Twilight, Sunset Shimmer, and Azalea were all trying to break free of the vines that Gloriosa had ensnared them in before she trapped them in the cave. Spike wasn't tied up earlier, so he started to bite away at the plants in order to free them. After chewing away the vines for a while, the dog managed to free Sunset and Twilight. "Nice work, Spike," Sunset said as she pet the dog's head. "Now get Azalea's bindings."
"I can handle my own," Azalea told them as she managed to reach her Multi-Action Dust Baton and make sure it was on the right setting. "It's gonna get a little warm in here, girls," she warned as her body began to shine. With a short yell, a fiery explosion seemed to come from Azalea's body and burn away the vines holding her in place. "Thank you, combination of Dust and Semblance."
"Okay, that was cool. But now we need to get out of here," Sunset admitted before turning back to the boulders blocking the exit. Pushing away at the rocks, Sunset couldn't make them budge. Azalea tried to help out, but they still failed to move them. "She must have tied them up with more vines," Sunset said to Azalea before turning her attention to Twilight. "Twilight, you have to use your magic!"
"I don't think I can lift something that big," Twilight said nervously as she held Spike in her arms.
"It's our only chance of getting out of here and helping our friends," Sunset stated in order to get Twilight to at least forget her worries about her magic. After looking at Spike and Azalea, Twilight had a determined look on her face as she put Spike on the ground and stood before the boulders. Harnessing her magic, Twilight strained as she pushed the boulders and magic gathered at her forehead. In order to ease Twilight's burden, Azalea continued to push the rocks and the cave entrance was soon unblocked.
Twilight felt exhausted from using her magic because she hadn't embraced it like the other Rainbooms, but she still stood up and joined the others as they headed off for camp. Just as they left the cave, they heard gunshots and whimpering from canines. "What's that," Twilight asked before a Beowolf was thrown in Azalea's direction. As the Huntress punched at the Creature of Grimm, it died as her fist made contact with its face. Looking at where the monster came from, the girls and Spike saw Ventus Gaia using his greaves to shoot at one final Beowolf. "Mister Gaia? What's going on," Twilight asked.
"Turns out that Gloriosa has a severe case of the crazies and turned into this plant-witch-spirit-thing," the Falcon Faunus stated. "She's turning the camp into a sea of brambles, trapping everyone inside because that businessman from before wants to buy the camp."
"We need to get to camp, now," Azalea exclaimed as she and the girls bolted toward their destination.
The battle at the campgrounds was still going on as Fragment Hunter continued to kill Grimm and the Rainbooms helped rescue students, but Gloriosa was enraged at the teenagers and Terracotta. "Why are you fighting me?! I'm doing this to save our camp! I'm doing this for you," she exclaimed and sounded like she was losing her mind.
"We literally joined at the last minute," Rua shouted as she stabbed a Scykiri in the face with her weapon. "We crashed this camping trip to have fun with our friends and now you're acting nuttier than a squirrel in a jar of peanut butter!"
Rarity chuckled nervously before she attempted to reason with Gloriosa. "Gloriosa, let's just think about this for a moment, shall we? I mean, I think Camp Everfree is absolutely delightful, but I just don't know that I'm quite ready to give up my weekly trips to the spa."
Hearing what Rarity said, Gloriosa snapped. "To the spa? To the spa!?" Practically screaming the last words, Gloriosa's magic went haywire and thick vines wrapped around her body. Rainbow Dash tried to speed away in order to try something out, but Gloriosa used her vines to trip the girl so she crashed into the other Rainbooms. The members of Fragment Hunter all attacked Gloriosa directly, but she used thorned vines as a giant whip to strike away at the group and knock several of the warriors out cold or break their Aura to leave them vulnerable to damage.
"Gloriosa, this isn't the way," Timber exclaimed to try and get through to his sister.
"I appreciate your concern, Timber, but I got this," Gloriosa exclaimed as her magic continued to go wild, causing her to become a humanoid plant and her vines started to become more like roots that ended up overwhelming and trapping Timber.
"No, you don't," Timber said as he struggled to free himself.
At the same time, the members of Fragment Hunter were getting to safety as they watched Gloriosa going out of control. Looking at who was still able to battle, things weren't looking good for the warriors of Remnant. The only ones left out of the teenagers who could fight were Sunset Blaze, Vinyl Aurum, Slate Quartz and his sister, Silver Wuruhi, and Rua Amaranth. Terracotta stood in front of everyone with Dante by his side as he spoke. "This is getting out of hand. We can't escape, there are still Grimm, and Gloriosa has gone mad with power. If this keeps up, we're going to have to raze Camp Everfree to the ground," Terracotta darkly stated.
"How do you raise something to the ground," Pinkie Pie questioned.
"Raze. R, A, Z, E," Ivy stated as she started healing an unconscious Layla Carbuncle. "It means that we'll have to destroy the camp completely as a last resort."
"Let's hope it doesn't have to come to that," Applejack remarked as Gloriosa's body sparked with green magical energy.
Just outside of the bramble wall, Ventus, Spike, and the girls managed to reach the campgrounds. "Oh great, it got bigger," Ventus exclaimed as he saw the brambles start to form a roof and turn into a dome of vines.
