Harry woke from a fitful sleep to the sound of the door to his room sliding open. He cracked his eyes open to look at his new arrival. "Harry, dear," came a sympathetic voice from the doorway.

"Mrs. Weasley!" Harry said in surprise, sitting up quickly. Seeing that he was awake, the plump woman rushed to Harry's bedside and leaned down to give him an awkward hug.

"Thank goodness you're okay," she said. "I was worried sick about you."

"I'm feeling loads better," Harry grinned. "Really."

"That's just grand, dear," Mrs. Weasley replied with an anxious smile. "Arthur really wanted to be here, but they're keeping him way overtime at the Ministry, what with all this concern over You-Know-Who."

"Don't worry about it," Harry assured her. "I'm glad you could come."

Mrs. Weasley opened her mouth to reply, but they were interrupted by a noise at the door. "Hey Harry," Chase said, entering the room. "How's your stomach doing?"

"It only hurts a little," he said.

"On a scale of one to ten, how would you rate the pain?"

Harry thought a moment. "Maybe a three?" he said tentatively. Chase scribbled something on Harry's charts. "Is that good?"

"It's…good," Chase said. "We can't be sure that it won't come back. But this should help us figure out what is—or was—wrong with you."

"Oh, that's fantastic!" Mrs. Weasley exclaimed, relieved.

"Yeah," Harry sighed. "Oh, er, Mrs. Weasley, this is Dr. Chase."

Chase looked up. "What?"

"This is Mrs. Weasley," he said, motioning towards her. "Ron's mom."

Chase looked in the direction that Harry was pointing. "Harry…" he began slowly. "There's…no one there."

"What?" Harry asked, confused.

"There's no one in the room besides us." Chase looked extremely concerned.

Harry's breath began to quicken. "What do you mean?" He looked over at Mrs. Weasley, who looked worried. "What do you mean?" he repeated. "I see her. She's right there."

"I'll be right back," Chase assured him, rushing out of the room. He ran down the hall and yanked open the door to the diagnostics room. "Foreman!" he called. Foreman looked up from the paperwork he'd been finishing for House. "Foreman. Call Cameron. He's hallucinating."

"Nothing causes these symptoms," Chase groaned with his head in his hands.

"Something does," House snapped. "Otherwise he wouldn't be having them."

"Dehydration?" Cameron shrugged. "Could be causing the vomiting, or due to it."

"He didn't throw up enough to become dehydrated enough to have hallucinations. What else?"

"Stress," Chase said simply.

"In the less optimistic department, a brain tumor," Foreman suggested.

"Check for both," House informed them. "Ask him about stress, MRI his head." Foreman, Chase, and Cameron stood. "And Cameron," House added. "Try not to go on anymore dates with teenagers while they're here." Cameron blushed and hurried out of the room. Chase followed.

"What was that about?" he asked, in a would-be-casual voice.

"I don't know what he's talking about," Cameron said unconvincingly. They reached Harry's room and Cameron went inside before Chase could continue the conversation. Foreman continued down the hallway to set up the MRI, rolling his eyes.

"Hi," Cameron said. "How are you feeling?"

Harry just shrugged. He looked pale and worried. Hermione and Ron looked about the same. They were both sitting at the foot of Harry's bed, watching him anxiously.

"We're going to have to ask you some questions," Chase said when no one replied. "Just to see if we can get a little history that might help us diagnose you."

"Whatever you need to know," Harry replied.

"We should probably talk to all of you," Cameron began, looking at Chase. Chase nodded.

"Ron, Hermione, you two can come with me," Chase said, beckoning to them to follow him out of the door. Cameron took a seat in the chair next to Harry's bed.

"So, about how much homework do you have a night?" she asked once Chase, Ron, and Hermione had left.

"About three, four hours," Harry shrugged. "It depends."

"That's a lot," Cameron noted.

"I got used to it. It's been that way since about second year."

"Has there been any dramatic increase recently?"

