The opening quote and some loose plot are from the fairytale "Briar Rose".
The Private Investigator's room number shown is 122. this is the first time the season and episode number have been referenced (Season 1, Episode 22).
Adalind previously said she had an Egyptian Mau cat.. Miss Majique is not an Egyptian Mau, though, which Juliette should know being a vet.
The Egyptian Mau is a sleek cat with evenly distributed ocelot type spots. Adelaid's cat looks like a Chocolate Tortie Ragdoll.
Akira Kimura's motel room number, 113, is a reference to the episode number for "Three Coins in a Fuchsbau", the episode in which the Coins of Zakynthos first appeared.
