"They want us to go undercover where?" Rossi asked incredulously.

"Princeton Plainsboro Teaching Hospital," Hotch repeated, "As fellowship candidates for Dr. Gregory House."

Rossi nodded, "Remind me again how exactly this came about."

"The hospital has been receiving letters threatening Dr. House's life. The police have compiled a long list of possible suspects with some kind of grievance against him. And until that list can be narrowed down, they want to have someone monitoring him at all times in case he should be attacked."

"Then why do we have to be undercover?" Morgan asked, "Can't someone just guard him?"

"Let's just say he'd be unlikely to cooperate... He has kind of a reputation..."

"So, how are we supposed to pose as believable doctors when we have no medical training of any kind?" Emily asked the most pressing question.

"We're all going to take a short course to cover the medical basics, obviously it will require some research," Hotch explained. "At no time will we be alone with a patient nor will be performing any serious procedure without the help of a senior doctor."

"Hang on," Reid said, something from the beginning of the conversation niggling at the back of his mind, "Did you say fellowship candidates?"

Hotch nodded. "He's just lost his team of three fellows and is holding kind of a group interview to look for fellows to replace them."

"How exactly is he going to be deciding which candidates get the job? Won't it be obvious that among a small group of job candidates, six of them have no real medical knowledge?"

"No, not really..."

The team walked into the lecture theatre where they had been told to meet Dr. House and the other fellowship candidates. The white coats they wore and the stethoscopes around their necks felt strangely out of place. They stopped in their tracks when they saw the crowded hall. Suddenly, the numbers they had been given made a lot of sense...

A/N: A new kind of House/CM crossover, since the first one was so much fun. As you can see, this takes place at the beginning of the fourth season of House. Updates might be kind of sporadic, since I'm still unsure how this one will work out. See my poll to give your input.
