A/N: All medical "facts" are in fact (hehe) wrong and totally made up. I mean I could by some miracle have some things right but I really doubt that, so yeah, don't diagnose yourself on what I say because really the existent of my medical knowledge his how to treat a headache…

"Okay, people," House said limping in to the differential room, "differential on why some one would want to date Chase." He threw April-May's file on the table, and walked to the white board.

"She is not my girlfriend," Chase protested coming in behind House; fixing the cuff on his backup work shirt that he kept in his locker.

After House heroically fled Chase to save April-May from cardiac arrest and Chase poured about four gallons of coffee down his throat House agreed to let him work that day. Plus he needed all the brain power he could get—April-May's simple blood clot turned into a puzzle when she fell into cardiac arrest. She just had the clot removed the problem should have vanished. This intrigued House, so when Chase asked him to take the case it really didn't take much begging at all.

"I think it's the hair," House concluded studying Chase. "What do you guys think?" House turned and looked at the non-blonde population of his team. Chase tilted his head to the side to glare at House. This made his hair fall in front of his eyes. "Oh yeah, it's the hair," House confirmed.

Cameron and Forman were studying the patent's file and ignoring House's juvenile banter. "Drugs, cocaine could cause the blood clot and seizure. And the antibiotics they gave her during surgery could cause the cardiac arrest if the coke she was using was contaminated," Forman said jumping into the differential.

"No, she's clean," Chase shot Forman down. He had a look in his eye that he didn't quite believe what he was saying. House saw it but didn't say anything.

"So, she used to take drugs… It could have weakened her immune system. And when she hit her head a bacteria could have gotten in and caused the clot and seizure. The antibiotics she was given were fighting off the bacteria during surgery and when she was taken off them she went into cardiac arrest," Cameron chimed in believing the best in people, like always. Although, she did realize that contaminated cocaine and lie was much more likely.

"Or if it is a bacterium it could be environmental," Forman added.

"How many types of bacteria could do that?" House asked throwing his ball in the air and then catching it with his cane.

"Dozens," Cameron answered.

"And presuming your theory is correct how many can live off a bar floor,"

"Maybe… two dozen,"

"Test for them; take the lover boy back to the bar and get samples. And while your at it do a tox screen incase Forman is right," House ordered. Cameron and Chase left to see to their taskes leaving Forman and House.

"What should I do?" Forman asked, always eager to please.

"Get your coat. We have to break into Chase's apartment," House said getting up.

"What?" Forman asked astounded.

"She has been crashing at his place the last couple of months. I couldn't get Chase to help me because that would be no fun and Cameron would chicken out. So that leaves me and you," House threw Forman the ball and started towards the door. Forman rolled his eyes and switched his lab coat for his leather jacket.

"We can take my car," Forman offered knowing the rude and brilliant doctor was right.
