Inside of Twilight's pink and starry mindscape, Sunset Blaze stared down the representation of the girl's fears, Midnight Sparkle. Using her Semblance, Blaze was able to enter Twilight's mind in order to help her handle her fears. As Midnight and Sunset stared each other down, the latter suddenly produced multiple transparent arms from her back while she held her sword in her original hands. "You're not going to haunt Twilight anymore, you figment," Sunset Blaze declared as she focused her gaze on the monstrous version of Twilight.
"What makes you think that you can stop me? I'll always be a part of Twilight," Midnight replied as she fired a magical blast at Blaze. Blocking the attack with some of the arms forming out of her back, Blaze countered by punching and slashing away at Midnight Sparkle. After taking some damage and healing from it, Midnight channeled more magic and unleashed a barrage of beams that locked onto Sunset Blaze.
Dodging the attacks and even deflecting some back at Midnight, Sunset prepared her next move as she crouched into a runner's starting position. "We'll see about that," Blaze said as she sped toward Midnight. Faster than Twilight or Midnight could track, Sunset decked Midnight in the face with a powerful fiery haymaker that seemed to combine the powers of Rainbow Dash's speed and Applejack's strength as well as Sunset's own Fire Dust. Recoiling from the pain of the attack and regaining her balance, Midnight glared angrily at the Huntress. Summoning a multitude of swords made of magic, Midnight sent the weapons flying at Sunset Blaze like buzzsaws. Defending herself with the arms she created, Sunset struggled as Twilight watched on in fear. The magic blades began to grind against the arms and break through as Sunset thought of something else. "Try getting out of this," she exclaimed as she created a cage of light around Midnight just as the shield broke.
Midnight growled as she saw the cage surrounding her, but smirked as she blasted the bottom of the prison with a beam that opened a rift. Flying through the rift, a second one appeared behind Blaze and Midnight punched the Huntress in the back. "Ha! There's no way to stop me," Midnight declared as she created a number of rifts and began to fly through them, confusing Sunset for a moment as the figment of Twilight's imagination dealt strike after strike. While she was taking damage, Sunset calmed down and dodged the next strike just as it came from behind her. When she did, she activated Cereza's Time Mirage Semblance to slow down everything around her, allowing her to inflict more damage on Midnight by unleashing a string of attacks on her. Knocking Midnight away, Sunset turned to Twilight, who was cowering in fear during the whole battle.
"Twilight, Midnight's nothing! She doesn't exist in the real world. This is all just your fears of what happened before," Blaze told Twilight. Soon, Midnight rushed at Blaze and the two started to grapple with each other. "You're the one in control of your mind!"
"She's right, Twilight," Sunset Shimmer's voice called out. Looking at where it came from, Twilight saw that Sunset Shimmer, the other Rainbooms, and members of Fragment Hunter were all in Twilight's mind as colored projections, likely there because of Sunset Shimmer's magic. "You are in charge!"
"You are a light, darling! A force for good," Rarity stated.
"Yeah! You can kick the darkness's butt," Rainbow Dash exclaimed.
"There's no way in hell that you'll go down easy," Rua declared.
"You're stronger than you think you are," Azalea told Twilight. "I used to be the same way! You can fight your fears!"
"We're here for you, Twilight," Slate, Momo, and Pinkie all said.
"And we'll be here, no matter what," Applejack added.
"We believe in you," Fluttershy stated.
"You... are not... Midnight Sparkle," Sunset Blaze and Sunset Shimmer told Twilight, just as Midnight broke free from the grapple with the Huntress and merged with Twilight.
As Midnight attempted to fuse with Twilight, the latter had a confident look in her eyes due to her friends encouraging her. "All of you are right," Twilight declared with determination as she forced Midnight Sparkle out of her body. "I... am... Twilight Sparkle! And the magic I carry inside me is... the Magic of Friendship!" When Midnight was rejected by Twilight, she only looked on in horror as Sunset Blaze and the projections of Fragment Hunter gathered together and attacked Midnight with a giant energy blast, symbolizing Twilight's fear would no longer control her.
Back in the real world, the vines continued to spread and crush the barriers that Rarity and Dante were using to protect everyone. But before they could break, Twilight flew into the air as she ponied up and shattered the shields. Flying toward the tree trunk that Gloriosa was inside, Twilight used her magic to pull back the vines. When Gloriosa was exposed, she tried to fight back as Twilight grabbed the geodes around her neck. "No! Stop!" As soon as the crystals were collected, they separated themselves and flew to each of the Rainbooms. As the crystals floated and spun in their hands, the seven girls were magically given new clothes and hairstyles fitting for warriors. Energized by the geodes, the Rainbooms unleashed a powerful burst of light that ended up crystallizing the bramble dome and destroyed it.
As the domes remains fell down as lights and gem dust, the members of Fragment Hunter dealt with the remaining Grimm that they saw. Momo pulled out her yo-yo and wrapped the string around a Beowolf's neck before pulling hard on it and decapitating the monster while Ivy pulled out a knife on her belt and cut down a Creep before plunging the blade into the monster's eye to kill it. With the campground clear of Grimm and Gloriosa stopped, the CHS campers rejoiced and cheered for their heroes. Timber woke up and saw that Gloriosa was back to normal, but knocked out from losing her magic. As he approached her, everyone heard the same unholy shriek from before and turned to see what made it. Everyone saw that approaching the middle of the campground was a giant, black, skinless horse with a horned imp growing out of its back and bone plating over both bodies. The imp twitched erratically as it scanned the area and saw the scared people. "Is that the Knuckle-vee thing from the campfire story," Rainbow Dash asked as she slowly stepped back in fear of the Creature of Grimm.
