Trini and Billy apparently had a routine they would use in Ranger fights whereby Trini would boost him high into the air for a high kick; when the weakened Blue Ranger failed to accomplish the move after being stung by Grumble Bee, Trini said he'd never missed that kick before; this seems to imply that there were a number of Ranger fights not shown in episodes.
Bulk and Skull went to the last place the Rangers had been seen, by Angel Grove Lake, to make casts of their footprints to test out on everyone until they found a match; unless there were Ranger battles not featured in episodes, Bulk and Skull should have listed a street somewhere between Angel Grove and Tommy's uncle's cabin as the last place the Rangers had been seen.
Adam dreamt that Tommy fought Drill Master and destroyed him by
impaling him from above with his Zeo
Five Power Sword; Mondo's reviewing of
the destruction of his monsters in 435-MLSt would confirm that Drill Master actually was
destroyed in this matter, so Adam apparently
dreamt about a battle which had actually happened but had never been
shown.
One of the monsters' destructions that Mondo reviewed was what appeared to be a giant
white and silver monster with a hammer,
apparently destroyed by the Zeo Ultrazord
blasts; Mondo said the Zeo Rangers (referring to the teens) had defeated all of the monsters whose destructions were shown, but
such a white and silver monster had not
appeared in an episode.
Ashley eagerly hugged T.J. after the anger spell was removed from the four
teens, suggesting that the team had been
together for some time after the power transfer in 519-PTT2.
Numerous changes which hinted at a significant
passage of time since 639-Ghst include an
apparent reprogramming for DECA, a new bridge alarm, new interstellar flight
abilities for NASADA, Astronema's new alliance with Darkonda, Zhane's
apparent absence for some time, Andros's nearly
forgetting about his new Red Battlized
Ranger power, Astronema's never being
shown using the Psycho Rangers' data cards as planned, and (in 642-CTD1) Darkonda's
missing one or two more lives than he'd been shown losing.
Several factors together implied a long period of
time needed to reach the alien
vessel which Terra Venture changed course
to visit: first, a display showed the vessel at 32% along Terra Venture's path to the Eurolean Galaxy; Terra Venture, somewhat nearby, changed
course to intercept and was therefore roughly 15% to 30% along their
path before changing course; given that the vessel was positioned away
from Terra Venture's course at a
perpendicular distance of 24% of the total path length, Terra Venture would have had to travel a
considerable amount of time to reach the vessel: specifically, anywhere
between 53% and 78% of the distance traveled from 702-QsQ2 to 718-ReMi.
When the Rangers were confronted by fourteen monsters, only seven of which had been
featured in previous episodes (and two of which would be in future
episodes), Joel and Gatekeeper would refer to them
collectively as monsters they'd already
destroyed; this was apparently true for at least the pipe monster.
