Living Witness

"Living Witness" is the 91st episode of the science fiction television series Star Trek: Voyager, the 23rd episode of the fourth season. This episode takes place in 3100s, when an AI program called The Doctor (played by Robert Picardo) is re-activated by aliens. The events from Voyager's time in the Delta Quadrant, in the 2370s, are viewed through the eyes of history as museum spectators observe recreations of the past, nearly 700 years after the initial events. A backup of the Doctor's program is found and reactivated, allowing him to set the record straight. The episode deals with the topic of historical revisionism and is considered by critics as one of Voyager's best episodes. This episode was directed by Tim Russ, who also plays Tuvok on the series
