See flashback (psychology) for the psychological phenomenon.

The 30th anniversary episode that spans the generations!"Flashback" was the 45th episode of Star Trek: Voyager, first aired on 1 October 1996. The episode story was written by Brannon Braga, directed by David Livingston and novelized in by Diane Carey for Pocket Books.


When Lieutenant Tuvok begins to suffer from bouts of repressed memory—which can cause brain damage in a Vulcan—the solution is a mind meld between Tuvok and Captain Kathryn Janeway. It's a remedy that takes them back to Tuvok's first assignment aboard the USS Excelsior commanded by Captain Hikaru Sulu. The Klingon moon Praxis has just exploded, and the key memory seems to be the death of a crewmember during a skirmish with the Klingons.
