The next day was in school. The other students seemed to be treating Sunset like they did when Cherry, Atticus, Mo, and Patch came to Canterlot High for the very first time. Except Flash Sentry treated Sunset as a friend.
"Flash, you still believe in me?" Sunset smiled.
"Well, yeah..." Flash smiled back, seeming to blush from her smile. "I just wish I could help you guys."
Sunset accidentally bumped into a student who was texting on his phone and soon held out money rather fearfully to her when she offered a hand to help him up. "I don't want your lunch money! I'm not mean! Got it?! I'm not mean!" she then glared out of aggression.
"She's telling you the truth." Flash Sentry said.
The boy soon ran away since Sunset was angry.
"Maybe I got a little too angry." Sunset said nervously.
"Just a little." Flash Sentry said.
Mo, Atticus, Patch, and Flash Sentry soon had an idea who would have The Memory Stone as they saw Trixie.
"Suspect #1: Trixie Lulamoon..." Mo commented.
Atticus slammed the girl's locker door shut.
"So, here we are." Sunset glared to Trixie.
"Here we do are..." Trixie replied.
It soon looked like The Good, The Bad, and The Ugly with showdown music in the background.
"So, you really wanna do this now?" Trixie glared.
"Up to you." Atticus glared back.
Patch even growled like the dog he was. Mo looked ready to fight Trixie.
"Behold!" Trixie beamed as she brought out a magic show poster. "Canterlot High School's Greatest and Powerfullest Student! If a seven-scale mock-up doesn't convince you, I don't know what will."
"You think this is what we're here talk to you about?" Flash asked her.
"Well, I can't imagine why else you would be here." Trixie shrugged smugly.
"The Memory Stone!" Sunset glared. "Where is it? You turned our friends against me just because I wouldn't put you in the yearbook as the Greatest and Powerfullest?! 'Powerfullest' isn't even a word!"
"What are you talking about?" Trixie asked.
"Oh, don't act innocent with us," Cherry glared. "You know what we're talking about, you showboat!"
"A stone that could make everyone forget all the bad tricks I've done...?" Trixie asked before looking back, showing she really didn't know. "Which is no tricks. Your puny rock pales in comparison to the Great and Powerful Trixie!"
Patch soon stopped growling as he had a feeling Trixie wasn't the one.
"I don't believe it," Sunset frowned. "You have no idea what we're talking about."
"I,... Don't... Sorry..." Trixie replied apologetically.
Patch simply sighed as that was the only culprit they had. Sunset Shimmer groaned as she sat down by the lockers.
"Did somebody really erase everyone's memories of you?" Trixie asked.
"Well, not every one's," Atticus replied. "We put salt on our window sills."
Trixie looked confused to that.
"It's the only way to block out Equestrian magic from our houses." Atticus said.
"Uh... That's interesting..." Trixie blinked oddly.
"Also, Sunset Shimmer isn't mean anymore, she's changed since the Fall Formal," Mo told Trixie. "At least, that's what the others told me, and they would never lie to me."
"It's complicated." Sunset added with a sigh.
Trixie soon understood what Sunset was going through. "So you have this idea of who you're supposed to be, but no one at school sees you that way," she then said to the former mean girl of Canterlot High School. "Is that it? Trust me. I get it."
The group was surprised by Trixie's sympathy before seeing why.
"Ha. I can't believe the only other person who believes us is the one I called a manipulative showboat," Cherry scoffed before she realized what she said. "Sorry."
"I took it as a compliment," Trixie replied as she stood up with a smile. "Let me help you find the Stone."
"What's in it for you?" Sunset asked her.
Trixie smirked while glancing to her poster.
"Oh, no, no, no, no, no, no, no, no, no, no way, uh-uh, forget it." Atticus told her.
"Well, if you'd rather go on with Sunset Shimmer being the Biggest Meanie, that's fine by me." Trixie smirked.
"Fine." Sunset, Flash, Atticus, Mo, Cherry, and Patch groaned.
"So, where should we start... Partner?" Sunset forced herself to ask.
"How about with what I call you?" Trixie replied. "I'm thinking the Great and Powerful Trixie's... Pretty Decent Assistant-Detective-Helper People."
"That's a little long." Mo said.
"Might as well kick it." Cherry shrugged.
They soon came into the cafeteria.
"A cafeteria full of suspects, two detectives, and only one Memory Stone," Trixie told Sunset and the others. "Seems impossible, but so does pulling a rabbit out of a hat, and I do that all the time. Let's talk motive. Who here hates you enough to erase everyone's good memories of you?"
"If you go back far enough... Everyone." Sunset sighed.
"'Known Enemies: All'." Trixie wrote that down.
"Helpful." Cherry deadpanned.
"Let's start questioning." Patch said.
"How can we ask someone when no one remembers nice Sunset like we do?" Cherry asked.
"Good point." Patch said.
