I don't know how Chase and Cameron got assigned to check out Fran's house together, but they did. Chase wonders whether they should feed Harrington (who's still hanging out on the top of Fran's dresser) while they're there, but Cameron says his food bowl is full, and Cameron's heart is black and cold anyway, so she probably feasts on the blood of adorable kittens. She works for all of three seconds before asking Chase what he thinks of what Foreman said about their "relationship" interfering with work. Chase sarcastically says that Foreman was totally right, and he only agreed with Cameron so she'd "do" him in "some old lady's house." "Well played," Cameron says, her mouth turning up into what is probably supposed to be a seductive smirk. She shoves Chase onto the bed while he weakly protests that they should be working. She doesn't think they need to look for toxins there, since they both think Fran has a brain tumor. And it's not like they've ever been surprised by cases before where the culprit turned out to be environmental, right? Oh, except for at least one case per season. I don't approve of Foreman's need to bring Chase and Cameron's relationship up all the time in front of colleagues and whoever else might be wandering the PPTH halls, but he does have a point that it's interfering with their work. Chase doesn't want to have sex in front of Harrington, though. Neither did Fran. Is Harrington like the Bush's Baked Beans dog or something? Who cares if he's watching? He can't tell anyone what he saw or use his cell phone to take a secret video of it to post on the internets. "Haven't you had anybody watch before?" Cameron asks, like she has. Please. You know, I'm starting to think Cameron's never had sex before, the way she's acting.
On the plane, the Korean is still barfing. The blonde girl watches him puke over the armrest until Cuddy finally wises up and closes the drapes. Meanwhile, those disapproving passengers from before can't take the puking and the smell anymore, and they abandon first class to sit with the peasants. I wonder if they'll sue the airline for this, like that guy who had to sit next to a corpse during a long flight after a woman suddenly died in the economy section. He was angry because they allowed the dead woman's family to come up and grieve, and their wailing interrupted his enjoyment of the in-flight entertainment and kept him awake. The blonde again confronts House about the Korean, scared that Cuddy was right about a possible deadly pandemic after all. House just tells her to turn and face a different direction, because his amazing doctor skills tell him she's about to barf and he'd rather she not do it on him. Although, honestly, even barf would be an improvement over that horrible yellow Hawaiian shirt he's wearing. Of course, House is right, and the blonde turns and barfs. How did he know that she was about to barf when she didn't? The thing about barfing is that your body takes, like, ten minutes to prepare itself before it actually does it. So you usually know it's on its way. Unless you're in bed with food poisoning and feeling like that all the time, in which case the barf surprises you and you have to put your hand over your mouth and run to the bathroom and even then you don't quite make it. The girl pukes up something bright yellow, and even manages to get some on House's shoes despite his efforts to remain untouched. Cuddy's barf alarm goes off in first class and she runs back, but before she can point to this as a sign that she's right about the Korean having something contagious, House says that it's natural for humans to throw up if they smell or see someone else doing it. But that's not what's happening here, as Cuddy lifts the back of the blonde girl's shirt and sees that she has a distinctive rash. "I wasn't expecting that," House has to admit.
