Re: Unworthy - Discuss/Grade Thread <SPOILERS>
Well, if 8472 could infiltrate Starfleets computer network, they could easily create a personnel file for a Commander who's been on extended leave for a few years, or who's just returned from a long assignment on some backwater planet...^It would appear that there never was a Batiste, or not one that any living person in Starfleet would remember. I didn't like that plotline much either, but overall the Voyager relaunch has improved in leaps and bounds since the Golden era (how ironic is that comment?) and I look forward to seeing where it goes from here.
There probably was a Batiste at some point. The earliest the Species 8472 Batiste could have infiltrated Starfleet was 2374 (as that is the year Scorpion ended). By the time of Unworthy in 2381, he could have been in that role at most 8 years, an awfully short time to start from scratch and become Admiral. And I doubt it would be terribly easy to just appear in Starfleet as a Commander or something without anyone noticing. So he probably did replace a 'real' Batiste who had already moved up the ranks on his own.
