AN: This is just something I started for fun! It's my first fanfiction, so I'm really nervous. English is not my first language, so don't judge me for any misspelling or grammatical mistakes. Hope you like it!

It was a normal day at PPTH's diagnostic department, Foreman thought, he had just came back of his clinical trial with Thirteen, who was now talking with Kutner over the coffee maker about the lack of patients today. Taub got the unfortunate task of doing House's clinic hours. He was just about to get up to get a cup of coffee too when he heard the loud "bang" noise of House coming in slamming the door behind him.

"18 year old patient, female, came in presenting various symptoms…." He said throwing the chart to Foreman and banging his cane over the table next to him.

Foreman picked it up quickly and started examining the file… I seemed like a normal case of flu, he didn't see anything that would get House interested and that made him very curious.

"What's the mystery here? She probably just exercised a lot or something and has a flu. I don't see any big mystery that would get you interested"

"Look at the name" House said abruptly.

Curious, he did what he was told and got surprised "Claire Katherine Chase" he said aloud. Sure, he thought, it was curious, but there are many Chase's in the world and not all of them are connected, but still, looking better at the file he saw that the patient was from Melbourne, Australia, exactly where….

"You're not thinking…" he started.

"Oh, yes, I am" House said in a very House-like manner "And don't say you're not thinking it too" he added piercing Foreman with his eyes.

"Well…" Foreman started, but was interrupted by a very puzzled Thirteen:

"What's going on? What are you guys talking about?" She asked looking at Foreman with a confused look and giving him a little smile.

Foreman felt quite uncomfortable, he wasn't quite sure about his situation with Thirteen, sure he was treating her in his clinical trial, but lately he felt that something else was going on and he couldn't quite figure it out. Foreman thoughts were interrupted by House who started explaining in a bad mood because Foreman was the only one who had got his amazing discovery:

"Well, me and Mr. Trial here are thinking that we've got a curious stranger family case going on here"

Thirteen looked puzzled "Curious stranger family case?"

"Exactly, now, if you and your not understanding excuse me I'm going to visit a patient" he said while limping out of the glass doors and leaving a stunned Thirteen behind.

"Did he just say he was going to visit a patient?" she asked still shocked.

"I think he did" an also shocked Kutner, who was listen everything carefully answered.

"Well… that's… new. And I still don't get it!" She said while picking up the patient chart "what is it about this patient?" she asked Foreman.

"Don't worry, you'll get it" He said smiling at her reassuringly "Now, I got to go find House before he does something very… House" He said before rushing to the door after his boss. Knowing that nothing good could come out of his little visit.

OoOoOoOoOoOoOoOoOoOoO

House was limping cross the hallways until he arrived at room 248. He was really excited about this; he had had nothing to do lately to escape the boringness except messing with Wilson and Cuddy. This would be a nice little treat for the week. When he was just about to enter the room, Foreman caught up with him.

"Hey, you, out!!" House shouted at him.

Foreman didn't back away, but stood beside House and put his hands on the doorknob.

"No way, I don't want anybody being traumatized by you today"

"Me? Traumatizing someone? Well, that was just mean of you." House said with a false feelings hurt voice.

Foreman looked at him with a skeptical face.

"Fine. But I'm not going to traumatize her. I'm just going to ask her some questions and YOU are not going to be around to witness it" he said, pushing Foreman away from the door and walking into the room.

"Well" Foreman thought "Then there's someone else I need to warn about it" and with that he went running down the halls in the direction to the ER.

OoOoOoOoOoOoOoOoOoO

Happy for have gotten rid of Foreman, House walked into the room.

"Hello, I'm doctor House, your attending physician"

"Hum... hello, pleased to meet you" Claire said in a thick Australian voice, and also a very soft one. And then House looked up at her and felt his jaw drop. She was beautiful, long, kind of curly, blond locks, sea-blue eyes… and the most surprising is that the more he examined her the more the traces of her face and jaw line brought up similarities with… well, that just gives him more confirmation in his suspicious.

"So, you came here with strong muscle pain, dizziness, running nose…" he listed as walking closer to her and putting his cane on the table on the end of the bed "I'm gonna have to ask you a few questions"

"Sure, anything" She said, sitting up more straight.

"Do you have any history of diseases?" . He thought that starting with some more normal questions would be the best.

"No, but I got my tonsils removed!" she answered, after thinking a little.

"Great nothing!" House thought. "Uhm… Good to know, any history of cancer and other genetic diseases in your family?" he asked.

She lowered her head and started examining her hands.

"Ohh... yes, my grandmother and my father had cancer. Skin and lung respectively" She said now a bit saddened "And my mom just died, she had Parkinson's"

Ohh, now this was getting waaay warmer, he thought, a father with lung cancer… that ringed a lot of bells.

"What's the reason of your visit to the States?" he said, walking a little closer to her.

"Uhmm… well…" she looked a little taken aback by this question, and started curling her hair in her hands "I'm here to… because… well… I'm looking for someone"

Now, House's heart started beating faster, this was definitely going somewhere and somewhere good.

"You see" she continued "After my mum died I got left alone, but before that she told me that I still had someone, that was kind of family… Half-family and that he lived here, in New Jersey, so after her death, I went looking for him… but I don't wanna talk about it" she said lowering her head again and looking at her feet, clearly not comfortable by talking about that with someone she barely knows.

"Shit" House thought, his suspicions were pretty much all confirmed, but she didn't wanna talk about it and he couldn't just push her into saying anything, because that would raise suspicions on her part. So he decided to wrap it up.

"Okay then, my team will be back to examine you in a while" he said walking to the door.

"Thank you doctor" he heard she said before he shut the door and got face to face with Wilson.

"So… I was passing by your office when Thirteen and Kutner aborted me, because of a not interesting patient that House went to visit…" he started, moving his body back and forth and looking intensively at House "A good way of starting the day I'd say" he said sarcastically in a very Wilson like way.

"It is a great way, actually" House said as he started walking down the hallway with Wilson following him "And Thirteen and Kutner didn't see anything interesting on the patient because they are to dumb and to worried with my mental health for wanting to visit a patient" He concluded and stopped walking.

"Well, you can't blame them; a lot of people are worried with your mental health" mocked Wilson and stopped beside him "Where did you get this case anyway?"

"I may have hijacked the file when I saw the name out of the nurse's station… but you're skipping the point!!"

"When you saw the name??" Wilson asked puzzled "Well then, go on… at least you have a point…" he said making a 'continue' movement with his hands to House.

"Since when I don't have a point?" House asked raising his eyebrows "Yess, the name, because, my dear Mr. Skeptical, I have great reasons to believe that the patient, my friend, is Rowan's Chase daughter, and our Chase's little mysterious and unknown half-sister!!"

Wilson looked taken aback, clearly considering this information and concluding that it was crazy.

"How many Vicodins have you taken today?" Wilson asked shocked

Ignoring him, House just rolled his eyes and limped away, with the certainty in his head.
