Trivia: The ships that Riker arrives with are all identical, explained away with the line "I've got a fleet of them at my back." That line's delivered without seeing Riker's face, because it was recorded afterwards. The effects work was only completed shortly before the episode was released, and they didn't have time to create a variety of ships, leading to this "shortcut."
Trivia: The planet that the Riker family settles on is called Nepenthe. A magical potion mentioned in Edgar Allen Poe's "The Raven," originally from "The Odyssey," with the power to cure grief and sorrow. A fitting name for a place to try to forget the loss of a child.
