- Virgil Williams, who wrote this episode, also wrote the episode's predecessor, Season Seven episode Profiling 101.
- Despite being credited in the opening sequence, Matthew Gray Gubler, the actor who portrays Reid, doesn't appear in the episode.
- This is, in fact, the eighth episode in which a main character has not appeared despite his or her actor or actress being credited as usual. The first episode was Broken Mirror, in which A.J. Cook and Kirsten Vangsness do not appear as JJ and Garcia, respectively, despite being credited. The second was 25 to Life, in which Thomas Gibson does not appear as Hotch. Three Season Eleven episodes were part of a small story-arc, in which Gubler also did not appear as Reid. The sixth and seventh were Taboo and The Anti-Terrorism Squad, both in which Aisha Tyler did not appear as Lewis.
