Lunella is heartbroken as she watches everything she cared for go up in flames.
The first half of the season one finale is shining a spotlight on a forgotten yet important character — the original Moon Girl. Who was the mysterious inventor who created the portal generator that brought Devil Dinosaur into the 21st century?
A flashback shows her destroying the original portal generator and being chased by armored men in yellow battle suits. In the present day, guards decked in the same yellow suits are attacking Lunella, the current Moon Girl. After defeating the agents, S.H.I.E.L.D. and Agent Maria Hill arrive with the same question Moon Girl has: who are these bee-themed mercenaries? As S.H.I.E.L.D take the goons away, Maria gives Moon Girl her phone number in case she needs any help.
Back at the lab, Lunella, Devil, and Casey discover there’s a connection between this strange organization and the original Moon Girl. Terrified, Lunella wonders if this group is responsible for the original Moon Girl being erased from history, and if she’ll suffer a similar fate. She shares the news with Agent Hill, but the captured agents escape S.H.I.E.L.D’s headquarters before they can be interrogated.
Later, Lunella is chilling at her family’s skating rink Roll With It, when a male customer flashes a honeycomb tattoo on his wrist that matches The Organization’s logo. It’s a subtle warning that makes it clear this man knows Lunella’s secret identity, where to find her and her family. Lunella escapes to the lab, where she finds someone messing with the portal device while Devil sleeps. The intruder just happens to be…her grandmother Mimi, who figured out that Lunella got her hands on the schematics for the original portal generator.
Not only does Mimi know that Lunella is a superhero, she reveals that she’s the original Moon Girl who invented the portal generator alongside her partner Maris Morlak (the guy with the honeycomb tattoo). The duo used to work for the Enclave, where they developed the portal generator as a means of traveling to space. One day, the Enclave’s head researcher tried to steal credit for inventing the generator so he could sell it to the military. When an enraged Maris activated the device during a demonstration, tentacles popped out and dragged everyone through the portal, with Maris and Mimi being the sole survivors. Maris lost his mind and took over the Enclave, while Mimi escaped.
Before Mimi can destroy the portal generator, one of the Enclave’s agents breaks into Lunella’s bedroom. Mimi rushes upstairs and beats the crap out of the armored goons — while the Lafayette family is oblivious to everything that’s happening around them. Meanwhile, Morlak and his agents enter Lunella’s lab, where they battle Lunella and Devil over the generator. Unfortunately, Devil is seriously injured while Mimi finds her outnumbered. Lunella orders Devil to destroy the generator as Mimi surrenders. Surprisingly, Morlak is unfazed by the generator’s destruction as he captures Lunella and plants a bomb in her lab — with an injured Devil still inside.
As Lunella tries to escape the truck they’re being driven in, Mimi says their handcuffs are activated by their body heat. Lunella is able to break into the truck’s cooling system and uses it’s nitrogen supply to unlock the cuffs. She bursts the truck’s doors open, however, Mimi decides to stay and face the consequences of her past. Lunella is devastated until she remembers Devil. She skates towards the lab at top speed, but the bomb goes off before she can make it. The episode ends with a heartbroken Lunella falling to her knees as she watches her lab go up in flames.
Mimi heads upstairs when an Enclave agent breaks in and Lunella is confronted by Morlak and more agents and she and Devil fight them while Mimi protects the rest of the Lafayettes who remain blissfully unaware. Devil is severely beaten and is ordered by Lunella to destroy the generator before collapsing, while Mimi is overpowered. Morlak captures both Lunella and Mimi before planting a bomb in the lab. As they are being driven away in a truck, Lunella breaks free, but Mimi chooses to stay to face the consequences. Lunella skates back to the lab to rescue Devil, but before she makes it, the bomb goes off, leaving Lunella devastated.
