Ummm...why didn't Harry march directly from battle into Draco's compartment and hex the living shit out of the ferret and his cronies then go and breast-beat with the girls?
The scene between Dumbles and Scrimgoeur was excellent, especially with Dumbles still only thinking in terms of his own agenda and manipulations.
Glad the Centaurs are happy, and with Harry's level of magic, Hogwarts will be hip-deep in foals in no time.
All over - a fine chapter. I am keenly awaiting the next.
