 * The scene where the girls find themselves on the moon is a tribute to the 1968 film "2001: A Space Odyssey", featuring the iconic black monolith, Richard Strauss' "Also sprach Zarathustra", and Kuroko briefly wielding a femur as the ape did in the opening of the film.

Unanswered Questions
Where does this episode fit in the timeline of the series? It cannot possibly take place between the day Mikoto battles Harumi and AIM Burst (July 24) and the day Touma loses his memory via Dragon's Breath (July 28), as Touma was unconscious from his battle with Kaori Kanzaki (also July 24) until the afternoon before Index's scheduled memory loss (July 27) and he had spent the remaining time inside Komoe's house calling memory institutions- yet he appears at the end of the episode. Furthermore, it cannot take place after Touma loses his memory because he doesn't recognize Mikoto until the start of the Sisters arc (August 20), and Mitsuko bonds with Kinuho and Wannai starting from here and brags to them in Railgun Episode 24 about her heroics during the climax of the Poltergeist incident (August 9).
