Plot

After a wild night out, a teenage girl named Jordan(Anna Attanasio) is brought to Princeton Plainsboro with severely swollen appendages. The team must work to diagnose Jordan, who is less than honest about what happened the night she fell ill. House suspects she is suffering from rhabdo

 and the fall caused crushed muscles which released toxins that caused swollen joints. But the CT shows no signs of trauma, so House goes in and gets Jordan to pretend to play the drums. Her hands are very weak. House notes that her chart shows low potassium, and rhabdo elevates potassium levels, meaning her potassium had to be extremely low the previous night. This means she can't have climbed stairs, meaning there was no fall. House says something else is causing her low potassium and rhabdo.

Meanwhile, Cuddy, Wilson and House spend a weekend away from the hospital to attend a medical conference. During an 80s

 party at the convention, House musters up the courage to reveal his feelings to Cuddy. She leaves him in a haste and lets him know through Wilson that now that she is a mom she needs someone reliable. When House in turn offers Cuddy to babysit he finds out that she is dating the private investigator Lucas (Michael Weston

Jordan's friend, Phoebe, tells Cameron and Chase what they did the previous night, stating they followed comic book creator Jeffrey Keener (Marcus Giamatti

. House notes that since her blood pressure dropped during the barium swallow, it can't be a chronic condition. Foreman notes that this leaves just infections and toxins.

As Jordan's condition worsens, she becomes unable to distinguish fact from fiction. Foreman finds this is caused by a bleed in her brain that's affecting her thalamus

 causing her to lie. Phoebe tells Foreman that he's been told all the places they went. She says the only time they weren't together was when Jordan went to get ice. However, Phoebe only woke when Jordan returned, so the team has no idea what Jordan really did, or how long she was gone for. CCTV tapes show she was gone for only five minutes, and she returned from her trip holding Keener's journal. Cameron and Chase go to Keener's room and ask to search his room for toxins, but he insists she never arrived at his room. This causes Cameron to suspect that Jordan may have been drugged by roofies

She soon starts to bleed behind her kidneys, so Foreman gives her blood transfusions. Cameron notices that this is similar to a toxic reaction, so they need to find out what toxin is causing it. Cameron suggests drugging her with amobarbital

 overdose. Wilson plans to give a speech about the incident, although it may severely harm his career. However, House drugs Wilson and makes his speech during the convention in another person's name. While arguing about this, House has an epiphany about Jordan's condition.

It turns out that Jordan has vibrio vulnificus caused by the vibrio in the oysters Jordan had the previous night. She has hemochromatosis, which gave her a unique susceptibility to vibrio, which was what caused her swollen joints. However, this got attributed to bulimia so she got supplements that had iron in them. The iron stressed her liver, causing the bleeding. This lead to more blood transfusions, giving her more blood, causing even more bleeding. The team starts Jordan on high-dose ceftazidime for the vibrio and chelate for the hemochromatosis. Jordan also admits that she never plucked up the courage to knock on Keener's door, so she left his notebook on his doormat. Keener never lied. Later, Wilson also admits that it was irrational to sacrifice his career because of his remorse and thanks House for being a good friend.
