Despite being credited in the opening sequence, Aisha Tyler, the actress who portrays Lewis, don't appear in the episode.
This is, in fact, the tenth 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 Tyler did not appear as Lewis. The eighth was Profiling 202 and Seek and Destroy, in which Gubler did not appear as Reid either. In the latter episode, Tyler also did not appear as Lewis.
