The carousel Riley and Dawn are at, is the Griffith Park Merry-Go-Round, in Los Angeles. "All 68 horses have up-and-down action, and they've been leaping in circles in the city park since 1937". The Griffith Park Merry-Go-Round was also featured once on Castle (2009). The location was also used in the movie Buffy The Vampire Slayer (1992).
Anya mentions the demon Sobek, and Glory later prays to it. Sobek was the ancient Egyptian God of the Nile, depicted with the head of a crocodile.
This episode cements Tara's usefulness to the Scooby Gang. After a while with no real contribution to any of theorems and plans, she even describes herself (along with Dawn) as a "non-Scooby" in Real Me (2000), she makes a breakthrough by suggesting that research is useless because the "demon" predates the written word.
Anya's fear of bunnies is referred again when Xander mentions that he would like to come across a cult that worships bunnies.
Buffy refers to the Spawn of Sobek as "big but not Mayor Big," referring to Richard Wilkins becoming the Olvikan in S3's Graduation Day: Part 2 (1999).
