Disclaimer: I do not own Criminal Minds or House MD. All original characters belong to me. Any similarities to real life persons, in name or description, are strictly coincidental.

Author's Note: These two shows contain teams of people that are amazing at what they do; profiling criminals and medical diagnosis respectively. I thought it would be interesting to combine these two shows, therefore, the birth of this story. There will be no formal pairings, except those already depicted in the show. There might be a little Hotch/Prentiss; we'll see how that goes as the story goes on. Also, I am not a doctor. Therefore, the medical information might not be correct. All I have at my disposal is the internet, and whatever I've learned from watching House and other medical shows. So don't get angry if something is wrong.

This story takes place during the current times of both shows. So that would be in the middle of Season 5 for Criminal Minds, and Season 6 for House.

Hope you guys like it.

"Tyler Beckman! FBI!" Morgan's hand fell on the wooden for the second time. Knocking had not been enough, and he had to raise his voice to make himself possibly heard to the man they were trying to reach. He glanced back at Emily and Hotch, a questioning look on his face. Emily had her hand resting on the Glock attached to her hip, and Hotch had his arms crossed over the Kevlar vest. "The guy's not coming to the door. His car's here, but he might not be home-"

But before the dark-skinned agent could even contemplate kicking down the door, he got his answer as to whether their suspected UNSUB was home. A stocky man with brown hair had run out from behind the house, in a futile attempt to escape unnoticed.

"Hey!" Morgan shouted, and began to run after Beckman, with Hotch and Emily right on his tail. The suspect's house was located in a quaint neighborhood in a small town in New Jersey; the kind of neighborhood, filled with children and families, that you would never suspect a serial killer to be living. Their heavy footfalls disturbed the quiet air of the area, as the three agents weaved in between fences and bushes through backyards.

And then Morgan had finally caught up to Beckman when a fence too tall to leap over blocked his way. Taking a hold of the man's shirt with one hand, Morgan slammed him into the chain-link fence, the other hand grabbing for his handcuffs.

"Why are you running man?" He said nothing; he was breathing too heavily to speak. Yanking him roughly to his feet, Morgan looked around, confused when he did not see Emily and Hotch there with them. Hadn't they been behind him only seconds ago? And then he spotted the two of them, and terror gripped his heart like a vice.

Emily was about twenty feet back, kneeling on the ground, clutching at her chest, coughing violently. Hotch was bent over her, his hand on her back, talking to her. Hotch glanced up at him.

"Get Beckman back to the station. I'm taking Prentiss to the hospital."

"House? Hou- Oh, there you are." The doctor sat in his office, leaning back in his chair, his legs propped up on his desk. He peered up from behind the magazine he had been flipping through with an amused expression on his face.

"What, this wasn't the first place you looked for me?" Cuddy put her hands on her hips, looking exasperated. The chief of medicine had a feeling that it was going to be a long day.

"Well, you're not usually in your office when you don't have a case. You're usually hiding from me."

"Why would I want to hide from you?" he taunted, pretending to pout.

"House." Now there was a hint of a warning tone to her voice. "Where's the rest of your team? Why aren't you working on a case?" He shrugged.

"I told them to find me an exciting case…down in the clinic."

"Getting your team to do your clinic hours is only going to earn you more. And-" She pointed to the stack of files perched haphazardly near the edge of his desk. "-you have plenty of cases right here for you to take. Get to work on one of those, or go down and do your clinic hours."

"But Mom!" He dragged out the vowel, sounding like a whining child.

"House, I mean it. Or else." And with that, she spun around on her heel and walked out the door. Too bad she really never followed through on her threats. Countless times she had threatened to fire him, but it had never happened.

Though, she did have a point. The team hadn't had a case for a few days now, and he hadn't yet spared a glance at the files on his desk. But going through each one was a tedious task. With a grunt, he pulled himself to his feet. He was going to head to the ER. Perhaps he would find something interesting there.
