Right after the Megazord dodges an attack by Goldar, the next shot is of a view of the Megazord control room. However, while four of the five seated Power Rangers have their correct images, the Red Ranger does not. Instead of the red Tyrannosaurus insignia, it shows the green Dragon claw insignia of the Green Ranger. The Green Ranger wasn't introduced yet, which means this was footage taken from a later episode.
Jason recognizes the power crystals and knows how to use them despite never having the opportunity for Zordan to tell him about them.