"Not exactly," Ivy said as she was guarded by Dante, Diana, and Drei. "This one looks younger and doesn't have any weapons in its back. It's still a dangerous foe, however."
"WE'RE ALL GONNA DIE," Trixie screamed as she pointed at the Grimm.
"Trixie, shut the fuck up," Rua shouted as the members of Fragment Hunter made sure they could fight.
Before any of them could do anything, Terracotta and Ventus stepped forward. "You kids have done enough already," Terra said. "Now let the adults handle this problem. Ready, Ven?"
"Just like back at Menagerie," Ventus said as he reloaded his greaves, held out his knife, and placed his goggles over his eyes. Immediately, the Nuckelavee threw it arm forward and the clawed limb stretched to try and hit Ventus, only to miss when the Falcon Faunus flew to the side and kicked the monster's arm. The Nuckelavee screamed again as it continued to attack with its arms, but Terracotta and Ventus kept dodging and slashing at the Grimm. When Ventus tried to attack the monster from behind, the horse kicked at him and knocked him away. "This thing's pretty tough. I'll go for the imp, bro," Ven called out.
"Got it," Terra agreed as he focused his attention on the horse itself. Slashing at the Grimm's legs while Ventus kicked at the imp's face, the Nuckelavee was becoming angry as Ventus continued to dodge its claws. After many misses and constantly getting hammered, the Grimm changed strategies and rotated its torso at fast speeds to nail both Huntsmen.
Everyone who watched the fight recoiled in disgust and fear at the Nuckelavee's attack. "That's just horrifying," Rarity shouted and looked like she was going to be sick.
As the fight continued, Terracotta blocked the arms that came flying toward him and allowed Ventus to deal a couple of powerful kicks to the imp's face. Adding onto his assault, Ventus delivered a heel drop to the head of the horse and laughed at the damage he was dealing to the Grimm. However, the Nuckelavee reared and managed to pin down Ventus with one of the claws on the front legs of the horse. As Ventus struggled to get himself free, Terracotta bellowed in anger. "Get your claws off my brother," he practically roared before he saw Timber's axe on the ground nearby. Reaching for it, Terracotta threw the axe into the horse's leg hard enough have it back away.
"Thanks, bro," Ventus said as he returned to Terra's side. When the Nuckelavee balanced itself, the imp's spines and horns grew larger, as if to show it meant business now. Opening its mouth as wide as it could, the Grimm shrieked so loud that everyone had to cover their ears before Terracotta and Ventus could make their next move. "You thinking what I'm thinking," Ventus asked his older brother.
"Oh, yeah," Terracotta remarked as he looked at his sword, Sarangay. Throwing the claymore into the air, Ventus dashed after it with his Semblance. The Grimm threw its hand forward to try and attack Ventus, but the Huntsman was too quick and he grabbed Terracotta's sword. Before the Nuckelavee could do anything else, Terra kicked the horse's head with his own heel drop and damaged the monster's mask-like face. As the Grimm recoiled in pain, Ventus passed by and severed the imp from the horse with one clean slash from the claymore. As the imp fell to the ground, Ventus stomped on the Grimm's head and shot it with his greaves. "One half down, one to go," Terracotta said as he obtained his sword and watched the horse begin to buck wildly. Waiting for the Grimm to charge toward him, Terracotta held onto his sword and let out a loud bellow as he swung his blade. The slash managed to carve the horse's head in two, but the rest of the Grimm's body was bisected by a blade of air that came from Terra's swing.
With the Nuckelavee down for the count, everyone was staring in awe of the fight the just witnessed. When the fight was over, a light from the magic purge fell onto Gloriosa's face and she began to wake up. "What... What happened," Gloriosa asked as she stirred.
"It's okay. It's gonna be okay," Timber said as he was relieved his sister was unharmed after everything. As he hugged Gloriosa, Timber looked at Twilight, who was happy that the siblings were reunited.
Soon, Spike jumped into Twilight's arms and was happy that everyone was fine. "You did it," Spike exclaimed as he was still glad about the threat being over. Soon, he noticed something around Twilight's neck. "Whoa. Nice bling."
Each of the Rainbooms looked to see that the geode crystals they retrieved from Gloriosa had changed to actual necklaces that were now around their necks. "What... What are these," Applejack asked as she held her necklace in her fingers.
"I'm not sure. But clearly we have some kind of connection to them," Sunset Shimmer remarked as Lapis looked at each of them.
"They might be the sources of your new magic. I mean, why else are you all in these new outfits as well," Lapis stated.
"I almost don't care what they are. They are gorgeous," Rarity said as she admired the new accessory. She soon gasped as inspiration struck. "And will totally go with the other collection I was working on for the camp fashion show!" Everyone stared at Rarity as she was still insisting on the fashion show after everything that had been happening during the day. "That's probably cancelled, isn't it?"
"You think," Rua rhetorically asked as she crossed her arms.
