Harry Potter and the Chamber of Secrets - Spell Did the Wrong Thing?
During the Dueling Club, while Draco and Harry are dueling, Harry does the Rictosempra spell (the tickling spell) but Draco shows no sign of being tickled (ie laughing/smiling) but instead is lifted up and slammed back down again? Why would he be thrown up and back down if it is a tickling spell? huh...
rictumsempra is the tickling spell that Harry uses in the book. I've also asked J.K.Rowling about it myself. And by the way Expecto Patronum is her favorite spell..
