- "London, 1895. How do I say this? There's a vampire. Half dozen men, snatched off the streets, only to have their bodies dumped three days later completely drained of blood."
- "Vampires, I've waited my whole life to kill one."
- —Nate Heywood and Mick Rory
When Nate thinks he has found a pattern to the anachronisms, it leads the Legends to London in 1895 to hunt down a time-traveling vampire. When they arrive in London, they run into Rip, but not everyone welcomes him back so quickly, leaving Sara to make a tough choice in the end. Amaya tries to connect with Zari, but she is still struggling with being part of the team. Meanwhile, Stein discovers what Ray and Jax are up to and is not entirely pleased.
- The title is a reference to the song of the same name by R&B singer Mark Morrison.
- Rip frequently acts like Arthur Conan Doyle's character Sherlock Holmes, such as deducing a number of things based on a cadaver's appearance, as well as using one of his catchphrases, "the game's afoot".
- In the morgue, Jax pretends to have an English accent. In reality, actor Franz Drameh is actually British.
- Mick Rory is reading Bram Stoker's Dracula throughout the episode. His actor, Dominic Purcell, portrayed Dracula in the 2004 film Blade: Trinity, based on characters from Marvel Comics.
- Mick ties garlic around his neck, Sara quipping that he's a "regular Van Helsing", Nate explaining him to be a character from Dracula.
- When searching for the supposed vampire, Nate hopes for a "Kristen Stewart-type, all broody and sparkly", referring to Edward Cullen and elements from the Twilight saga.
- Sir Henry Stein quotes a line from Act 2, Scene 2 of William Shakespeare's Macbeth.
- There were two total lunar eclipses in 1895: May 18 and November 11. However, only the November one was visible from London, England, almost coinciding with the episode's airdate of November 7. 
- Nate suggests they prop Darhk "up in a convertible like Weekend at Bernie's", referencing the 1989 film.
- When Damien Dahrk "rises" from the coffin the was holding him, the style (body straight and stiff from flat to 90 degrees) is exactly how the vampire Nosferaru from F. W. Murnau's 1922 silent film classic "Nosferatu", rises out of his coffin.
- When travelling in the Waverider, Ray suggests they hold hands, to which Nate says that it's "not Toy Story 3", referencing the 2010 film, in which one of the scenes sees all of the toys holding hands as they are about to be incinerated.
- Zari plays Mortal Kombat II as Liu Kang, fighting against Raiden.
