#(arguably?)

So, the patient comes in with nausea, vomiting and weight loss, and the ER healer figures it's some kind of flu-type illness and gives the patient a Lesser Restoration. It doesn't work, which is weird, because Lesser Restoration should eliminate any disease.

So they call in House, who sends his team to get a patient history. And in the patient history, Cameron finds out that the patient recently pissed off a wizard, and when she mentions that to House, House is like "the wizard obviously cursed him. Do Remove Curse."

(While this is going on, the B plot is Wilson is having an ethical dilemma over whether he should help treat a vampire who kills people. House is on the side of 'we treat everyone, regardless of how many people they kill', whereas Wilson is like 'if I save this person's life am I dooming their future victims?')

Back to Cameron, Chase and Foreman - they're telling the patient they're gonna do Remove Curse, and the patient doesn't want them to, but he won't tell them why. Cameron doesn't want to cast the spell if the patient doesn't want it, but Chase is like "that's probably just the curse talking," and casts it anyway. But oh no! That makes the patient worse, and he goes into death saves. Foreman casts Spare the Dying and stabilises the patient, but he's still unconscious and can't answer any more questions.

House is like "you idiots, why didn't you tell me he didn't want the curse removed?" and sends them to break into the patient's house. They find a bunch of calendars that very clearly mark each full moon, and it turns out that the patient had lycanthropy. Remove Curse removed his lycanthropy, turning him back into a regular human - lowering his hit point maximum and his constitution, making his other condition worse. So maybe the patient was under the effect of Lycanthropy and a wizard's curse? Cameron tries Remove Curse again, and nothing happens. The patient is still unconscious and needs Spare the Dying to be cast on him pretty regularly.

So now obviously the answer is to get the patient re-infected with lycanthropy, because otherwise he's going to be stuck in a loop of unconsciousness -> death saves -> spare the dying -> unconsciousness.

So House asks Foreman to go track down another werewolf to bring in to bite the patient, and that's a whole thing. While that's happening, Cameron is trying to figure out what the wizard did, because it had to be something, right? No one gets into a fight with a wizard and then falls ill a day later and those two things not be related. And she's running a bunch of tests for various poisons or spells and they're all coming up negative.

Foreman brings in a werewolf. When the werewolf sees that the patient isn't conscious and can't actively consent to being bitten, they don't want to go through with it. House bullies them into it by implying that the patient dying would be their fault if they don't.

So the patient wakes up and is a werewolf again, but then the second werewolf gets sick too with all the same symptoms. Whatever it is contagious, but no one else feels sick, so it's passed on by bite only.

Cameron finally tracks down the wizard and brings them in like "you need to dispell whatever you cast" and the wizard is insisting they didn't cast anything. Cameron asks what the fight was even about in the first place, and the wizard tells her that when the patient was in his wolf form, he lost control, broke into the wizard's garden, and ate their pet rabbits. Cameron asks if the pet rabbits had the same symptoms the patient first exhibited, and the wizard confirmed they did. So then they're looking for something contagious that passes from animals to humanoids via the consumption of meat that is neither a disease nor a curse nor poison.

Cut back to House and Wilson, who are still talking about whether Wilson should treat this vampire. And House is saying something like "we treat bad people all the time, just because this one is a parasite doesn't mean -" and stops mid-sentence and sprints to the patient's room (which is now housing both werewolves) and announces that the first patient got sick with intestinal worms after eating the rabbit, which got passed onto the second werewolf when they bit him. Parasites aren't affected by Remove Curse or Lesser Restoration, which is why their earlier efforts didn't do anything. Now they know what it is, they can brew up some potions and heal them both. House makes a few insensitive jokes about them being werewolves and telling them they should go to a vet's next time, and then limps away.

Cut back to Wilson, who has offered up his own blood to the vampire to try and prevent them killing anyone else when they get hungry.
