If you struggled through the classically complex and layered story of the last four seasons, you're not alone. It was, as Mrs Sheffield has it, "more twisty-turny than my graduate teaching assistant's insides after my AP Honours' Intestinal Inversion lecture and practicuum."  So Dr. Charles Tucket, who you may remember from another hiatus episode, The Oz 8000 Biosphere: Portrait of a Refuge, has been unthawed once again to provide some much-needed and hopefully not teeth-grittingly dull exposition and explanation. Good luck. Take notes. You've been listening to: Kyle Jones as the tour guide and Narrator Two. Chris Nadolny Gourley as your Narrator,  and David S Dear as Dr. Charlie Tucket. Our music is by John Faley; our artwork by Lucas Elliott. Sarah Golding is the dialogue editor, and Oliver Morris is our sound designer. Oz 9 is written by Shannon Perry.
