In flashback, the Knave hunts Alice per Cora’s directive and he finds himself striking a deal to get his heart back, while in present day Wonderland, Alice and the Knave’s friendship is tested as he does Jafar’s bidding and steals from her. Meanwhile, the Jabberwocky attempts to free herself from Jafar’s control and Jafar is confronted by his former partner.
- Building material from Regina's heart vault on Once Upon a Time was re-used to build the entrance to the Wonderland vault. The door, the bricks, the steps, the columns and the beam across the columns are exactly the same as Regina's vault.
- Dan Payne, who plays the Captain of the Guard, also played Ivo in the Once Upon a Time episode "Chosen".
Fairytales and Folklore
- This episode is a rendition of the Alice's Adventures in Wonderland story, focusing on Alice's adventures in Wonderland.
- Also featured is the Knave of Hearts from the same story.
- This episode also features the Red Queen and the Jabberwocky from the story's sequel Through the Looking-Glass, as well as the genie, the magician and the sultan from the "Aladdin" story.
- Jafar's genie wisdom book contains an illustration by the sixteenth century Italian naturalist Ulisse Aldrovandi, from his book History of Monsters (Monstrorum historia cum Paralipomenis historiae omnium animalium), published posthumously in 1642. The illustration, known as "Monstrum tetrachiron alatum capite humano aurito", shows a monster with four arms, wings and large ears.
- The table on the opposite page contains symbols from a page in Key of Solomon, an old grimoire incorrectly attributed to King Solomon. This particular page is from one of the earliest manuscript of the grimoire, entitled The Clavicle of Solomon, revealed by Ptolomy the Grecian, dated 1572. (The three symbols used in Jafar's book can be seen in the lower right hand corner of the grimoire page.)
- Below the table, there are characters from the reconstruction of the mysterious Emerald Tablet, one of the pillars of Western alchemy, and said to be inscribed with the secrets of the universe. One interpretation suggests that the inscription describes seven stages of alchemical transformation—calcination, dissolution, separation, conjunction, fermentation, distillation and coagulation. Curiously, many of the character's in Jafar's book are mirror-inverted.
- Below these characters there is a Latin excerpt from Ars grammatica by Aelius Donatus, a fourth century Roman grammarian and teacher of rhetoric. It says: "Vt docte; conparativi, ut doctius; superlativi, ut doctissime. Magis doctius et tam doctissime non dicimus, quia magis et tam positivo gradui tantum iungitur, licet veteres dixerint tam magis et quam magis. Figurae adverbiorum quot sunt?"
