After receiving their medals and partying, everyone went back to their respective homes. Twilight was getting ready for bed by brushing her teeth with a pink toothbrush alongside Spike. Spike, however, saw the disappointed look on his big sister's face as she looked at her medal that she unexpectedly earned after being freed from Cosmos. All thanks to him and Discord.
"Twalight, awe you okah?" he said with his purple toothbrush in his mouth. His answer was a quick look of disappointment and then a sigh as she looks back at her medal.
"Ptoo!" He said as he spit out his white-colored toothpaste. "This.. doesn't have anything to do with Cosmos and that medal that Celestia gave you, right?" Spike said with worry.
Twilight gave him a look, then she scrunched up her eyes, and started sniffling once as she started to bawl uncontrollably as jets of water spouted out of her eyes as she tilts her heads backwards. Spike placed his toothbrush (which was in his right paw to begin with) down on the sink and went over 2 inches over to his sister and placed his paws on Twilight's hips as well as her left arm. Twilight placed her head on his left shoulder as well as placed her right forehoof on his back.
"I.. I.. I did so many terrible things under that monster's control despite the fact that I didn't even know!" She said as she continued to cry.
"What do you mean, Twilight?" Spike said as he pointed his head to the right and pointed his eyes toward his sister's face.
"I was in Cosmos mind while she kept me locked up inside my mind! MY OWN MIND!" Twilight choked as she lifted her head off his shoulders and looked at him face to face. Then, she looked at her medal and picked it up. Then, she looked at in anger with an angry smirk. Finally, she twisted her head to the left and threw the medal away from her and Spike. "I yelled at you, and my friends! And I even hurt Applejack, and locked her up within the Canterlot Archives and did the same exact thing to the Cutie Mark Crusaders and Capper! They were part of the worst moments of my life! Not to mention that I also put the same gemstones on Celestia, Luna, Zecora, and Big Mac! And then, the main problem was, that I always give into my curiosity to learn ancient magic! So how am I supposed to be the Princess of Friendship, when I caused so much terror from cities, to my own friends, *sniff* (voice cracks) and to my own little brother!" Twilight shouted as she pushed her head to the ceiling and then went to put her head back on her little brother's shoulder.
Spike kept patting her back with his left paw as she continues to cry until she fall asleep. Which she did after an hour of crying. Spike used his paws and pulled Twilight out of the bathroom while she remained on his shoulder. He made it to her bedroom and went over to her bed. Spike used all his might and pushed on Twilight's chest and threw her onto her back as she landed on her bed. Spike hopped up and pulled her by the shoulders as he walked backwards and gently lowered her head onto her pillow. Then, he got the bed sheets out from under her body and pulled them up on her while he stood on her left. Then, after pulling her blanket up to her chin, Spike took her hooves out from her right to her left and placed them down on Twilight's blanket. Then, he walked over to his big sister, crawled up on her chest and placed his paws on her hooves as he moves his head closer to hers and kissed Twilight straight on her forehead. Then, after carefully getting off her chest, and her bed, and tiptoeing all the way to the doors, Spike opened them, but he couldn't move as something was holding him gently at his arrow-shaped tail. He looked behind and saw a pink aura of magic surrounding it. Then, he looked up and saw that Twilight was awake as she still had her blanket over her entire body. "Spike, could you, by any chance.. *sighs*.. sleep with me tonight? I don't *sniff*want to feel alone as I was in my own mind being - forced to see all the things that I have brought while being possessed by Discord's ex-fiancé. I mean, I do feel scared knowing that nopony would want me to be the princess of friendship knowing all that I've done while inside that monster who took control of my own body. It's so... heartbreaking when I was used as a vessel to hurt so many of my friends and nearly have the world that I was sworn to protect enslaved by a second evil draconequus," She said with worry as she looked over to her right as she finished that sentence.
"Umm," he said and then flew off with Twilight letting go of his tail.
"*Inhales and sighs deeply*" Twilight sighed as her little brother flew off knowing that he wouldn't want to spend some quality time with a monster. But, as she started sniffling and tearing up in her eyes, she the sound of flapping and pulled her upper body up. Then, she saw the dragon carrying his pillow as he flew through Twilight's door. Then, Twilight smiled as he landed on her bed and stood there smiling. She moved her body a little to the left so that Spike could put his pillow beside Twilight's.
