The human wife of Voyager's Doctor in the future timeline shown at the start of Endgame, whom he brings to the crew's reunion ten years after their return to Earth.
Lana appears in the Voyager finale Endgame. The episode begins in 2404, in a future where Voyager took twenty-three years to get home and its surviving crew gathers to mark the tenth anniversary of their return.
The Doctor arrives at the party with Lana on his arm and introduces her as his new wife. He also announces that after three decades he has finally chosen a name, Joe, which he says was the name of Lana's grandfather.
Tom Paris teases him about the choice. Lana and the marriage belong to the timeline that Admiral Janeway sets out to change, and they are presumably erased when Voyager reaches Earth in 2378 instead.
