Orwell is named after George Orwell, who is most famous for his novel Nineteen Eighty-Four. Her slogan, "Orwell is Watching," is a reference to the Arc Words "Big Brother is Watching You." Ironically, her secretly fighting against the evil authority is actually more reminiscent of the protagonist's love interest from that novel.
Gregor Molotov spent twenty years in prison obsessing over the cape, which Max denied him because of the darkness in his heart. While this sort of situation is common with his character type, the exact circumstances are eerily similar to Tai Lung's motivations in Kung Fu Panda.
In "Tarot", Orwell uses a fake name: Diane Simone.
