—and her husband wearily. "I hope we can save him."

"Don't we all?" chuckled Remus dryly.

"Mmm," Ted acquiesced. "Remus, have you got your wolfsbane for tomorrow?" Remus nodded, looking paler than ever.

"I do—but now that Harry's all right, I've got to run. I need to get the Secret Keeper statement from Bill. Will the two of you stay with Harry for the time being?"

"Of course we will," smiled Andromeda. "You take care, Remus. I think I'll have a little chat with my nephew while we're here…." Remus smiled.

"Good luck with that. Oh, and Nymphadora might be coming over tonight with the doctors. She's at Hogwarts right now."

"Wonderful," smiled Ted. "She never has time for us anymore, so it'll be nice to catch up, even though the circumstances are pretty bleak." Remus, who took this as a passive-aggressive lashing from his new father-in-law, merely nodded, ruffled Harry's hair, and hurried downstairs.

At Hogwarts, Chase and Foreman were finished with the Gryffindor tower and were making their way through the corridors, looking for any place that seemed a reasonable place for Harry to have spent time. As they walked blindly through a corridor on the second floor, Chase suddenly stopped.

"What is it?" asked Foreman, annoyed, as he ran into Chase.

"Someone's coming again," groaned Chase as two figures approached.

"Man, I would hate to go to this school," said Foreman under his breath. "How do kids sneak out at night?"

"Shh… come on, let's go back here!"

The approaching people were becoming clearer by the second, and their voices seemed panicked but familiar.

"So Remus is getting the key from Bill? Are you sure?"

"Yes! Positive."

"Are you sure Mr. Potter is all right?"

"Yes—no—I don't know! He was having delusions when I left. It was terrifying." Chase and Foreman stopped short and exchanged a glance.

"Do you see—stop! Why on earth are you out of bed?" exclaimed McGonagall as she and Ginny Weasley approached.

"Er—we're not students," said Chase hesitantly.

"Doctor Chase? Doctor Foreman?" asked McGonagall unbelievingly.

"Yeah—what's up? Do we need to leave?" asked Foreman.

"Don't you know the safety hazards in being out alone? This is a school full of magic! You're defenseless!"

"I wouldn't say defenseless," said Foreman, frowning. "I've had my fair share of conflict in my life and I know—"

"Be as that may," said McGonagall, cutting him off abruptly, "you all need to be careful. Are the other doctors still in the Heads' rooms?"

"As far as we know," answered Chase.

"Good. There's been a change—Harry's resurfaced from his coma. Ginny, would you like to tell them the story as we walk back to the Heads' dormitory?" The red-head nodded glumly and the group took off.

"I was sitting by him, and suddenly his eyes opened and he began to talk. He seemed perfectly normal for a moment, but then all of the sudden he changed. He began talking about a dream, saying Voldemort was after him…" Ginny paused, noting the oddity in two Muggles not flinching at Voldemort's name. "Then he changed again, flailing and saying he needed to warn Dumbledore. You know, our old Headmaster."

"The one who was killed?" asked Foreman thoughtfully.

"Yeah," said Ginny, shooting a glance at McGonagall. Then she looked back at the Muggle doctors. "What are you all holding?" Chase and Foreman looked at each other guiltily.

"Just a few samples," said Chase hastily. "We need to make sure that this isn't an— environmental problem or something."

"I see," said McGonagall. She was then quiet for a moment. "Listen. I really need your word that you all will listen to what we tell you; obey our rules. They all are for your safety and the safety of those around you. If you do what we tell you, you will not be in any life-threatening situations." Chase raised his eyebrows.

"That a guarantee?"

"I cannot guarantee anything. But that, Sir, is the closest I am going to get." Chase nodded slowly.

"Well I can't promise anything. Doctor Cameron, she's bad news. Doesn't listen to authority."

"Not at all," agreed Foreman, a slight grin playing at his lips. "She's the biggest problem at the Hospital. Everyone thinks she should go—but House won't fire her. We think there's something going on between them," he said in a very sincere voice.

"But no guarantees," grinned Chase.

