In keeping with the title scheme of the second arc, this episode's title spins off another work of literature: Through the Looking-Glass. This is a sequel to Alice in Wonderland, a book that has been connected to Artemis in several ways throughout the series: she has a big poster of an illustration from the story on her bedroom wall, her sister's moniker was taken after a character from the book and her origin story was told in two tie-in comics titled after elements from the book, "Rabbit Holes" and "Wonderland". Artemis is seen reading the book in the first flashback and she quotes a passage from it in the end credits scene. In a more literal sense of sorts, it can refer to Artemis watching her sister interrogating Onyx and Cassandra Savage through a monitor screen.
Cassandra says Lady Shiva sent out Manta Troopers a few weeks ago and that's how they figured out Tigress was leading the Team. This was seen in a still shot in the previous episode.
The music Artemis was listening to in her car in the previous episode is revealed to be from Superboy Fan Memorial.
Cassandra's line to Rictus "Do you really believe you have what it takes to bring down the daughter of Vandal Savage?" echoes her father's line to Kid Flash in "Coldhearted", "Do you really think you have what it takes to survive Vandal Savage?".
Jade's meet-up code "We're all mad here" is a line from Alice in Wonderland, uttered by her namesake character, the Cheshire Cat. While the follow-up line "Mad as Hatters" is not from the novel, it alludes to the Hatter, another character from the novel, popularly known as the Mad Hatter.
Jade's line "And your little dog too" is a reference to The Wizard of Oz when the Wicked Witch of the West threatens Dorothy.
The book Jade gives Artemis in the flashbacks, Soh Dah (Dumb Luck), is a 1936 novel by Vietnamese novelist Vũ Trọng Phụng which satirizes the late-colonial Vietnamese middle classes.
