Well, not for certain, but I entertained the thought and now here he is! I call him Trixster!
This is a scene that I kind of depicted from a story that I might be writing about him. Basically he's following Twilight and trying to show her a book that he's written on the ethics of magical showmanship. As you can see, Twilight is not very willing to give him a chance!
Also for your viewing pleasure, the book cover in all its glory!
