Harry Potter and the Violation of the Geneva Convention
Hermione: If Voldemort likes the good ole’ days so much, why don’t we bring them back? Old society, old war tricks
Hermione, putting on a gas mask: New plan. We take them out with consumption and mustard gas
Hermione, to Voldemort: Did you know, historically, a majority of war deaths come from disease?
Harry: What if we gave them all smallpox
Hermione: HARRY NO! We already eradicated it once, let’s not make the world do it again
Harry: Oh yeah, I guess you’re right
Hermione: Now tuberculosis, on the other hand…
Circa Seventh Book
Hermione: Has the wizarding world discovered vaccines?
Ron: A wax what?
Harry: Hermione, we cant take out the death eaters with a genetically magicked disease
Hermione: No I know that. Of course I know that.
*Uncomfortably long silence*
Important question: Has the wizarding world discovered vaccines and is Hogwarts vaccinated?