Harry thought a moment. "Nope," he said. Cameron jotted down some notes.

"How about extra-curricular activities?"

"I play Quidditch," Harry said.

"And how often is practice?"

"Twice a week, whenever the captain can manage it."

"Okay," Cameron scanned the list of questions she was supposed to ask Harry. "Do you feel stressed out a lot?"

"Not really," Harry said. "I mean, sometimes, yeah, but not usually. Hermione's the stressed one, not me."

"How've you been eating lately?"

"Normally," Harry sighed. "Listen, I think I would know if I had problems with stress or something."

"Alright," Cameron said. "I believe you. That's almost the end of the questions anyway."

"Okay," Harry sighed. "Will the hallucinations come back?"

Cameron looked at Harry sadly. "We can't know until we find out what's wrong with you. Which should hopefully be very, very soon," she promised.

There was a noise as the door slid open, and Foreman poked his head inside. "You ready?" he asked, directing his question at Cameron.

"We're done," Cameron nodded.

"Great," Foreman said. "Harry, we're going to do something called an MRI. It'll take a picture of your head, and let us know if anything is wrong."

Harry nodded, looking slightly nervous. "Should I get up?"

"That'd be great," Foreman smiled. "It's just down the hall." Harry began to climb out of the bed.

"I'll get Chase," Cameron said. She turned and left the room, making her way down the hall and towards the waiting room, where Chase was talking to Ron and Hermione. Meeting his eye, she shook her head slightly.

"Alright," she heard Chase say to Ron and Hermione. "You guys can go back to Harry's room." Cameron made her way over to Chase.

"I'll be there in a minute," Hermione told Ron. Ron shrugged and headed back to the room.

"It doesn't seem like stress is a factor," Cameron told Chase wearily.

"Yeah, that's kind of what I got too," Chase said.

"Foreman's taking him for the MRI."

"Good," Chase paused. "What did House mean about you going on a date?"

"God, Chase," Cameron groaned. "I went to grab a drink with Ron because House was messing around. It was nothing." Hermione, who had been unnecessarily unpacking her bookbag, looked up suspiciously.

"That's…funny," Chase said finally.

"Yes, it is," Cameron rolled her eyes. "I'm laughing."

"No, I mean…" Chase pretended to think carefully. "Oh, that's right. When I asked you if you'd like to get drinks, you said we should get Harry better first. But then you went to have drinks with the kid. I get it."

Cameron glared at Chase. "Sorry, you weren't there," she snapped. With that, she turned abruptly and marched back down the hall towards House's office. Chase watched her go with a pang of regret, but also with a great deal of annoyance. He turned around bitterly, only to see that Hermione was standing right behind him.

"Sounds like you have a bit of a problem."

"I'm fine," Chase said rather harshly.

"You don't need to give me that," Hermione said. She drew closer to him and lowered her voice. "I get it. I like Ron."

"You—what?"

"Him going to drinks with Cameron bugs me as much as it bugs you. So I sympathize."

"Well, thanks," Chase said, not looking thankful at all. He turned to go back to the diagnostics room.

"Wait," Hermione said. She placed a hand on his arm. "Maybe we can help each other."

Chase turned around with a sigh. "Look," he said. "It's not like that. Cameron and I are…kind of in a relationship."

"Oh, I can see that," Hermione said with a disbelieving chuckle. Chase narrowed his eyes.

"What's that supposed to mean?"

"I mean, it sounds like she's really into you, the way she agreed to get drinks with you and everything."

"Look," Chase gave Hermione a challenging glare. "You think what you want. I don't need to play childish games to get her to be my girlfriend."

"If you say so." Hermione smiled coyly. "Well, I'll see you later, Dr. Chase." She turned around and started to walk away. Chase stared after her, thinking about what she'd just said.

"Alright, what do you want me to do?" he called after her finally. Hermione turned around with a smile.

"You keep her away from him, I'll keep him away from her," she said. "Easy enough."

"Okay," Chase said. "I'll do it."
