I wondered about this. In DH, the house elves were fighting in the
kitchen. But, didn't Hermione knit clothing for the house elves,
therefore making them free? Did Hogwarts then do without the house
elves or just go out and get more? Didn't anyone know that it was
Hermione that was freeing them? Shouldn't she have gotten into trouble
for making the house elves free?