"All right, then. Here we are." She said the password and the portrait swung open, allowing the four into the Head Common Room. "Now, will one of you go wake Doctor House? And Ginny, please go fetch Miss Granger, Mrs. Lupin, and Doctor Cameron." Ginny nodded, and Foreman began walking towards the staircase. "And Miss Weasley, just to warn you, your parents and several brothers may stay at Grimmauld Place tonight. I haven't spoken with any of them, but I am sure they are very concerned over Harry." Ginny nodded.

"Mum's going to try and persuade me to come home. I suppose I should, what with Harry sick and all—and school isn't the same, anyway." McGonagall nodded understandingly.

"Sometimes I wonder what's keeping me here," she said quietly, looking around the Common Room. Ginny smiled and headed up the girls' staircase, suddenly overcome with the desire to cry. She wiped her eyes as she reached the door and opened it.

"Tonks!" she whispered, pushing her slightly. "'Mione! Doctor Cameron!"

"Go away," groaned Tonks.

"No. Something happened to Harry—you all need to get up! We're moving the doctors."

"What?" asked Cameron sleepily, sitting up and rubbing her eyes.

"Come on. We're leaving Hogwarts. Harry changed. Everyone, get up."

"Oh my goodness, Ginny," gasped Hermione suddenly, shooting up. "Is he okay? What's wrong?"

"He's fine," said Ginny tiredly. "He just woke up and all these changes are happening—just come on. Come downstairs as soon as you can. And don't worry about your luggage, Doctor; just wear something. The House Elves will bring the rest over." Hermione frowned, but restrained from saying something about cruelty towards House Elves, just as Cameron restrained from asking what on earth 'house elves' were.

"I'll meet you downstairs," said Ginny, yawning.

"No, I'm ready," said Hermione, pulling on a T-Shirt and jeans.

"Me too," said Tonks. "Is Remus with Harry?"

"No," said Ginny as Cameron dug through her suitcase for a shirt and some pants, "He went to get Bill so he could find the parchment of Harry's."

"It's a good thing we kept that," said Tonks quietly.

"No kidding," agreed Ginny.

"All right…I'm ready," said Cameron, pulling her hair back into a ponytail. Ginny led the way downstairs, where House, Foreman, Chase, and McGonagall were already sitting waiting.

"Remus and Bill haven't arrived yet," said McGonagall. "It may take awhile yet. So please make yourselves comfortable. Would anyone like anything to drink?"

"I'll take a coffee," said House seemingly totally alert already.

"Make it two," said Tonks, blinking and rubbing her eyes. "I've a feeling I won't be getting much sleep tonight."

"Three, please," added Cameron.

"Anyone else?" asked McGonagall. When nobody answered, she called out.

"Dobby!" A loud crack sounded and the doctors stared, perplexed, as a House Elf appeared out of thin air.

"Yes Professor? What is Dobby being able to do for you tonight?" He then spotted Ginny and Hermione. "Miz Wheezy! Harry Potter's good friends! Can Dobby be of service to you?"

"Three coffees, please," smiled McGonagall. And a tea for myself."

"Of course, Ms. Is Harry Potter getting better, Ms. Professor?"

"We're not sure yet, Dobby," said Hermione kindly. "But I'm sure he'd love to know that you asked about him." Dobby nodded eagerly and disappeared.

"What the hell was that thing?" demanded House not a second later.

"A house elf," said Hermione in a disapproving tone. "Wizards and Witches practice a type of slavery over them." Ginny rolled her eyes. "It's horrid."

"And that greasy man implied we were the barbaric ones," commented House offhandedly.

"There are certain practices in which the Wizarding world is far behind Muggles," explained Hermione with earnest, "especially social issues. Why, Purebloods in this world are all inter-related."

"Eew," said Chase. "You mean they marry people in their family?"

"No," said House, rolling his eyes, "Inter-related means they have no familial ties whatsoever." Chase sighed, annoyed, right as Dobby reappeared with a platter of steaming mugs.

"Here you is, Professor; Mrs. Lupin—Miss; Sir."

"God, actually," corrected House.

"Here we go again," muttered Cameron, sipping her coffee carefully. The house elf looked between the two with some confusion but then seemed to think better of it.

"Tell Harry Potter that I is knitting him socks to help him get better," said Dobby with excitement.

"Thanks, Dobby, I know he'll appreciate that," said Hermione, smiling. Dobby beamed and then was gone with a loud crack. The room fell silent for a moment before House began interrogating the witches sitting with him.

