Bulk and Skull's reaction to temporarily discovering the Power Rangers' identities is identical to their similar reaction when the Space Power Rangers revealed their identities to all of Angel Grove in Power Rangers in Space (1998)'s "Countdown to Destruction: Part 2 (1998)", as both episodes have the same writer and director, as well as a four-year gap between them.
When the rangers return to the command center after losing their memories, Billy says the same exact thing from the first episode when he encounters alpha. They even show him through alphas perspective which is also from the first episode and original ending credits. As well as Kimberly raising her hand and.say "excuse me like .." is also a nod to tge pilot as well.
This is the first time Bulk and Skull stand up and confront a monster instead of running away from it in fear.
