I love this show but I simply hated this episode. I know we're supposed to think House is a jerk but he was truly evil this time.
He performed invasive tests on a teenager without her consent. And he did so just so he could find a cure for his own pain. His actions where not only illegal, they were immoral. I don't know if they exaggerate this aspect of the show but seeing minors being abused by doctors isn't my idea of entertainment.
Don't do plot lines with unwilling minors as the patient of the week, House writing staff, it's just too disturbing.
