QUOTE : Surely even Snape-hating Gryffindors enjoyed the moment Snape turned to face Umbridge. Rowling carefully unites the sentiments of Slytherins, Gryffindors, and the reader behind Snape for this scene: even Umbridge can find no fault with Snape’s academic standards. His classroom manner has indisputably caused damage, but his students have put in the labor. One way or another, together, he and the students have created something unassailable by this intruder.
