E.F.T

This episode puts a spin on the "Chlois theory" as a magic spell turns Chloe into Lois... literally.- Cassidy Freeman (Tess) and Sam Witwer (Davis) do not appear in this episode.
The episode's guest is a character named "Cassie" whose father taught her about sorcery before he passed away. We're wondering if "Cassie" might be a substitute name for the DC Comics magician character Zatanna, much like "Melissa" was substituted for "Maxima" in initial leaks. Many Silver Age DC Comics books
told the tale of Zatanna looking for her father, Zatara. Interesting trivia: Zatara first appeared in the same comic book that introduced Superman - Action Comics #1!- Cassie tries to get Oliver to believe in witchcraft, and comes to him for help. Apparently Lex had obtained an item before he disappeared that she would like to obtain. She offers to give Oliver his "deepest desire" if he helps her.
