Q-suke had somehow managed to open the doors of Rescue Dash1 or roll down the windows so it could get out and sit on the bonnet by the time Ukaen landed.
For some reason, Tatsuya has trouble explaining what Rescue Souls are to the children, but he has previously had no such problem when talking to the children at the Himawari School.
Although the transformation into Fire1 X usually carries a time limit, that does not seem to be the case here. Tatsuya is shown as Fire1 X long after the battle is over, although removing the helmet may constitute a power down.
Sakaen didn't seem to be affected by his fall into the cold water of the river.
Hikaru: Saeki's finished vehicles really are the best!
Saeki: Thanks, Hikaru! That makes me really happy!
Hikaru: That's why I made a decision. I'm going to ask to see if I can bring Saeki back with me to Europe.
Taiga: Take Saeki with you?
Hikaru: Yes. Saeki should work for the world.
Tatsuya: Sempai! That's not alright! Saeki can't go with you, Sempai!
Hikaru: You're right. You give Saeki a lot of trouble.
Tatsuya: Sempai, you gave him a lot of trouble too!
Hikaru: Now, now, that was my past...
(Hikaru and Tatsuya start fighting)
Saeki: You idiots! I... I don't belong to anyone!
Q-suke: What's with those faces, you two?
Tatsuya: Today's my first day off in a while...
Hikaru: But Captain Taiag ordered him to spend the day with me.
Hikaru: This is a bigger nuisance for me than it is for you. I'm finally back in Japan... why do I have to spend it with you!?
Q-suke: R1 and Fire1. You two are one-one, you should get along more!
Tatsuya & Hikaru: (together) Who are you calling one-one!?
(Q-suke falls over)
Hikaru: (to a group of children) Today, great teacher Tatsuya will teach you all about Rescue Souls!
Children: (together) Please do!
Tatsuya: Eh? Me... teach... about Rescue Souls?
Hikaru: ...An Extreme Fire boom boom boom breaks out then we, to defeat the enemy... Zoom dwaaan and a fiery Rescue Soul is born! Understand!? Understand? Understand?
(all the children have blank looks on their faces)
Q-suke: Oh well. Rescue Souls are strong feelings to protect people from Extreme Disasters or Extreme Fires. Even you guys have it. It's the desire to save your father, mother or friend when they're in trouble. That is a Rescue Soul.
Hikaru: I made a promise to the children. I would protect more than the people. I will also protect this beautiful nature from Extreme Disasters and Extreme Fires.
Tsubasa: (fighting the Kanikaen) It's a million years too soon for you guys to face me!
Hikaru: R1 Max!
Tatsuya: Fire1 X!
Hikaru & Tatsuya: (together) Double 1 Chakusou Complete!
Tatsuya: Fire Dragon and Rescue Force's vehicles combine. It forms Cerberus Dragon. Its Final Rescue is Cerberus Crash! It freezes the Fire Majin, then all the vehicles slam into it!

The existence of Cerberus Dragon clearly shows that the Rescue Vehicles of both Rescue Force and Rescue Fire are combatible with each other, although what other combinations, if any, are possible is unknown. Presumably the new vehicles can combine with Rescue Striker in the same ways as the originals did in Rescue Force.
As with the previous episode, Hikaru's transformation into R1 is not shown, although he presumably did so while taking the injured man for treatment. Whether he used a chakusou booth or just put the suit on is unknown.
As Hikaru admires the new Rescue Vehicles, Rescue Dashes 1, 3, 5 and 6 can seen in the background undergoing repairs/maintenance.
Joukaen's powerful punches sent Ukaen and Sakaen flying out of the Jakaen lair and into the abandoned buildings. Ukaen passed through a water tank during his descent, powering up the water and giving it a purple glow. He named this liquid 'Dangerous Slime'.
Tsubasa apparently paid no regard to the lives of the crabs that were used to create each Kanikaen as he blasted them to pieces.
The new Rescue Vehicles respond to the same Rescue Cards as their regular counterparts when Hikaru swipes them through the Rescue Commander.
Kanikaen previously appeared in Episodes 9 and 37.
Fire Majin: Kanikaen.
Full Japanaese title: Chakusō seyo, Daburu Wan! Yūjō no Shin Resukyū Gattai.
First appearance of Rescue Shovel Red Type, Rescue Drill Black Type, Rescue Turbo Red Type, Rescue Dozer Blue Type, Rescue Crane Green Type and their combination with Fire Dragon, Cerberus Dragon.
The five Rescue Vehicles seen here are recoloured versions of vehicles that appeared in Rescue Force. The original Rescue Drill also appeared in Rescue Fire Episode 7.
Kanikaen is based on the crab.
Cerberus Dragon is named for Cerberus, the three headed guard dog to the Gates of Hades.
