- Aja also begins to believe that her parents are not as honorable as she first thought. Her questioning their past actions first began when she learned in "Collision Course" that they have also refused to allow Varvatos and the Phalanx to avenge his late family (as well as hundreds of late Akiridion citizens) by pursuing the Zeron Brotherhood, which led to his ultimate betrayal.

- The "Jim Lake Disease" is mentioned again since Part Two of Trollhunters.
- Steve refers to Coach Lawrence as his [step]father again.
- Steve received Aja's kiss in this episode for the first time in Aja's Akiridion form, albeit briefly and on the cheek.
- Continuity: Aja remarks the time when the Zeron Brotherhood tried to kidnap them with a retrieval ray during their driver's ed. class in "Collision Course".
- Title: The title refers to the term which means to gain benefits and obtaining them through an evil manner or by dishonest means, something which describes Kubritz's intentions of taking alien weaponry for herself.
