In a conversation with Lucius Fox, Bruce Wayne cites rock climbing as an excuse for his activities, just like the adult Bruce Wayne does in a conversation with Lucius Fox in Batman Begins (2005).
The green and purple jacket Selina wears is a callback to the original Catwoman costume from her debut in Detective Comics.
The episode is dedicated in memory of digital compositor Lukas Drake, who passed away on July 30, 2017.
The title is a reference to the Blue Oyster Cult song, "Don't Fear the Reaper."
