Theory:Doctor Who audio discontinuity and plot holes/Colditz


 * Ace decides to start calling herself by her surname, "McShane". However, that was only Ace's name in the Virgin New Adventures. According to the original television series and the BBC Books, Ace's name is 'Dorothy Gale'. And Shadow of the Scourge was deliberately stated as taking place in an alternate universe, meaning that the Big Finish Audios and Virgin New Adventures do not co-exist in one reality.
 * Her last name is not given on TV. And Big Finish never stated that "Shadow of the Scourge" is an alternate universe, merely that the "side steps" were in continuity with the novels/comics so required more knowledge of media other than the TV and audio themselves. Later audios have established more continuity links with New Adventures, and Big Finish has stated recently that all of its DW and spin-off audios, except for "Unbound" range and stageplay adaptations form one continuity.
