Continuity mistake: Bash takes his shirt off revealing the wound on his right arm. He starts wrapping it again with cloth and the scene cuts to Kenna. It cuts back quickly to Bash and his bandage is fully tied. There is no way he could accomplish this one handed.
Other mistake: If you look closely at the army of Rangers in the opening credits, you can see four versions of Tommy Oliver: Green Ranger, White Ranger, Zeo Ranger Red, Black Dino Ranger. Even though he had a single clone made, he can't be four variations at the same time.
Factual error: The conversation between Taylor and Michelle tells us that school is over for the day and that Taylor talked to her crush at lunch. When the boy shows up at the bakery later, he and Taylor plan to meet at 3 that afternoon; if its before 3, they should still be in school.
Factual error: In the last minutes, the show looks forward to future challenges, in effect a preview of the never-made 3rd series. The oracle says they must find "the golden fleece, woven long ago by the Stygian witches." But the golden fleece, or indeed any fleece, is not a woven fabric. (Today's fleece is a modern invention).
Continuity mistake: Throughout the episode Lieutenant Abbie Mills' lapel mic changes from scene to scene. It goes from the Motorola Commander Speaker Mic to a standard Motorola mic without the orange emergency button, volume control, 16 channel selector knob and 2 programmable buttons.
