Private message to Penelope Clearwater

I saw from the journals that you were forced to assert the Head Girl's authority. I have no doubt it was regrettable (or perhaps even unpleasant) that you had to take that step, but applaud you for doing what must be done. I trust you are well? None of the aftereffects that Miss Professor Carrow mentioned might occur to those who use that curse? But no, I know I needn't even ask; I trust your character is resolute enough to withstand the trial.

I have no doubt that Professor McGonagall is entirely satisfied with her choice of you as Head Girl, as you have demonstrated that you are more than equal to the challenge.