"We shall go to the nurse about the memory problems." Trixie decided.
"Can't believe I'm saying this but okay." Patch said.
They soon went over to the Nurse's Office.
"G-G-Good afternoon, ladies and gentlemen," Nurse Redheart smiled to the students. "Y-You feeling okay?"
"Why are you stuttering?" Mo asked.
"Mo, that's rude." Cherry scolded.
"That depends on how well you answer my questions," Trixie told the nurse. "Has anyone come in complaining of memory problems in the last few weeks?"
"Not that I can recall-" Nurse Redheart replied.
"You can't recall?" Trixie gasped. "We're too late!"
"Okay, this isn't going to help us at all." Patch said.
They soon came to ask about the Memory Stone and came to a student who knew a lot about rocks.
"Is there anything you can tell us about it?" Sunset asked. "Anything at all?"
"I can't tell much from a drawing." Maud Pie replied in a dry monotone.
"Thanks anyway." Mo said.
"Only that it's felsic-intrusive igneous, granular in texture, most likely arranged in an equigranular matrix, with scattered biotite mica and amphibole, at least 65% alkali feldspar by volume, with a melting point of 25 centigrade, plus or minus ten degrees," Maud Pie continued. "Sorry I couldn't be more helpful."
"Heh... Thanks, Maud..." Cherry smiled sheepishly to Pinkie Pie's total opposite sister.
They were soon in the yearbook room.
"Oh, stop looking at that," Trixie told Sunset. "You're just going to wind yourself up. You can't think if you're wound up. Oh, think, Trixie!"
"I wanted to come in here and see who we're missing," Sunset sighed as she looked through the photographs of students who had checks on them to narrow down their search, but only one had been unchecked which was an unpictured student. "But we've talked to everyone, A to Z."
"Wait, we haven't questioned this student yet." Flash Sentry said as he pointed to Wallflower Blush's picture in the yearbook.
"Wait... 'Not pictured: Wallflower Blush'," Trixie noticed. "Who's Wallflower?"
"I'm right here, you know." Wallflower replied as she appeared from seemingly nowhere.
"How long have you been there?" Mo asked.
"Long enough..." Wallflower slightly glared. "And Trixie Lulamoon, I've known you since third grade."
"Ahh! I remember third grade," Trixie smiled nervously. "Not you specifically, but what a grade it was. The Great and Powerful Trrrrixie debuted her disappearing frog trick. You know, a lot of people don't realize how much work goes into raising tadpoles. You really have to coddle them-"
"Not the right time." Cherry whispered to Trixie.
Sunset's book soon glowed and vibrated.
"Princess Twilight has an answer!" Patch replied. "It's so weird to call her that, I know she's a princess, but she'll always be Twilight to me."
Sunset soon opened her book to read what Twilight had found out.
"'Guys, we think the Memory Stone was buried under this rock formation'," Twilight's voice read through her note. "'And if you don't destroy the Memory Stone by the time the sun sets today, all those memories will be erased forever'."
'This is bad.' Mo thought to herself.
"No pressure..." Cherry smiled nervously. "What's the worst that could happen?"
"But how are we supposed to find this?" Atticus asked as he looked at the rock formation in the book.
"I think I found it." Mo said.
"WHERE?!" The others asked.
Mo gestured to the screensaver on Wallflower's computer.
Sunset soon decided to ask Wallflower about it. "Can I ask a silly question, Wallflower?" she then came to the metaphorically invisible girl. "Where did you take that lovely photograph?"
"Oh. That's my garden. Well, the school's garden, technically," Wallflower explained with a small smile. "I'm the president of the Gardening Club. I founded it, too. I'm also the only member. And the only one who's ever been to the garden. Or seen it. Or even asked about it."
"Who are you again?" Trixie asked her.
Cherry bore a deadpan look on her face as that question seemed inappropriate right now.
"I was maybe going to add this picture somewhere in the yearbook," Wallflower said, deciding to ignore what Trixie said. "What do you think?"
"We think it's nice." Flash Sentry said.
Sunset smiled politely in agreement.
"Sorry, Sunset doesn't let anyone put things in her yearbook," Trixie told Wallflower. "No matter how much they deserve them."
Cherry soon tackled down Trixie and covered her mouth. "Uh, no way, Wallflower Blush!" she then said with a nervous smile. "You should totally do that!"
"Yeah, totally." Mo added.
"Uh, so don't let us keep you from working on it." Sunset added.
"What?!" Trixie glared as she struggled underneath Cherry. "The Great and Powerful Trixie is... Annoyed and insulted!"
"Shut up!" Cherry whispered loudly. "Now is really not a good time for you to start complaining."
Wallflower soon began to type on her keyboard. Sunset stopped her by taking her hand.
"What're you-" Wallflower was about to ask.
Sunset then took a look into the shy girl's memories. Flash soon joined her so he could also see Wallflower's memories.
