Thank you for this story. I particularly like the way you've written Bill and Tonks, but you've done a good job with Snape as well. It's also an entirely original plot, I've never heard of a storyline like this, good job! :)

Actually, disciplining students is essential...how else do you keep a class in order and safe?
No real teacher would say "never do class control"...they would ask for judgement, but blowing up a cauldron for fun?
Expel her for safety reasons...

nice

Quite interesting. Nice characterization of Tonks.
