"No head trauma, negative for Kleine-Levin, negative for Paget's and Von Economo," House said. "Are we sure this guy's really asleep? Maybe he just doesn't want to go to Cleveland."

"Who would?" Wilson said. He was sitting at the head of the table, eating a salad. Cameron wasn't surprised; she'd noticed that whenever House's leg was especially painful, Wilson would appear at differential diagnoses.

"That many babes show up in your hospital room and you don't wake up, you're really asleep," Chase said.

"Well, you would," House said. "But we don't know much about this guy...which is strange, isn't it? It's not just that we don't have a real medical history. All these girls around, we should know his childhood pets' names and who popped his cherry."

"Faith," Chase said.

Everyone turned and stared at him.

"Faith popped his cherry?" House said. "He lost his virginity to religion?"

Chase laughed. "Faith's the fourth girl. She was there when we did the MRI."

"But she didn't say anything about...about that," Cameron said. She knew she'd been busy with the MRI, but she would have noticed that.

"She said her relationship with him was complicated," Chase said. "I just got that vibe."

"There's a vibe that tells you who popped people's cherries?" House said. "You really are multi-talented."

"Thanks, I think," Chase said.

"It doesn't matter," Foreman said. "Unless that happened recently, which I doubt. We need to focus on what could cause excessive sleep in a healthy young male, not act like we're sorority sisters."

"Hey," Cameron said.

"It could be Minimata disease," Foreman said. "We should check his blood for mercury."

"He was in Africa, not Japan," Chase said.

"Yeah, because pollution only occurs in first-world countries," Foreman said.

"He'd be sicker if it were Minimata," Chase said. "He's asleep, not sick. Plus, it's usually congenital and chronic, and this is acute."

"It really is strange," House said. He had his leg propped up on a chair and was absent-mindedly massaging his thigh. "His only symptom is that he won't wake up."

"We don't know that," Foreman said. "He can't tell us about any other symptoms, because he's asleep."

"It's like a fairy tale," Chase said.

"I take it back about the multi-talented," House said. "Unless you want to kiss him to wake him up; I could collect admission from half of the nursing staff to see that."

Cameron was trying to ignore them. She held the MRI results to the light. "There's nothing in the reticular formation that would cause excessive sleep, and there should be," she said, feeling extremely frustrated. "No lesions, no swelling, no scarring, even...nothing."

"If it's not in his brain, it must be something systemic," Wilson said, and Cameron could have kissed him, she was so grateful he was paying attention to the medicine.

"Lyme disease can cause sleep disturbances," she said.

"No bulls-eye rash," House said.

"It doesn't always present with the rash," Cameron said.

"True, but hello, Africa," House said. "The one thing he really can't have is Lyme disease."

"He wasn't in Africa his whole life," Cameron said. "He could have had it before, not treated it completely, and it's reemerged."

"It's not in his file," Chase said, paging through it.

"Just because Dawn didn't know he had it, doesn't mean he didn't," Cameron said.

"No, but Lyme disease wasn't very common in California when he was living there," House said. Then he completely shocked Cameron by actually picking up the file. "Does anyone else think this is a rather thin file? It's almost as though he barely existed until a few years ago. And what was he doing in Africa, anyway? All those hot babes waiting for him here, and he's over there?"

"I think that had something to do with Faith, too," Chase said.

"Thank you, Dr. Phil," House said.

"Dawn said he was with Doctors without Borders," Cameron said.

"He's a doctor?" Wilson said. "He's a bit young."

"Says the boy-wonder oncologist," House said, and Wilson made a face at him.

"No, he's in construction, I think," Cameron said, paging through her notes. "I think he built things for them."

"MS," Foreman said suddenly.

Cameron shook the MRI a little. "No plaques," she said. Foreman always suggested MS.

"Well, then, what do you think it is?" Foreman said.

Cameron sighed. "I have no idea."

House looked around at all of them. "This guy is going to be the next Rip van Winkle if we can't figure this out." No one said anything. "All right, there's nothing else you can do now. Go home, get some sleep...just not too much." He got up and limped into his office.

When Cameron left, she saw that he was still there, poring over his medical books.
