I don't know if this has been brought up before (I haven't read posts 
for awhile), but do we know what went on during the Slytherin's 
Defence Against the Dark Arts classes in the fifth book? If she was 
secretly working for Voldemort(which I believe she was), isn't 
possilbe that she taught the Slytherin's the dark arts in her 
classes? Perhaps she was building up her own army whilst Harry and 
others built up Dumbledore's army. Any ideas on this?
