Some of Nora's lines in the episode are from what Barry said in the first and second seasons.
Many references toward Nora's origin are lifted from the pilot episode, such as:
- Nora running late to a crime scene
- Nora waking up after an accident to "Poker Face" and discovering her powers
- The first time she used her super speed, Nora accidentally ran into a truck, getting confused about what just happened. The same thing happened to Barry in the pilot.
The footage of Zoom that Nora watched at the Flash Museum was taken from "Rupture".
Nora tries to apprehend two robbers Bug and Byte, who in the comics, are a brother and sister duo and enemies of Firestorm. They appeared in The Fury of Firestorm #23 & #24 (1984)
Godspeed had white armor, two headpieces on the side of his helmet with demonic black eyes. He even had a lighting bolt symbol on his armor chest, like the original Godspeed's appearance.
