Hermione has been having trouble with her spells lately. Her wand isn't working right for some reason. Luckily, a professah (You) stopped and noticed she was having an issue. You're kind enough to offer to tutor her, IF she does something for you, like stroke your wand to completion. (Note: This is video has a few giggles in it, but I genuinely couldn't help it! All the HP puns were going to me head! Enjoy the rare sweet kristie treat!:P)
