Swan will appear in this season's 17th episode, "Hex," as Zatanna, a magician who grants birthday girl Chloe a wish. Having been through the wringer ever since Brainiac mind-boinked her and Doomsday crashed her wedding day, Chloe expresses a desire to lead the comparatively mild-mannered life of Lois Lane. Voilà! Chloe magically inhabits Lois' (and thus Erica Durance's) body for the bulk of the hour.***Clark is also granted a wish. But what could he possibly want for?This will be interesting. It's great to see they are taking a lesser known character (lesser known to the non-comic book reader) and bringing them to life. It should be interesting to see how the producers will decide to dress her. Will they go with the classic look Zatanna is famous for?
