• Ransom records the stardate as 59482.3 in his log.
• The USS Cerritos is hosting peace talks between two different photonic species, the creatively named Orbs and Cubes. Previous photonic lifeforms encountered include:
• Beings interpreted as the monster Grendel by holodeck characters - “Heroes and Demons”
• A trans-dimensional species that entered the holodeck, and promptly found themselves in a war against the pulp character Chaotica - “Bride of Chaotica”
• Photonic fleas - “The Voyager Conspiracy”
• Among the bits of circular furniture ensign Olly is attempted to stack on a hover sled is a “ball chair” like the one Worf had in his quarters for much of TNG, and a dabo table, as seen in Quark’s in DS9.
• The USS Reseda has not been mentioned previously, but is likely a California-class, based on being named after a neighbourhood in Los Angeles.
• According to Mariner, the crew of the Reseda is entirely reformed Maquis. Most of the Maquis were wiped out by the Cardaissian Union and the Dominion, as per “Blaze of Glory”.
• Olly is descended from the Greek god Zeus. We learned in “Who Mourns for Adonais” the Greek pantheon wer actually alien beings who visited Earth and were sustained by the worship of humans.
• ”Didn’t Kirk kick their asses?” To the best of our knowledge, Kirk only encountered Apollo. The USS Enterprise destroyed his power source, a temple, from orbit.
• ”I thought they all went off and became ‘one with the wind,’ or whatever.” In “Who Mourns for Adonis”, Apollo does claim the other Greek gods, ”returned to the cosmos on the wings of the wind.”
• Admiral Vassery was introduced in “Moist Vessel”.
• Olly has been removed from six ships before arriving to the Cerritos. In “Hollow Pursuits”, Captain Picard said of Reginald Barclay, “It’s easy to transfer a problem to someone else. Too easy.”
• Boilmer’s beard growth remains the most consistent storyline this season.
• In Rutherford and Boimler’s quarters, we see that Boimler has added a doll of Data in the “Star Trek: First Contact” uniform to his Mirror Archer and Spock figures. On Rutherford’s shelf, there’s the model of DS9 he got in “An Embarrassment of Dooplers”, as well as a recreation of Wesley’s portable tractor beam from “The Naked Now”.
• Rutherford is aware that Boimler keeps looking at the PADD he stole from the minor universe in “Dos Cerritos”.
• ”Also it’s red.” We’ve seen red PADDs in “Coming of Age”, “Clues”, “Lower Decks”, “Homefront”, and “Image in the Sand”.
• Tendi is also aware of Boimler’s stolen PADD.
• ”Good joke. We got a real Roland B. Moore over here.” Ronald B. Moore was a visual effects supervisor on TNG, and, according to a display outside the holodeck, was also the name of the stand-up comedian program played by Joe Piscao in “The Outrageous Okona”. Based on the fact that Boimler is claiming Rutherford was being funny, I believe we can assume he was talking about the visual effects supervisor.
• Apparently Olly was assigned Mariner’s old bunk, which we haven’t seen since the Lower Deckers moved out of the hallway bunks in “I Have No Bones Yet I Must Flee”.
• ”You don’t have to be Dixon Hill to see that some bad shit went down in here.” Dixon Hill is the fictional private investigator whose adventures Picard likes to relive on the holodeck, as per “The Big Goodbye”.
• ”If we get some Ferengi blood, we’ll have an entire rainbow!” Ferengi blood is yellow, as first seen in “Mugato, Gumato”.
• ”What about Shaxs? You’re in the bear pack.” Boimler was made a member of the bear pack in “Empathalogical Fallacies”.
• The Sphere Rondus, as well as the gestalt Sphere, Orbiculus, are voiced by Fred Tatasciore, who voices Shaxs.
• ”Didn’t you learn this with the whole Hawaii thing?” Tendi is recounting the events of “wej Duj” when Boimler claimed to be Hawiian to be able to join Ransom’s group of other [fake] Hawaiians.
• The Cube Sexagus, as well as the gestalt Omegacube, are voiced by Carl Tart, who is the voice of Kayson.
• The Sphere Spheronius is voiced by Jerry O’Connell, who is the voice of Ransom
• ”To be fair, Qs are more annoying than scary.” In “Q-Less”, Sisko punches Q in the face and he never returns to Deep Space 9.
• The Cube Quadralon is voiced by Jack Quaid, who voices Boimler.
• The Sphere Radiara is voiced by Gabrielle Ruiz, who voices T’Lyn.
• We learn that Quadralon and Radiara were not murdered, but instead ran off together after a night of passion that trashed Quadralon’s room. No confirmation as to what the square shaped “photonic residue” on the walls of the chamber were. “The Outrageous Okana” also featured a “Romeo and Juliet” romance between two children of conflicting colonies, resulting in a pregnancy.
• SquAaron is voiced by Roan Lai, who was also the voice for the moopsy in “I Have No Bones Yet I Must Flee”.
• ”I love the brig, this is my favourite place.” Olly echoes Mariner’s words to Ransom from “Temporal Edict”. However, she’s a bit more chill so she doesn’t also claim that she’s going to ”dance in [anyone’s] blood.”
Yeah, "Ronald B. Moore" was just seen on the holodeck Okudagram in the original episode. It may not have been legible in the pre-remaster version of the show.
