John Crichton, along with several of his Moya crewmates, returns to present day Earth.

During this period they are extensively videotaped by Bobby Coleman. At one point, Jack Crichton becomes the first human to visit Saturn, courtesy of Aeryn Sun. 
At some point during their visit, Aeryn Sun is interviewed for the TV program Alien Visitation, but the episode is temporarily suppressed by the US government. Ka D'Argo makes an appearance on Late Show with David Letterman. 
Toward the end of the crew's stay on Earth, Sikozu grows tired and joins Scorpius in guarding the wormhole. 
A Skreeth attacks John, Aeryn, and the Crichton family on Christmas Eve after killing DK and his wife. 
John Crichton and the Moya crew choose to leave Earth.
