In The Freeze Zone

1. At the tomb, Ryan climbed down the rope and then tried to call the Rangers but couldn't get through; he likely should have tried calling before going in.
2. On this occasion, Ryan pronounced Loki "Lokee" as it would normally be pronounced, although the "Lo-kai" pronunciation was standard for the villain.
3. Despite being tested for the first time in this episode, numerous previous episodes featured brief uses of the Thermo Blasters.
4. When a fireball shot down from a seemingly high elevation, the Rangers were surprised to see Olympius confronting them nearby, although he'd been standing nearby all along.
5. Olympius called Carter the "last surviving Ranger," but the others were still alive (albeit being frozen) inside Freezard, and Ryan was in the desert.
6. Bansheera made no reaction to the accusation that Olympius had tried to destroy Vypra and Loki, while in As Time Runs Out she had wanted their destruction avenged.
7. Joel had his hat upon being released from Freezard's snow world despite not having it inside.
8. Finding Carter frozen, Dana typed 5-5-5 on his Battle Booster (with no "enter"), and he glowed orange, melting off the ice, and then got up; traditionally, this code was used (with the enter key) for the Booster Beams.
9. The Lightspeed Solarzord formed by itself, as the Rail Rescus and Max Solarzord were merely summoned.
