"Thirteen&amp;#039;s friend Darien, who she met during her stay in prison, arrives at her apartment, having sustained a knife wound. Darien is afraid that the cops will be in pursuit and Thirteen promises that she will not take her to a hospital. Darien explains that her associate Andre stabbed her as a distraction during a police raid, and though she has suffered no organ damage, Thirteen detects a problem with her friend&amp;#039;s blood pressure. House visits the clinical testing lab and learns that the experimental drug he has been taking is a poison that causes tumours. Scanning his leg, House discovers that he has indeed developed three small tumours. Meanwhile, Taub is informed by his nurse girlfriend Ruby that she has fallen pregnant. Back at her apartment, Thirteen calls Chase, asking him to retrieve an ultra-sound machine from the hospital. Chase arrives with the portable instrument, but demands to know what is going on and discovers the wounded Darien. Thirteen admits that she was briefly jailed and that she euthanised her brother, which shocks Chase. The pair carefully scan Darien - since she has hepatitis C - and notice a mass in her arm that is blocking the blood flow.  Taub visits a strip-club with Foreman in an attempt to distract himself from Ruby&amp;#039;s pregnancy, but is unable to relax. While receiving a lap dance, Taub notices that his stripper has an asymmetrical mole which could be cancerous, but his attempts to inspect it lead to a bouncer kicking him out of the club. Meanwhile, House scrubs down his bathroom and prepares to perform surgery on his own leg. With great pain and effort, he is able to remove one tumour, but is unable to continue. When a sleeping Wilson does not return his calls, and with his team busy, House is forced to call Cuddy for help. Thirteen suspects that Darien&amp;#039;s body has used up all the clotting factors to deal with her stab wound and, fearing that her friend could begin bleeding internally, sends Chase to the hospital to pick up medication. As Chase departs, Thirteen finds Darien experiencing a hallucination in which a young man with a gun is himself shot in the head. Chase returns with the clotting factor, but Thirteen tells him that he will need to return to the hospital to collect more in order to stop the brain bleed that is causing Darien&amp;#039;s hallucinations. As Darien&amp;#039;s conditions worsens, Chase insists on taking her to a hospital. Thirteen stands in his way, but Chase throws her to the floor after a brief scuffle and takes Darien by force.  Meanwhile, Cuddy finds a helpless House in his bloodied bath-tub. Chastising him for his foolish actions, she refuses to complete the surgery and insists on taking him to a hospital. Chase, Thirteen and Darien also hit the road, with Chase promising to treat Darien under a false name to divert suspicion. When Thirteen questions her friend about her hallucination, Darien reveals she used to be a cop and that she was forced to shoot an armed 19-year-old dead in the line of duty, with her lingering guilt leading her to abuse drugs. Arriving at the hospital, Darien undergoes tests, but Chase tells an angry Thirteen that she was so intent on keeping her word because she used another similar promise to justify euthanising her brother. A scan of Darien&amp;#039;s brain shows no sign of a bleed, but the patient develops a fever and subsequently lapses into a coma. House has also arrived at the hospital and Thirteen and Chase contact their boss, unaware of his condition. An ailing House advises them over the phone to look into Darien&amp;#039;s past in order to determine how long she has been abusing drugs and so learn the length of her Hep C exposure.  Outside the strip club, Taub approaches his dancer to talk about her mole, but she is convinced that he has seedier intentions and pulls a gun. A terrified Taub fears for his life, but the stripper eventually drives off, leaving him alone. Back at the hospital, as they research Darien&amp;#039;s past, Chase apologises for hurting Thirteen in their fight, but she tells him that he was right about everything. They discover that Darien&amp;#039;s traumatic shooting only occurred in 2008, implying that she has only had Hep C for a few years. Since she has been on medication for a chronic form of the disease, they finally realise that a parasite sped up Darien&amp;#039;s liver damage, with the stab wound allowing it to spread to her blood stream. As he is taken into surgery, House asks Cuddy to accompany him, claiming that he does not trust the surgeon, and she agrees to stay. Meanwhile, having received treatment for her parasite, Darien wakes up, but finds herself handcuffed to a hospital bed. Thirteen apologises for being forced to disclose her friend&amp;#039;s real identity, but a bitter Darien lashes out, telling Thirteen that she never really considered her a friend.  As morning dawns, Taub arrives at the hospital and tells Ruby that he had a realisation during his near-death experience - he wants to help raise the baby. Alone with Chase, Thirteen worries that she will become haunted like Darien after killing her brother, but he offers to talk her through her trauma. House&amp;#039;s team examine new cases, but realise that their boss is missing. Post-surgery, House wakes up to find Cuddy gone and Wilson at his bedside. A stubborn House initially refuses his friend&amp;#039;s help when he tries to leave his bed, but is unable to walk. As Wilson helps House to the toilet, he tells him that he cannot continue on his current self-destructive path, and House finally admits: &amp;quot;I know.&amp;quot; What did you make of this week&amp;#039;s House?
