The castle seen in the flashback from "Broken Spell (1)" is shown again, as it looks now, in serious disrepair. But someone forgot to remove the bales of hay from the carts lying about the battlefield. As such, it seems like it was just left there before Nick showed up, yet there was no sign of anyone around.
Daggeron misses holepunching his card when morphing.
Phineas: I just saved the light...again! I guess we all have things we're good at!
Nick: I should have known it was you, Phineas!
Phineas: Good to see you too!
Leelee: I just want to be your friend. Is that so hard to believe?
Vida: Nick, Toby needs to see you in his office. He seemed really mad; His eye was doing that twitchy thing again.
Chip: He's the hunter, and we're the prey?
Oculous: That's right, and I'm the best.
Daggeron: (to Jenji) Less pussyfooting and more pounce when we train.
Daggeron: I'm ready when you are.
Megahorn: I'll defeat you quickly, before the others know I'm gone, then I will be the top Terror!
Phineas: (to Nick) You are the Light, the key to destroying the underworld. What a burden. I know. But if you surrender, then we are all lost -- Every bird, squirrel, and fly, caterpillar, alligator, flea. Well, no one really cares about the flea. Except maybe another flea.
The opening credits are revised to feature many new shots of the Red Dragon Fire Ranger. The Dark Seal behind the Centaurus Wolf Megazord is also changed to the same star that appears behind the Rangers when they morph into Legend Mode.
The Battlizer device used to create Red Dragon Fire Ranger mode is not named onscreen (it's a card-puncher like Daggeron's Solar Cell Morpher), but the toy line calls it the Fierce Dragon Morpher.
As hinted at in the previous episode, the mystery figure trailing Udonna on her quest to find Leanbow is revealed to be Clare.
Fire Heart (first mentioned in the aptly-titled "Fire Heart", first seen as an egg in "Petrified Xander", first fully revealed in "Scaredy Cat", and aged to adulthood in "Ranger Down") finally becomes this season's Battlizer armor for the first time this episode, by connecting with Nick to create his Red Dragon Fire Ranger mode.
Was intended to make its worldwide debut on Jetix.tv, via streaming video, on August 14 2006, but the file took until August 16th to finally go live.
Debut several hours ahead of Toon Disney on ABC Family on a SPECIAL day and time of Sunday Morning at 11:30am E&P at the end of a Battlizer themed marathon. Toon Disney debut date: Sunday, August 20 at 9:30pm E&P. Not only was this the first episode to debut on ABC Family since "Koragg's Trial", and not only was it the last episode ever to debut on ABC Family before Toon Disney, but it was also the last episode of Mystic Force to see the light of day on ABC Family, since the JETIX block left the channel on August 31, 2006.
