The Two Wicked Hufflepuffs - or So I Believe...

I will soon be posting a new essay, inspired in part by previous held beliefs about a certain character introduced in Harry Potter and the Half-Blood Prince, and another certain (major) character introduced in Harry Potter and the Order of the Phoenix. The other part of inspiration for this upcoming essay is from listening to The Leaky Cauldron's archived PotterCast episode #142. Can you guess the two characters I am writing about?

Hepzibah Smith

and

Dolores Umbridge.

Dun Dun DUN!!!
