This episode was produced from April 11 to April 17 of 2019.
The episode title is a take on Charles Dickens' novel "A Tale of Two Cities."
Whether by design or accident, when Piper says "Relax. I speak fluent Robot," she sounds like comedian Reginald D. Hunter saying "Relax. I speak Irish" in his 2011 concert special "Reginald D Hunter Live."
Ray refers to Future Piper as "Loony Gaga" (a parody of the name Lady Gaga).
Neither Henry nor Ray appear as their superhero alter-egos.
