Continuity

 * Courtney Whitmore recaps the Outsiders' recent missions in Taos ("Illusion of Control") and Brooklyn ("First Impression"). The third mention, Chicago, happened inbetween episodes.
 * Violet asks Helga Jace if Brion found out Gabrielle Daou (indirectly) killed his parents, a discovery that Violet made in "Leverage" and confided in Helga in "Illusion of Control".
 * Helga Jace confesses to Violet that she tested a strand of her hair in "Illusion of Control".
 * Joan Garrick has passed away. She was shown in a hospital bed, with her husband at her side, in "First Impression".
 * Project Rutabaga was name dropped by Lex Luthor in "Evolution".
 * The letter "K" that Klarion brands onto the meta-teen's forehead was previously seen on a girl held captive in the Orphanage in "Influence".

Trivia

 * Number 16: The Outsiders arrive at the Meta-Human Youth Center at 16:51 MST.
 * End credits shot: An outside shot of the Tower of Fate with Klarion and Teekl inside still trying to escape.
 * Klarion's exclamation "Now, that's a Rutabaga!" hearkens back to "True Colors", in which an off-screen character shouted the same line while touring a LexCorp Farm.

Goofs

 * Courtney Whitmore shows media of an Outsiders mission in Chicago, but the building in the image reads "First Bank of Metropolis".
 * The Military Police Humvee has "Militar Policia" emblazoned on the right front door, but in Spanish adjectives are placed after the nouns they describe, so it should read "Policía Militar".
 * The way Harper is resting her right hand on her hip while holding the gun is physically impossible.

Cultural references

 * Beast Boy's catchphrase "Outsiders, Away!" echoes the battle cry "Titans, Go!" used by Robin in Teen Titans.
 * Static is amused by Beast Boy turning into a green hornet, possibly alluding to the fictional masked crime-fighter of the same name.

Unanswered questions

 * Who is Helga Jace's mentor?
 * Who are the Meta-Humans created by Klarion?
