Descent
Stardate 46982.1: The Enterprise arrives at the site of a recent attack on a Starfleet outpost, only to find the Borg in orbit in a new class of vessel much larger than their previously known forms of transport. The Borg have also changed, now possessing some form of individuality and emotion – and they have also developed a desire to simply kill organic life forms, not absorb them into the Borg collective consciousness. A squadron of Borg attack an away team from the Enterprise, and Data, in the process of fending off a Borg, experiences an inexplicable flash of ruthless anger and kills the Borg. The attacking party defeated, the away team returns to the Enterprise and Picard contacts Starfleet. The new Borg pose an unknown but likely more serious threat than ever before to the Federation. After determining the new Borg ship’s method of propulsion, the Enterprise follows and is attacked once again. Meanwhile, Data has yet to make any further progress in his analysis of his first emotion – but a captured Borg makes Data a seductive offer to experience more emotions…and it turns out to be an offer Data cannot resist.

LogBook entry by Earl Green
Ford arrives on Lamuella, is promptly brained by Arthur’s daughter Random (who then steals his ship), and finds himself stranded with the sandwich maker. Ford had intended to contain the prototype of the new Hitchhiker’s Guide by sending it to Arthur’s backwater planet, and is dismayed to find that the new Guide is now guiding Random’s actions. Ford reveals that the new Guide operates across all dimensions and all planes of probability, and is using Random – just as it used him – to bring about the final destruction of Earth across every reality at the behest of the Vogons. Random pilots Ford’s ship to Earth, where Random starts looking for her mother but finds only the wrong Tricia MacMillan. When the Guide v2.0 fails to provoke Random’s more violent feelings, it leaves her high and dry. Ford and Arthur, despite being on a backwater planet, find a ship to take them to Earth. But as the new Guide brings its programmed plan to a conclusion, it turns out that Earth is a very, very unhealthy place for Arthur Dent to be.
