This little Easter egg might only get picked up by the most hardcore "Dracula" fans in the audience; you have to be familiar with the 1897 Bram Stoker novel (or the 1992 movie adaptation directed by Cage's uncle Francis Ford Coppola, which directly inspired his performance) to connect the character played by Awkwafina to one of the original novel's most important players.
The name of the character played by Awkwafina is Rebecca Quincy. She is a police officer with a true heart and a dark past that gives her reason to unite with Renfield against the Lobo crime family. Ultimately, her friendship helps Renfield see the error of his ways, and together they help each other do good.
Rebecca's last name, Quincy, is most certainly a reference to Stoker's original text. In the "Dracula" novel, there is a character named Quincey Morris. The names aren't the only similarity, as these two characters serve similar narrative functions in their respective tales.
In Bram Stoker's "Dracula" novel, Quincey Morris helps Jonathan Harker defeat the vampire lord. He is a character who went on to appear in multiple adaptations of the tale. This film's Rebecca is a new twist, yet still plays the role in aiding Renfield to overcoming his toxic boss, aka Dracula. By more than just name, Rebecca Quincy is a clear part of the lineage that "Dracula" fans have seen over the years.
