Sabrina Wildman is the young daughter of Naomi Wildman in the future timeline of Endgame, seen at the reunion marking ten years since Voyager's return before Admiral Janeway erases that history.
Sabrina Wildman appears briefly in the Voyager finale Endgame, in the timeline in which the ship needed twenty-three years to get home.
In 2404 the surviving crew gather to mark the tenth anniversary of their return. Naomi Wildman, who was born aboard Voyager and grew up in the Delta Quadrant, attends as an adult and brings her small daughter Sabrina, whom Admiral Janeway greets warmly.
The child is one of several signs that life has moved on for the crew, alongside Harry Kim's captaincy and the Doctor's marriage. Because Admiral Janeway then travels back to 2378 and brings Voyager home sixteen years early, the future in which Sabrina was born is overwritten.