"What? Did you think I would leave you alone while you felt like a monster even though you aren't?" Spike said.
"Right! Hehe," Twilight sheepishly chuckled as she started blushing as she looked from Spike to the right and back towards him.
"You totally felt and thought of yourself like a monster, didn't ya?" Spike said as he smiled and raised his right eyebrow up.
"Hehe, yes," she said as her entire face cheeks turned pink.
"Well, you can't be a monster because I already am," Spike said as he pointed his left finger at chest.
"What do you mean by that, Spike?" Twilight said as she raised her left eyebrow up.
Spike walked up closer, and started to evilly smile and placed his claws under Twilight's head. "Because I'm the tickle monster!" Spike shouted and started tickling Twilight which made her cringe.
"Spike! Pfft! Stop! Ahaha! Please! You know how-how ticklish I am, haha!" Twilight laughed as all her worries were being washed away.
While almost getting tired, Spike started to stop tickling his big sister. "*Sighs* Twilight, I know you feel upset about nearly destroying everything you love... but it wasn't you. Cosmos did all that stuff while... using you and the others' bodies. But, hey, I felt the same way when I nearly destroyed Ponyville when I was a super, giant dragon."
"But that was because of your draconian growth spurt of greed, not by evil," she pointed out.
"Greed? Evil? They're both the same thing. But, anyway, you should know that it wasn't your idea to enslave Equestria just to get answers. Cosmos used it to get the other gemstones," he said as placed his left paw onto her shoulder.
"Speaking of "gemstones," what did Cosmos do to me and the rest who were possessed by her when she got all of the gemstones?"
"Oh! You don't wanna know," Spike said as to not wanting to give her painful memories while she was under Cosmos's control.
"But I do wanna know, Spike. I want to know what she looks like as well as find out what she used all of our stolen magic as well as Zecora's wisdom and Big Macintosh's strength for. So please, Spike, what did she do to you?" Twilight said as she puts her right hoof on her little brother's head.
Spike sighed, and started to speak. "She used used her magic (which was fueled by yours and the other princesses) to turn Applejack, Pinkie Pie, and the Cutie Mark Crusaders into lifeless statues while they were part of a carousel. Next, Cosmos turned me into a dog for the third time in my life. Then, she turned Rainbow and Rarity into fish, and lastly turned Fluttershy into a lifeless puppet," the little dragon said as he looked into his sister's eyes and see pools of tears rising from her eyes. Spike gets out of his covers and both his thumb claws to wipe the tears away. "See, I told you wouldn't like it."
"But *sniff* you only told me of what Cosmos did to you and the others, Spike. I asked "what has become of me and the rest," but thanks, anyway. But what did all of us looked like?" Twilight said as elevates a hoof into the air.
"Well, do you know any memory spells?"
Twilight nods her head once.
"Well, go ahead and try, but, you're not going to like it."
Twilight her elevated right hoof onto Spike's forehead and started to cast the spell which caused her eyes to turn white. When she was inside Spike's memory, Twilight could see that she was standing behind Spike and Discord. Then, she looks past in front of them to see her possessed self and sees herself performing a spell, although she realizes that she never had control of her mind and body in the first place. Then, she sees a pink cloud forming around the six ponies, including herself, and saw herself turning pink and white as Cosmos Twilight and the others were standing on two sides of a giant head that resembled Cosmos. Then, she sees what she and her friends become as she sees that she has been absorbed by the chaos magic to turn into a giant monster. She could see that the monster's tail was Celestia's... but with a blue scorpion tail stinger. She also sees her golden regalia and her golden shoes. But it looked like they also expanded as arm guards for Cosmos's and a helm that contained her horn along with the other princesses from smallest to biggest; shortest to longest. She could see all what has happened to her and her friends and even saw what Cosmos did to each of her friends and little brother. After seeing those painful memories and wiping her eyes with her wings, Spike started to ask. "Wow. I really did become a-," she said until Spike stopped her with an "ahem."
"Come to think of it, Twilight, how DID you come across the first gemstone, as well as ended up being possessed by Cosmos?" He said as he placed his left finger on his chin.
Twilight did the same thing with her hoof and prodded her chin for an answer, until, an answer came which caused the pony to perk up. Then, she looks above her little brother's head and at a wall in anger as she started snorting a lot of air out of her nostrils.
"Uh... Twilight?"
"Spike,... I know how I came across it and who gave it to me."
