Chase: "Parents aren't doing or dosing this kid."
House: "How would you know that? Kid can’t talk. Why do you think I took this case? He's not going to give away the ending."
―Lines in the Sand

Lines in the Sand is a 3rd season episode of House which first aired on September 26, 2006. House is drawn to the case of an autistic boy, apparently only for the reason that the patient can’t communicate well enough to give House any clues as to his condition. However, it’s House’s social skills that are soon at issue when he insists his blood-stained carpet be returned to his office. Meanwhile, a 17 year-old patient starts finding House irresistible.


A 10 year-old autistic boy named Adam is communicating with his father using pictograms. He quickly tires of it and starts drawing wavy lines with chalk. His parents start arguing about his condition and habits when Adam starts coughing, then screaming. He is taken to Princeton-Plainsboro for examination.

House takes the case, ignoring remarks from Foreman that the patient is screaming because of his autism. Cameron is astounded that House believes the parents when they say something is wrong, but House notes that his parents have been caring for him constantly and this is the first time that they've brought him to the hospital. He orders tests and an environmental scan. He jokes about how difficult it will be to perform a scan on an autistic young boy.

House storms to Cuddy to demand she put the carpet—stained with his blood from the attack on his life —back in his office. House tells her he won't use his office until the carpet is returned. When Cuddy resists, he starts shouting "Attica! Attica!", but Cuddy remains unmoved.

When Foreman goes to test the patient, his father tells them to wait until Adam finishes a level on his video game. Foreman, impatient, attempts to yank Adam's video game console out of his hands, causing the latter to go wild. Adam is restrained in order to get him into the scanner.

Chase and Cameron go to search the patient's house. They discuss why the parents would give up their lives to care for their son.

The tests come back normal, and House is working in the clinic with his team to stay out of his office in order to defy Cuddy. Cuddy comes in and tells House his behavior isn't going to make her change her mind about the blood-stained carpet. House orders his team to take a fecal smear. However, as the team goes to do the fecal smear, Adam starts suffer from a pleural effusion.

House retreats to Wilson's office to do his differential, but as he orders an echocardiogram and antibiotics, Wilson opens the door to find them there. He stops House from playing with his things. House asks why Wilson never throws anything out, and then drops a thank-you gift from a child patient into the trash.

Once again, the patient is frantic while Foreman performs the echocardiogram. House retreats to a conference room. Foreman finds and confirms that the patient has a conduction abnormality. At that moment, Cameron realizes House is not just playing power games, actually does want his bloodstained carpet back. Cuddy enters the conference room and throws the team out. House orders Foreman to do a lung biopsy, but Foreman tricks Wilson into doing it, although Wilson says a lymph node biopsy under the arm is a better idea. Once again, the patient is frantic during the procedure. House manages to anesthetize the patient by taking some of the anesthetic himself. The patient follows suit and is knocked out. The parents are impressed. House says it was only the child imitating him.

House, too, wonders why the parents have invested so much into their child. He expresses envy about how the child doesn't have to worry about social graces. The lymph node biopsy is negative; however, the cells biopsied are liver cells.

House and the team retire into Wilson's office. Cameron thinks the misplaced liver cells might be a sign of cancer. If the cells were damaged, they could travel through the body. However, the patient's liver tests are normal. The only explanation seems to be cirrhosis, but the only way Adam could've gotten cirrhosis would've been his parents giving their son alcohol. House thinks the parents don't want to deal with their son anymore and orders a liver biopsy. House tells Cameron his parents love him unconditionally.

House takes up residence in Cuddy's office. House asks Foreman for the results of the stool sample, but it's normal. Cuddy enters her office and confronts House, but gets him to leave when a phone call informs them that the patient has been taken to the cardiac intensive care unit.

They manage to stabilize the patient, but now the patient's liver is failing. House suspects that Adam might have eaten something that is causing the liver failure. He orders Foreman to take samples from the patient's house.

Foreman finds jimson weed, which would explain the symptoms except for the screaming. However, if the patient doesn't have jimson weed poisoning, the treatment for it will make him worse. Testing him will take more time than the patient is likely to live. House goes to the patient and asks him what he ate, while holding up the pictures he uses to communicate. The patient grabs the picture of the sandbox and, at the same moment, his eye rotates backwards in its socket.

House calls for the team to meet in the chapel. The team begins discussing the possibilities of why Adam's eye rolled back, which is consistent with jimson weed. Foreman thinks it might be a metastasized microtumor, but if he's right, it would mean removing the patient's eye.

However, just before the operation, House realizes that the squiggly lines the patient has been drawing on his chalkboard are worms in his eye—the only way the patient could communicate the symptom. House examines the patient’s vitreous humor and finds the worms. He has a parasitic infection from eating animal feces in his sandbox. The condition can be successfully treated.

Wilson tells Cuddy that House may have Asperger's syndrome, a mild form of autism. She doesn't believe him, but he tells her that House took this patient because he reminds him of himself. However, after he convinces Cuddy, he goes to House and tells him it was all a lie—he really is just a jerk. House realizes that the patient will never feel the happiness that normal people feel, and the parents' lack of enthusiasm is due to the fact that they will have to constantly care for the boy for the rest of his life. However, as the family is set to leave, the patient hands House his beloved PSP and makes direct eye contact with House. His parents are ecstatic, since he has never shown that level of emotional connection before.

House returns to his office and his old blood-stained carpet.

Major Events

  • House starts pestering Cuddy in an attempt to get his original carpet back.
  • Ali returns to the clinic once again.
  • To make Cuddy agree to his terms, House starts using the clinic, Wilson's office, and the conference room as places so that he and his staff can discuss their current case.
  • House and Cuddy clash over Ali, House's teenage stalker. Cuddy claims that she's stalking him while House thinks differently on the subject.
  • House finally confronts Ali and tells her that she has an infection which is affecting her judgement.
  • Cuddy gives in and House gets his old carpet back.