"So—what exactly are all of your relationships with Harry? How long have you known him, that sort of thing."

"Well," began Hermione quickly, "I've been best friends with him since our First year—I believe it's the equivalent of sixth grade in the United States?" House nodded slowly.

"And my brother is Harry's other best friend," said Ginny. "He's spent quite a few summers at our house. I'm a year younger than those three, and I recently dated Harry for a few months."

"But you broke up?" pressed Chase curiously.

"It was stupid," said Ginny, lowering her eyes slightly. "He didn't want me to be in any danger—"

"Sure he didn't," said House sarcastically. Ginny looked up at him angrily.

"You don't know what you're talking about. You don't know him!" she hissed, a fire blazing in her eyes.

"And what about you?" asked House, ignoring her. Cameron looked at Ginny sympathetically.

"I have been his Professor for six years," said McGonagall. "I also taught his parents and was his Head of House."

"And I'm his old godfather's second cousin," said Tonks, still not quite awake, "I have only known him for about two years."

"Old godfather?" asked Cameron.

"He died. A little over a year ago—one of the many emotional traumas the poor boy has suffered," said McGonagall sadly.

"Name some more of these experiences," said House, frowning. "What about before he came to school? Did he live in an orphanage?"

"No," said Hermione. "He lived with his Aunt and Uncle and cousin—"

"The person I talked to said he didn't have family," said House, frustrated.

"Well—I mean, they're Muggles, and they haven't acted like a family by any stretch of the imagination," began Ginny, but she was cut off by Foreman.

"So because they aren't magic, you don't count them as family?" he demanded. Ginny sighed and was about to explain, but a sharp knock sounded at the door.

"Who is it?" asked McGonagall, standing up worriedly.

"Remus and Bill."

"Wait," said Tonks quickly, "The question. Remus, what was your first pet's name?"

"Tonks, do we really have to—"

"Yes! Answer the question."

"Rascal," said Remus, clearly annoyed.

"Bill," began Ginny, "Which sibling's leg did you break?"

"George—and it was an accident!"

"Let them in," said Ginny. The portrait swung open and Remus Lupin walked through it, Bill Weasley close behind. Ginny ran up to embrace her older brother, and Tonks squeezed her husband's hand.

"All right. Here's the parchment," said Bill, digging through his pocket and pulling it out. He handed it to Cameron, who was closest. "I'm Bill Weasley—I don't think we've met. I'm Ginny and Ron's brother."

"How many are there of you?" asked Foreman, noting that Bill had apparently broken the leg of another sibling once.

"Seven," answered Ginny, grinning. "I'm the only girl, and the youngest. Bill, this is Doctor Cameron." She smiled.

"Allison," she said, taking in Bill's appearance curiously. He had deep scars all over his face—but she could tell he was still a handsome man, and he wore a fanged earring. His long red hair was pulled back into a ponytail.

"Nice to meet you," smiled Bill, nodding. "And you are—?"

"Robert Chase. This is Eric Foreman—and—"

"I'm Doctor House," said House, limping towards Bill and shaking his hand.

"All right, everyone," said Lupin. "You all need to memorize this address. We're going to go through a fireplace. When you say the name of the place we're going to—Number 12, Grimmauld Place—think of the address or else you'll get lost. And we don't want that happening. Any questions?"

"Did you say a fireplace?" asked Chase politely. Hermione laughed.

"It's kind of nerve-wracking the first time," she admitted. "But it's not bad. You might get a bit dizzy…just don't get lost, and say the address very clearly. Understand?" Everyone nodded despite several blank looks.

McGonagall reached for some Floo powder and threw it into the fireplace, in which a small flame was dwindling. It suddenly shot up and turned a bright, sparkly, lime green.

"We have to go into that fire?" asked Cameron nervously as she passed the address to Foreman.

"Here, some of us will go before and after you all. Professor, are you quite sure that the fireplaces are not being monitored?"

"I removed the surveillance on this room personally," said McGonagall in a business-like manner. "We will be fine for the time being." Hermione nodded, convinced.

"Walking into a fire," repeated Chase skeptically. "House help us."

A/N: Hey, sorry it took so long! Thank you to everyone who is reading this story. It's kind of weird still, but I hope you like it. PLEASE review.
