Refreshment and Goodies Table
Derek had been skulking around the dance floor for most of the dance, keeping an eye out for any students that were dressed or acting inappropriately (he'd come across one couple already with their hands in each others' pants and had given a very loud speech about the importance of contraceptives). In between, he'd been tugging at his 'costume' - he'd gone to the library and found a book on Greek mythology and done his best to engineer something to suit - to try and keep it in place. Turned out his sticking charms needed some work.
Satisfied with his terror spree for the moment, and feeling rather parched, he went to the refreshment table. He avoided the punch he knew was spiked (that was a time honored tradition and while he'd warned the younger ones away from it, he let them have their fun, sure that the hangovers the next morning would be lesson enough to most of them) and instead went for the pumpkin juice and a cupcake, unwrapping it and taking a huge bite. Mm. Chocolate. Definitely improved things.
