After WWII (Wizarding War II), who went to teach each one of the classes?
Minerva Mcgonagall became the Headmistress, and IIRC the DADA teacher is no longer present (having been replaced by Voldemort to Dark Magic classes) so who takes her and the other teachers' places when the whole ordeal is over?
Update: This asks about all of the teachers including DADA, and is more broad as a question than a single teacher. For instance Professor Trelawney is sacked by Umbridge, but does she resume upon the rehashing of the school staff?
