When Cutty entered the Charms classroom he was greeted by the sight of drooling Fuller. This delighted him. One, because it was disgusting...at least a lil bit and two, because it meant that Fuller had fallen asleep and when he was woken up he'd be in that groggy state where people often said weird things and their hair was all about.

Cutty would've been happy to have done the work of waking their Charms Professor, but it seems that Maroon had taken on the duty himself. Excellent. Time to take a seat.
