On one end, Professor McGonagall was more silent with me. Indicating her disappointment, but also confusion. Professor Slughorn and Snape were beside themselves. Both individuals have some ties into the dark; or are practitioners, like Professor Snape was. For them to see someone use dark magic, for healing of all things, was a small stepping stone for the world to know the truth of dark magic. Not what the Ministry deemed was necessary for a citizen to know.
