Little Cuddy makes an appearance in House's office and shocks everybody in the room. Rachel is almost six.

"House! House! House!"

The chanting could be heard from the front entrance of the school and Cuddy can't hold the smile. House was supposed to pick her up but due to his patient having five seizures in the past three hours, he'd had to stay in the hospital.

Rachel appears through the doorway and stops in her tracks before continue as she was before, only changing her chants.

"Mommy! Mommy! Mommy!" she throws her Ladybug backpack on the floor before hugging her mother. "Mommy, where's House?"

"His patient got worst and he had to stay to take care of him." Rachel pouts, but that broke with all their plans!

"But House promised we go to the costume shop! It's almost Halloween! And then he had to help me do that report 'bout what Mommy and Daddy work for! You already did it, it's his turn!" Cuddy picks the backpack from the floor and takes her daughters hand. They walk to the car and she buckles Rachel in her seat.

"Well, you can't go shop for the costume, but I have to go back to the hospital so you can do the report." Rachel thinks it over and nods, satisfied.

"– and you are all useless!" with the end of the rant, House turns around and paces through the room. His team deflates and they look at each other. He stops and looks at them. "What the hell are you still doing here?! Go run the tests!" they scramble out of the chairs and exit the open door in such a haste that they completely ignore the little child waiting patiently at the side.

Rachel had escaped her mother's grasp as soon as the hospital doors had closed behind then and had raced to the elevator. She had asked one of the nice nurses to push the button for her and had race through the halls to House's office, only to find him chastising his team. Knowing he'd ignore her until he was done, she waited for the team to exit the office to enter herself.

"House!" he turns to her and his irritated face melts into a little smile he reserves to her and her mother alone. He takes his hands from the table he'd been reclining on and accepts her hug.

"Hey, Mini-Cuddy. We won't be able to go buy the costumes." Rachel just shakes her head and jumps on a chair.

"We'll go another day. Mommy said your patient is very sick so you have to stay. But we could do the report!" she pats the chair next to her and takes her folder out of her bag, she picks one of the paper sheets that have the questions printed and takes a pencil from the table. "Let's see… Name: House."

"No, Rachel. Greg House. House is my last name." she looks confused and then nods.

"How old are you?" she looks at him and he raises a brow.

"It's confidential."

"What does that mean?"

"That it's secret."

"Oh… I don't know how to write that." So House writes it for her. "What's your job?"

"I'm a Diagnostician in the PPTH." She writes it down and House corrects her when she puts a C instead of a G.

"And what's that?"

"I get patients and tell them what's wrong with them." Rachel pauses in her scribbling to look at him.

"But that's what all the doctor do." She pouts, not understanding.

"Yes, but the difference is that my patients have gone to who-knows how many doctors and they still don't know what they have. So they bring them to me because I'm the best." The little girl bounces on her seat as she writes it down, clearly exited.

"And you always cure them?" House straightens her ponytail and shakes his head.

"No, sometimes they are too sick by the time we find out what's wrong so they die, or the disease it's incurable or chronic, so they die too or have to live with medication to reduce the symptoms." Rachel looks sad at the paper before attacking him with her doe eyes.

"But you save most of them, right?" House nods and she smiles, reassured. She returns her gaze to the paper and reads the last question, one that she'd had to think for herself. "And the patient you have now? How is he? What does he have?"

"Well… I can't give you names because that's illegal, but we still don't know what's making him ill. He has seizures, abdominal pain, his eyes are damaged and weight loss. Normally I would have said teniasis but tests turned negative and the guy's vegan, so not possible."

"What's vegan?"

"A person that doesn't eat anything that has to do with animals. Just fruits and vegetables."

"Oh. And tenaisis?" House snorts.

"Teniasis. It's a disease caused by a worm in your tummy. You can get it if you eat pork of beef that's infected with it."

"Yuck…" she makes a face and writes it down. A second later Chase, Masters, Gordon and Hans –the new members after Foreman and Taub left– enter the room. "Hi, Chase!" she bounces on her seat and waves.

"Rachel, hi! Give me five, Lil' bugger!" she giggles and stands on her chair to give the Australian the customary high five. "What're doin'?" as he circles the table to see what's written on the paper, Hans takes the results from Gordon's hands –who's watching Rachel with a slack-jawed look– and present's them to House.

"All negative, sir… I mean, House." She hastily corrects at his sour look.

"Then what the hell is it?" he hears a gasp at his side and all look at the little girl that's looking at House with big eyes and her hands over her mouth.

"You said a bad word!" she points at him and hides her smirk behind her other hand. "I'm gonna tell Mommy!" House seems frightened –fact that shocks Gordon and Hans into next life– for a second before smirking.

"If you do she's punish me and I won't be able to make cookies this weekend." He pouts and Rachel gasps again, horrified this time, before shaking her head vigorously.

"No, no! You have to make cookies! I won't tell Mommy!" House holds his sigh of relief and nods satisfied.

He turns to the rest of his team; Masters is struggling between uncomfortable and amused, Gordon is playing mental Ping-Pong between House and Rachel, Hans completely confused and Chase is snickering from his place behind Rachel.

"Umm…"

"You guys really don't know who she is, do you?" both shake their heads. "This is Rachel Cuddy, Lisa's daughter."

"Lisa?"

"Dean Cuddy." Supplies Chase. Gordon finally breaks out of his stupor and turns to the girl.

"And you're here because…"

"Because we were supposed to go shopping for a costume but the patient got sick, so Mommy brought me here so I could do my report!" she waves the sheet in the air and puts it away. Gordon nods and shifts his gaze to House.

"So… now what do we do?"

"All negative?" they all nod. He get's up and paces. Rachel follows his movements with her eyes. "What looks like teniasis but isn't teniasis?"

"Teniasis." Chase rubs his forehead and leans on the chair.

"Everybody lies!" they turn to Rachel, who's grinning at House expectantly.

"I'm very proud of you, but that doesn't really help. We already ruled out that he lied and the test turned out negative."

"But tests can lie too, right? And it's impossible for somebody to not eat meat. I would die without a steak." She nods, satisfied and looks at everybody in the room.

"A false negative?"

"That's not very common."

"It's not impossible either…" they look at each other before looking at House, who is staring at Rachel with a look of pride and admiration on his eyes.

"I'm so proud of you, kiddo." He takes his cane. "Rerun the tests. Rachel, with me." He smirks at her. "You've earned yourself an ice-cream."
