Snape discovered the second petrified person the day before Christmas break, which was rather unfortunate for Mr. Finch-Fletchley. It turned out Justin had frozen in the perfect position to be dressed up as the lead for Swan Lake. He was promptly placed on display in the middle of the Great Hall, with Percy-in green plaid tights-serving as the prince.
"Not that I don't like the display, Sev, but is the Swan Princess supposed to be wearing a cheese wedge hat?" Remus asked curiously.
Sirius blinked slowly. "I'm beginning to see a pattern here..."
"Which is?" Snape asked silkily.
"All the victim's are...GEEKS! Obviously the perpetrator only attacks the socially impaired!"
Two hands slapped Padfoot on the back of the head. "Remmy!"
"Only you would think of something like that, Siri," Remus sighed.
"I have a better idea," Severus added. "Perhaps all the victim's were found wearing cheese wedges?"
"Socially impaired cheese wedges?" Sirius was absurdly hopeful. He put on his best puppy expression.
"Will it shut you up?"
"Temporarily."
"Then yes, fine! They were all wearing socially impaired hats!" Sirius gave a triumphant yowl and hugged Severus.
