Continuity

 * The Reach warships are remnants from fleet tucked away in the ocean, first seen in "Before the Dawn".
 * Aquaman's line about not putting targets on underage heroes echoes what the Flash said in "Fireworks" to explain why the Team had to operate covertly, as opposed to the Justice League's public operations.
 * Beast Boy pulls up a picture of himself, Blue Beetle and Kid Flash from taken after they saved the meta-teens in the previous episode.
 * He also pulls the the selfie that Angel O'Day took with him in "Influence".
 * Beast Boy repeats Superboy's line from "Fireworks" when he stands up to the League, "Get on board or get out of the way". The latter even grunts and rolls his eyes out in recognition.
 * Blue Beetle says the Reach outed him two years ago, referring to "Complications", when under their control, he unmasked himself to the public and acted as an unwilling advocate for the Reach.
 * Geo-Force states that Markovia and the world know he's a Meta-Human, which happened in "Eminent Threat".

Trivia

 * Number 16:
 * The comment posted by the M-HYC 1K Wordsworth account has 16 million re-posts.
 * Celia Windward's account is @CWindward16.
 * Angel O'Day's selfie with Garfield has 160 million likes.
 * Sheriff Maguire quotes "The Good Samaritan Law", from Brooklyn Statute 1660, to let the Outsiders off the hook.
 * End credits shot: Brucely sleeping next to Lian's bed, cuddling a Kid Flash plush.

Goofs

 * The final scene features two reused shots from the meeting in the Batcave in "Triptych":
 * The shot of Batman cross-armed and Robin standing next to him with his left hand on the waist.
 * The close-up of Wonder Woman turning her head to the left. This is actually a reverse shot of the original scene, in which she turns her head to the right, while asking what the Reach device did.

Cultural references

 * The Hub's computer has a notification Beast Boy has named the "Troub-Alert". This was the name of a similar system in the Super Friends animated series.
 * Mayor Tompkins' derisive comment about a "Newsgirl Legion" is a reference to the Newsboy Legion, the young allies of the Golden Age Guardian in Brooklyn, NY.
 * Several references to Scooby Doo and in particular, the animated series Scooby-Doo! Mystery Incorporated, appear in this episode.
 * Antonia loses her glasses, which she is helpless without, much like Velma Dinkley.
 * Sheriff Patrick Maguire resembles Crystal Cove's sheriff Sheriff Bronson Stone. Troy Baker emulates Patrick Warburton's voice for the character.
 * Mayor Tompkins resembles mayor Fred Jones, Sr., who also has a child with the same name and is reluctant to allow the gang to do their exploring and news gathering.
 * The alien monsters turn out to be humans in disguise, and Whisper A'Daire laments that they could've gotten away with it, if it wasn't for those meddling kids; this was a common ending for Scooby-Doo episodes.
