Varius was in the corridor that had a bunch of suits of armour. Goodness knows why the founders of this castle thought 'hm let's have a bunch of metal knights lined up against these walls!'. Varius would bet money on it being Rowena. She would be awkward like that.

Anyway, Varius had opened his book of Hogwarts, a History and turned to his page where he noticed a loose piece of parchment. Apparently some alumni students had placed lickable licorice inside some armour and or course Varius had to investigate!!!
