This is only the second time Earth is actually shown throughout the entire series.
Goof: There is a scene were a large Sectarian and Rhade are scuffling in the Vedran Chamber. The bad guy had Rhade by his gun arm, trying to turn the gun around to shoot him. Rhade's bone blades are bent in three directions, clearly showing they are plastic.
Rommie rejoins the crew in this episode after being rebuilt by Doyle.
Nitpick: It's stated that all High Guard ships needed all three aspects of the ship functioning to override the logic of the core AI (the Avatar, the Hologram, and the Core AI). If that's true, then why didn't Andromeda have an avatar before Harper built Rommie? You'd think they'd come standard just in case of emergency. Indeed, most of the other High Guard ships they came across from the old days, such as the Pax Magellanic, Wrath of Achilles and the Balance of Judgment all had avatars.
This episode marks the first time we see the DNA Sniffer setting on the Force Lance.
The flashbacks of Hohne's presumed death come from the second season episode "Ouroboros".
Nitpick: Harper says that for him, it's been three years since Hohne died. However, Harper has been on Seefra for three years, so when added to the three years he's lived since Hohne's death in the old universe, it's been six years subjectively since he saw Hohne fall to his presumed death.
The First Statue seen is the same used in the Voyage of the Unicorn movie.
The song playing in the background on Seefra-5 when Dylan and Doyle come out of the chamber is the same song played in the Blooper Reel in the episode "Pride Before the Fall" in the ending credits.
Nitpicks: In the teaser, when Dylan is shooting at bottles to test Harper's new gun, there are several issues. To begin with, Dylan shoots his first bottle, which breaks, then a large piece shifts and falls a second later, a highly unlikely result of a round hitting a bottle at high velocity. He then shoots all the rest of the bottles in the line-up, then talks to Harper for awhile. Then he turns back and shoots another bottle, though there were none left unbroken previously. Lastly, the final broken bottle breaks exactly the same way as the first bottle did, and since it broke in a highly improbable fashion, it's extremely easy to see that they just reused the same footage for both shots.
At the end of the episode Trance is flipping a coin, getting tails every time. At the end of the episode "A Rose in the Ashes", Dylan talked to Trance on the Obs Deck. He introduced her to the coin-flipping game, and she guessed wrong the first time when he flipped it and she caught it. Trance claimed that finding the right planet was just a lucky guess, but as Dylan left, she was flipping the coin, and guessing right every time.
In "Star-Crossed", Rommie was terrified she might go insane from being alone, as the Balance of Judgment and the Pax Magellanic did. It finally happened to her.
Goof: The term "nano millennia" mentioned by Rommie makes no sense. The prefix "nano" means one billionth. A millennium is 1000 years. A nano millennium is 1/1,000,000,000 of 1000 years. It works out to about 31.5 seconds. One Thousand "nano millennia" is less than a day. While a computer can do a lot in that amount of time, it can't be the first time Rommie was shut down that long.
The song playing in the bar is the same one Harper listened to in "For Whom the Bell Tolls".
