Meanwhile, Jafar’s plan to kill the Knave puts the Red Queen in a difficult position as she grapples with her feelings for him and her desire to get what she wants.

Fairytales and Folklore
- This episode is a rendition of the "Aladdin" story, focusing on the appearance of the sorcerer; and the Alice's Adventures in Wonderland story, focusing on Alice's adventures in Wonderland.
- While running from the Collectors, Will splits up from Alice with the promise to meet her at "Tulgey", a reference to a stanza from the novel Through the Looking-Glass, where the Jabberwock "Came whiffling through the tulgey wood".
- On the Red Queen's orders, Will is sentenced to be executed via beheading and is put on the chopping block, a reference to the way the Queen of Hearts repeatedly calls for the beheading of those who displease her in Alice's Adventures in Wonderland. The crowd shouts "Off with his head", a reference to the Queen of Hearts iconic lines from the novel.
- The Red Queen sits in her throne room, playing chess all by herself, a reference to the novel Through the Looking-Glass, where chess is the most important theme of the story.
- One of the pages in the Genie wisdom book contains an illustration from Heptameron, or Magical Elements (1496), a grimoire by the thirteenth century Italian philosopher Pietro d'Abano. It is "The figure of a Circle for the first hour of the Lords day, in Spring-time".
- Another page contains a table filled with 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 the book can be seen in the lower right hand corner of the grimoire page.)

- The set used for the interior of the Blacksmith's workshop is a redressed version of Farzeen Shahmed's shop from "Trust Me". The same set doubles as the interior of Ulima's house for the episode "Bad Blood". The easiest way to spot this is the doorway, which has the same unique shape in all three locations.
- Burnaby's Central Park doubles as Wonderland for the scene where Alice and Will are running from the Collectors and the scene where the Red Queen captures Will. Parts of the episode was filmed on a closed set in the park, before the production moved to a more public path in the evening for exterior scenes.
- Some scenes were filmed at the North Shore Studios, due to the Neverland sets at The Bridge Studios, the studio used to film Once Upon a Time, taking up too much space.
