Dick instructs Violet to stay behind so that she can administer a "Halo-cleanse" to Victor, who is possessed by a Father Box and has gone on a murderous rampage in "Another Freak" and "Nightmare Monkeys". On both occasions, Violet healed him back to normal, albeit temporarily. They are still looking for a permanent solution.
Dick's debrief of Brion features flashbacks with footage from previous episodes:
Forager declares to have a special relationship with the Bio-Ship, which started out in "Away Mission".
Black Lightning is happy to let his powers loose on Devastation. This refers to the trauma he endured after unintentionally killing a kid in "Princes All" and since then he has been afraid of using his powers.
The masks worn by the auctioneers bear a striking resemblance to those used by the Court of Owls.
The map of Greater Bialya is the same map that previously appeared erroneously in "Beneath".
After Helga Jace picks up the brush, her hair is gray.
Mister Bliss' welcome in three languages to the audience is taken from the opening song of Cabaret, "Willkommen". His appearance – a tuxedo and grease paint face – is similar to the way the Kit Kat Club's Emcee is traditionally dressed.
