Companions

The Doctor's TARDIS

 * The TARDIS experiences some "dimensional feedback" when it arrives on the Holodeck of the Enterprise-D.

Star Trek races

 * The Borg are a cybernetic race originating in the Delta Quadrant, known for their ability to assimilate entire species, incorporating the technology and abilities of each, and converting their members into humanoid drones. In Issue 1 we see Borg invading the planet Delta IV and also attacking various Starfleet vessels.
 * Deltans are a sexually mature, but peaceful species. Their overt sexuality requires them to sign oaths of celibacy before serving in Starfleet.

Technology

 * Prisoners of some facilities used by the Atraxi, the Shadow Proclamation and the Visendi Detention Complex are transported in small green crystals, referred to by the Doctor as an "interdimensional prison cell and interstellar delivery service, all at once." The size of the crystals suggests some manner of compression technology not dissimilar from that of the Teselecta or a Slitheen skinsuit. The crystal containing the unnamed alien prisoner apparently fell to Earth, suggesting it was either being transported or that the crystals have the ability to propel themselves through space.
 * Issue 1 ends with the TARDIS materializing inside the USS Enterprise's Holodeck, a room on board the vessel that combines computer graphics and replicator technology to simulate realistic environments. In the Star Trek franchise, Holodecks are primarily used for recreational pursuits and training.
 * The Doctor recognises Lieutenant Commander Data as an android.

Continuity

 * The Doctor wonders aloud if the escaped alien prisoner was heading to an Atraxi prison or a Shadow Proclamation facility. He concludes the alien is most likely heading to "the Visendi Detention Complex."

The Doctor, Amy and Rory

 * Rory's memories of being an Auton soldier, plus references to the companions being married, places this post-DW: The Big Bang

Enterprise crew

 * Stardate 45635.2 places "Assimilation²" between the Star Trek: The Next Generation episodes "The Outcast" and "Cause and Effect".
