Taystee warns the girls not to mess around with "that voodoo shit", warning them that they might end up like "Cedric Diggory". When the girls don't know who "Cedric Diggory" is, Taystee and Poussey explain that he is a character from 'Harry Potter'.
In this book, fourteen year old Harry Potter goes back to Hogwarts Wizardry School for his fourth year and, a series of adventures and mishaps. Harry is maturing as a wizard-in-training and is still surrounded by his best friends, Hermione and Ron. Someone has put Harry's name into the goblet of fire, an allegorical "hat" for the Triwizard Tournament (a three school contest for the very best wizarding students to compete in) that was meant for much older and more mature students. To compound his troubles, Harry and his best friend Ron have a major misunderstanding and Harry is stalked by a tabloid newspaper columnist who seems determined to destroy Harry, the school's leader, Dumbledore, and all of Hogwarts.