Clinic Patients

Avoiding his own office, House is faced with a bevy of inane cases.

The first patient brings in one of her rarely excreted feces for a doctor to look at.

The second patient came in because his serious back pain has gone away—he's feeling great.

The third patient is Ali, a 17-year-old girl had earlier been to the clinic with her father who thinks she has a common cold. House starts to examine her, and she takes off her top, exposing her breasts, ostensibly so that House can use his stethoscope. Foreman bursts in on them accidentally.

Cuddy confronts House about Ali (she's left 15 messages for him that day) and tells security to keep her out of the hospital. House doesn't think she's dangerous. He shouts "You can't stop our love!" although he makes it clear he isn't interested in her.

Later when House goes to the garage to go home, he finds Ali sitting on his motorcycle. They start talking about age of consent laws. He reminds her of their age difference—"over ten years". Cuddy catches them and makes Ali leave, threatening her with arrest if she catches her again. She warns House about Ali.

Cuddy tells House that Ali is locked in her office. House goes to see her to dissuade her from coming after him. He gives her a spiel from Casablanca. However, as he examines her face, he notices she has milky tears which indicate a fungal infection that is causing a lack of inhibition and judgment. In actuality, c. immitis never presents with these symptoms, and was an attempt to trick Ali into staying away. She accepts the explanation.

Zebra Factor 2/10

Baylisascaris is a common infection in humans and is ubiquitous in the environment. It can develop anywhere there are animal feces as it infects more than fifty different species. It is very easy to contract.

Trivia & Cultural References

  • House's comment "We'll always have Fresno" is a reference to the famous line "We'll always have Paris" from the 1942 classic film Casablanca.
  • The title is a common idiom [1] representing a point past which a person will not cross or after which advance would not be acceptable. It has several expressions in this episode:
    • House refuses to let his old carpet be removed, and Cuddy refuses to return it;
    • The patient keeps drawing lines to indicate his condition;
    • The patient contracts his disease in his sandbox;
    • House is seen in Wilson's office, drawing lines in Wilson's miniature zen sand garden;
    • House declines to sleep with Ali;
    • Ali points out the age of consent in New Jersey (18) is arbitrary compared to those in other places (such as Iceland, where the age is 14); [An error the episode makes is the NJ age of consent is actually 16.   Either the writers didn't want the complaints from viewers over making it realistic, or it was a purposeful mistake showing her possibly compromised mental faculties].
    • Cuddy bars Ali from the hospital premises;
    • Cuddy threatens to fire House, but when she does not, House reminds her that threats that aren't followed up on indicate weakness.
  • Attica is a reference to the Attica Correctional Facility, a prison in upstate New York that hosted a riot in 1971. House’s chant of “Attica” is from the film Dog Day Afternoon.
  • Zen is a school of Buddhism, native to China. The miniature sand garden in Wilson’s office were influenced by Zen.
  • "Mel's Diner" was the setting for a popular sitcom from the '70s and '80s, Alice.
  • House’s dialogue in his final scene with Ali is paraphrased from Casablanca, a 1942 film about two former lovers who re-meet years after she leaves him to join her older husband, who she has just learned has not died. The dialogue is taken from the scene where Humphrey Bogart convinces Ingrid Bergman to leave with her husband.
  • This episode is based on a real case from 2005. There, the patient was 7 and suffered similar symptoms before recovering.[2]
  • Upon discovering the jimson weed in the patient's back yard, Foreman suggests that he is "tripping on lucy in the sky with cubic zirconium." This is a reference to the Beatles song "Lucy in the Sky with Diamonds " which itself is believed (though denied by the writer, Lennon) to be a reference to the psychedelic drug, LSD .  
  • When House is playing PSP while laying in Adam's hospital bed, he appears to be playing Frogger: Helmet Chaos  
  • Wilson has framed posters for the films Vertigo and Touch of Evil on his office walls.
  • Wilson describes Asperger Syndrome as a "mild and rare form of autism", however rates of Asperger Syndrome are estimated by to be greater than 1 in 100 people.



Cuddy:  "She's dangerous!"
House: "She's not dangerous."
Cuddy: "She's pretty."
House: "She's pretty."
Cuddy: "Men are stupid."'
House: "I'm with you so far."
Cuddy: "I'm notifying security."
House: "Oh, give her a break. She's not dangerous! She's...insightful. YOU CAN'T STOP OUR LOVE!"

House: If you remove this kid’s eye, he’ll only be half as good at not making eye contact.

House: "(Bursts into operating room) Hey! Don't touch his eye!"
Dr. Simpson: "This is an appendectomy."
House: "(Taken aback but unable to admit his error) Like I said, don't touch his eye."
— Trying to stop surgery on the patient

Cameron: "Is it so wrong for them to want to have a normal child? It's normal to want to be normal.
House: "Spoken like a true Circle Queen.  See, skinny, socially-privileged white people get to draw this neat little circle and everyone inside the circle is normal—and everyone outside the circle should be beaten, broken and reset, so they can be brought into the circle.  Failing that, they should be institutionalized, or worse, pitied."
Dr. Cameron: "So, it's wrong to feel sorry for this little boy?" (referring to their severely autistic patient)
House: "Why would you feel sorry for someone who gets to opt out of the inane courteous formalities, which are utterly meaningless, insincere, and therefore, degrading? This kid doesn't have to pretend to be interested in your back pain, or your excretions, or your grandma's itchy place. Can you imagine how liberating it would be to live a life free of all the mind-numbing social niceties? I don't pity this kid...I envy him."
