Star Trek Picard: Every Easter Egg & Hidden Reference From 'The Impossible Box'

Hugh leads Picard and Soji through the Artifact to safety in the Borg Queen's cell, which the Romulans apparently don't know about. It's not addressed in dialogue, but the La Sirena must not be able to just beam them out of there, which makes sense. A previous trip to the Borg Queen's cell in the Star Trek: Voyager episode "Dark Frontier" demonstrated the Borg had the ability to shield it from transporters through the use of a dispersal field.

Hugh tells Picard this is a newer model of Borg cube from after his time, which is consistent with its slightly updated aesthetics (and not just a production design decision).

The cube also possesses a spacial trajector, technology assimilated from the Sikarians who were encountered by the USS Voyager in the Delta Quadrant. This is a callback to the first season Star Trek: Voyager episode "Prime Factors" in which Captain Janeway unsuccessfully attempts to acquire spacial trajector technology from the pleasure loving Sikarians.

Apparently, in the years since Voyager's departure from that hedonistic planet, the Borg came along and assimilated them and their technology, reserving it for the Queen in the event of an emergency.

As stated in "Prime Factors" and by Soji in this episode, the trajector has a theoretical range of 40,000 light years, which would've been real helpful to the Voyager crew if their leader (whose name kind of sounds like a part of the female anatomy) wasn't so busy perving on Janeway.

Anyway, Picard plugs in the coordinates for a planet called Nepenthe and he and and Soji head to the next exciting episode of Star Trek: Picard.
