I find it funny that they wern't the least suspicious that the nurse is also called Medusa.
It's like "dam that witch Medusa is evil" *nurse Medusa walks in* "oh, good morning nurse Medusa...waitaminute..." O.o
And her bangs should at least be a bit...
I mentioned before though, I prefer her gentle side as nurse Medusa (and she does look very cute without the evil glare)
