2 - 5: Non Sequitur

Stardate: 49011. Ensign Harry Kim arises one morning to find he is back in San Francisco on Earth with his girlfriend, Libby. In this alternate reality, Starfleet records show he never served aboard Voyager, which Starfleet considers lost. Instead, Kim works in Starship Design at Starfleet Headquarters. To help him restore reality, he enlists the help of a shady figure in France named Tom Paris, who has no idea who Harry is.