"I think she's finally lost it," Azalea said as she and Sunset tried to pull at the vines. "No good, they won't budge."
"Twilight, do you think you can use your magic again," Sunset Shimmer asked as she turned to the girl in question.
"I don't want to use too much. Midnight Sparkle could take over," Twilight said, not wanting to succumb to magic like the first time she used it.
"Twilight, our friends are in there," Sunset and Azalea reminded as the former grabbed Twilight's hands, ponying up as she did.
Struggling to find the courage to use her magic, Twilight remembered all the moments with her friends ever since she transferred to CHS. Determined to help again, Twilight used her magic to pull away at the vines in order to make an opening for everyone to enter through. When they entered the vine dome, they saw that Gloriosa had been taken over by her own magic and started to become a tree that spread vines and roots all over the camp while Fragment Hunter had to fight off Grimm that emerged from portals inside the bramble walls. "Please, Gloriosa! What you're doing is crazy! You have to listen to me," Timber exclaimed as he was still trapped by the plants created by Gloriosa.
"That isn't Gloriosa," Sunset said as she and the others entered the camp. As soon as she was through, Twilight stopped using her magic and tried to calm herself down as she was still afraid of becoming Midnight Sparkle again. The Rainbooms and Fragment Hunter were happy to see the girls after everything that had been happening. Approaching Timber, Sunset explained Gloriosa's mental state to him. "That isn't your sister. It's someone who's been consumed by Equestrian magic."
"Whoever you are, you have to let my sister go! Please, Gloriosa, come back! I need you," Timber tearfully called out, but Gloriosa was too far gone and vines covered her body completely. "Gloriosa!" With one last call of his sister's name, Timber ended up becoming trapped in a prison of vines.
Soon, the bramble dome was fully formed and a pulse of magic shot through the area, making the vines grow even more and go berserk. Trying to guide Twilight to safety after pulling her away from Timber's vine prison, the girls were soon surrounded by monstrous vines and Creatures of Grimm. Before they could be attacked, Dante used his Semblance to create a large barrier that pushed away the threats while Fragment Hunter and the Rainbooms gathered together. "Rarity," Applejack exclaimed and the fashionista created a barrier of her own to layer on top of Dante's.
With the twin bubble shields holding back the vines, Rarity turned to the others. "I can't keep this up forever," she stated.
"Neither can Dante," Fluttershy said as she heard the Wolfhound-Great Dane mix growling with effort against the vines as he defended everyone.
Seeing everything and taking it in, Sunset Shimmer grabbed Twilight's shoulders. "It's up to you. You can use your magic to pull the brambles apart! Just like how you got us inside," she told Twilight.
"No. There's too many of them. It would take too much magic. I can't," Twilight said, having no confidence in herself.
"Layla's out cold, so she can't help you," Sunset Blaze stated.
"It's the only way," Sunset Shimmer said. "You have to embrace the magic inside you!"
"What if she takes over? What if instead of saving everyone, I turn into Midnight Sparkle and only make things worse," Twilight fearfully questioned.
"That won't happen! We won't let it," Sunset Shimmer and Azalea reassured Twilight. As tears fell down Twilight's cheeks, she began to feel more sure of herself thanks to her friends and began to intensely focus her magic. As her hands and forehead started to glow, the shields began to crack as the vines added more pressure. Rarity and Dante began to weaken from the strain of holding the plants back, making Applejack and Fluttershy keep them steady. "Come on, Twilight! You have to be stronger than she is," the girls told Twilight as Sunset Shimmer and Sunset Blaze grabbed her shoulders. Twilight's teary eyes began to glow as a magic horn grew from her forehead, making her resemble her transformed evil side, Midnight Sparkle.
Twilight was floating around her own personal mindscape, which took the form of a pink starry sky, when she saw Midnight Sparkle behind herself. "You will never control me! I will always be a part of you," Midnight laughed as she taunted Twilight and attempted to merge with her.
Twilight whimpered in fear as she thought that she would become evil and crazy again, possibly hurting her friends. "Noooo!" But before Midnight could even get near Twilight, a stream of flames erupted from out of Twilight's view and burned away at Midnight Sparkle.
As the embodiment of Twilight's fears growled and healed from the burns, she looked around to see where the fire came from. "Who did that!?"
"That would be me," Sunset Blaze's voice sounded off around the area before the real one teleported behind Midnight Sparkle and kicked her in the back. As she did, her foot unleashed a barrage of energy blasts and gemstones that combined to hit the winged monster with several explosions. "And I can do so much more than burn you," Blaze stated as she appeared next to Twilight Sparkle.
"What are you doing here," Twilight asked as she was confused by everything happening in her head.
"My Semblance allows me to connect to a person's mind and Aura for a variety of abilities," Sunset Blaze explained. "I can explore somebody's mental world and even their dreams. In fact, I saw that you were having a nightmare after that campfire and went to help out. But you woke up before I could do anything." Twilight was surprised while Midnight just glared at the intruder. "Now that I'm here, I might as well... provide some therapy," Blaze stated as she looked at Midnight Sparkle.
