The Cottages perform the test on Jessica, who complains of being thirsty, which means a seizure or respiratory arrest is right around the corner. They're too busy making bets on which one of them is going to get fired to take much notice of Jessica until she starts telling everyone off and trying to remove all the medical tubing. As we go to commercial, Jessica's screaming obscenities, which is pretty cool.
The Cottages sort of apologize to Jessica's mom for inducing the hypoglycemia that made her daughter get all awesome. Jessica's mom is just a little bit annoyed at the fact that instead of paying attention to her daughter, the doctors were "bickering" and "placing bets." Cameron gives the apology another go, hoping a sensitive woman's touch will smooth things over, but Mom tells her to "save [her] pathetic insincerity for [her] boyfriend." Apparently, hypoglycemia crankiness is contagious. Chase, who's standing behind Mom, makes a hilarious "oh, SNAP!" eyebrow raise as he wonders if having the smackdown laid upon one by patient relatives is one of the criteria for getting fired. House limps up to defend the Cottages, saying that while Cameron is pathetic, she is also very sincere, and also that the lab results show that Jessica's bitchiness was not caused by the test. They don't know exactly what did cause it yet, but it's not something that can be cured by simple diet or exercise.
Back to the drawing (white)board! House points out that now would be a great time for one of the Cottages to come forth with a brilliant idea about what Jessica's problem is, because he figures that as long as everyone's thinking it, he might as well just say it. And also because he's an asshole. Chase suggests a blood clot, which Cameron shoots down for being more likely to cause a stroke than a heart attack. "No, you're wrong," Chase says curtly. And then they bicker back and forth while Foreman rolls his eyes and House watches with glee. Cameron wins the argument after forcing Chase to say that their ten-year-old patient's blood clots could have been caused by liposuction, which is ridiculous and undermines anything non-ridiculous Chase said before that. Even House won't roll with that. "Thank you," says Cameron, who is much cooler when she's feisty. House suggests that diet pills could have caused Jessica's problems, and assigns Chase and Cameron to give Jessica blood-thinning agents for the clots they don't know for sure she has, and Foreman to find Jessica's diet pills.
