===Background information===
The module seems to have kept a real-time backup of the EMH, as The Doctor remembered the events of the attack when the module was stolen.
Its existence would seem to contradict , in which Tom Paris and Harry Kim tried and failed to create the Emergency Medical Hologram Replacement Program. However, since no date or stardate was given in "Living Witness", the only things that date when the module was stolen is Seven of Nine and the state of Voyagers distance from home being 60,000 light-years, placing the episode sometime after but before . Given the reference to Voyagers presence in the Vaskan sector in as revealed in also suggests that the module was stolen around the end of Voyager's fourth season.
=== Apocrypha ===
In the String Theory trilogy of novels, it was revealed that there were several backup EMHs, most of them based on different versions of The Doctor according to when the information was "saved." In the second novel in the trilogy, , a Nacene who had infiltrated the crew by altering their memories – creating the illusion that she was Janeway's sister, Phoebe Janeway, who had accompanied Voyager on their original mission to create a portrait of the Badlands and remained with the crew ever since – was forced to shut down The Doctor and activate the first backup version – essentially the "original" EMH activated in – as The Doctor knew that she was not who she seemed (Significantly, 'Phoebe' had initially contemplated simply altering his programmed memories, but her analysis of The Doctor showed some undefined quality within him that made him more than a simple computer program, suggesting that The Doctor's development at this point in his existence had advanced to a point where he had acquired some kind of 'soul'). Despite his lack of practical experience, the new EMH was still able to confirm that the crew's memories had been altered, as well as explain why Harry Kim and Naomi Wildman had not been affected by the alteration, as the two were slightly 'out of phase' with the rest of the crew as a result of them being duplicates created during the events of , before B'Elanna Torres was able to restore the original Doctor.
