The QE men are nearly finished with their... *ahem* task. However, until that time I will remind you once again to steer away from Professor Snape's chambers. To make sure no one walks in accidentally and gets hit in the crossfire, I've put up several security charms that only I and your other professors (minus Snape) know how to get past. Thus anyone who touches the door to his chambers without taking the charms down first will be turned into Gendo Ikari. That is all.
