Referbacks

 * Accelerator was previously seen modifying his crutch in Episode 15, at the start of the arc's events. Its true new function, to counter attempts to jam and disable Accelerator's choker, is revealed here, having obtained the necessary information to do so when his choker was remotely disabled in the previous episode.
 * While explaining what it is, Aiwass refers to Fuse Kazakiri, revealing that the artificial angel formed from the aggregation of AIM Diffusion Fields was also something of a production line used to give it form and allow it to manifest.

Cultural References

 * The basis of Tecpatl's grimoire is the Moon Rabbit, specifically the version from the story of the creation in Aztec Mythology, where the moon was created at the same time with an equal shine and the gods threw a rabbit at it to weaken its glow.
 * is a key figure in Thelema, being the entity who was said to have contacted in Egypt on April 8th-10th 1904, and dictated the contents of what would become  to him. Recorded in the book is the central tenet of Thelema; "Do what thou wilt shall be the whole of the Law".
 * Though the terms are not mentioned in the episode itself, the preview for this episode refers to the Thelemic concept of Aeons, specifically the Aeon of Osiris and the Aeon of Horus which comes after it.