Twilight in her human form smiled as she walked with Flash while Wallflower stood by the bleachers in silence. The Cutie Mark Crusaders even came by, and their outfits would remind Cherry and the others of the episode The Show-Stoppers. There was then the party with Crystal Prep which would have Sci-Twi enroll into Canterlot High instead of staying at Crystal Prep. The next memory was shown her walking off alone. She looked rather upset and angry about being all alone in this whole school where everybody was a friend to each other.
She then found the garden and walked out to it almost as if it had been calling her name. And where it was perfect for her own garden. She was digging at one point and then found a small pouch filled with something and picked it up. She uncovered it and soon found the Memory Stone and it came with ancient Equestrian writing. We are then shown the yearbook room with her in the corner with the others talking with Trixie. After that memory, we are shown Wallflower alone in the room with the yearbook.
"Why should you notice me?" Wallflower sighed as she took a look at the yearbook as she sat in the dark before she then noticed The Memory Stone. "After all, you're Sunset Shimmer. Everybody loves you now. Why can't they see you haven't changed?" She then went into the garden, leaving the dark room.
Wallflower soon looked to the ancient writing as she held the Memory Stone and soon accessed its powers which would begin the whole adventure for everyone not affected by the Memory Stone. Sci-Twi, Pinkie Pie, Applejack, Rarity, Rainbow Dash, Fluttershy, and Mo were all fast asleep, and they seemed to have memory strips taken from their subconscious, and where all the memories were soon in the stone. Wallflower had an evil smile once she saw that the Memory Stone had been sealed.
Sunset and Flash's eyes glowed before they soon let go.
"You erased everyone's memories?" Sunset and Flash glared at Wallflower. They soon noticed that they both spoke at the same time.
"Uh... Yes..." Wallflower admitted.
"Wait," Trixie said. "Who are you again?"
The others face-palmed to this.
"You don't see me fitting in, I'm sitting here alone, Right beside my shadow, Always on my own~," Wallflower soon began to sing. "If I could share my wildest dreams, Maybe they would see, I'm more than just a wallflower, There's so much more to me~"
Atticus and the others looked a bit confused why she made everyone forget about the good things about Sunset.
"I'm invisible invisible a droplet in the mist, Invisible, invisible, it's like I don't exist~" Wallflower sang. "Right beneath my picture, This what you'll read, A laundry list of nothings~"
Cherry backed up and then ducked down before crawling towards Wallflower's backpack as she sang. Sunset saw what Cherry was doing and thought it as a smart idea.
"Now likely to succeed, A yearbook with blank pages, That no one wants to sign~" Wallflower continued singing.
Cherry soon reached out.
"A memory forgotten, Until the end of time~-" Wallflower continued until she glared to Cherry. "Hey, what're you doing?!"
"Uh... I dropped my glasses?" Cherry smiled nervously.
Wallflower was about to reached for her backpack first. Cherry and Wallflower soon fought for the backpack.
"Let go!" Cherry told Wallflower. "Sunset Shimmer doesn't deserve this!"
"She's right, Wallflower; and I don't even know you!" Sunset added.
"Exactly!" Wallflower glared. "You had everyone fooled, but now they know you're still... The Biggest Meanie!"
Cherry soon lost her grip on the backpack. Wallflower glared and then took the backpack away from her, making her fall flat on the floor.
"You're about to see how mean I can get!" Sunset warned Wallflower.
"Whoa! Whoa-whoa-whoa-whoa!" Trixie warned Sunset then. "Let's not antagonize the person with the all-powerful mystery rock!"
"I don't like confrontation," Wallflower glared as she brought out the Memory Stone. "Let's just... Forget this ever happened!"
"Stop her!" Patch barked.
"Don't erase-" Sunset begged, but it was too late.
WHOOSH!
"Huh? What was I saying?" Trixie asked before smiling before looking at the clock in shock. "I'm sure it was something brilliant. Also, how is it already 3:00?"
"When did we get in here?" Flash asked.
"Guys, the door's stuck, it won't open!" Atticus said as he jiggled the doorknob.
"Why won't it open?!" Mo gasped.
"I... Don't remember..." Sunset muttered wearily.
"Atticus, do you remember?" Mo asked.
"I don't..." Atticus admitted.
"Oh, this is bad." Patch said.
"Is anybody out there?" Sunset cried out as she banged on the door. "Somebody open the door! If we don't get outta here and figure out who has the Stone, in a few hours, it'll be too late to restore everyone's memories. I'll lose my friends forever."
"How are we supposed to catch someone who can erase our memory every time we get close to catching them?" Trixie scoffed.
Cherry soon tripped over something and brought out her journal which had notes from her dreams and what happened. "By being clever..." she then said once she had an act of genius.
"What's in your journal?" Flash asked her.
"'Check Sunset's video'." Cherry read aloud.
"Smart thinking." Atticus smiled.
"Yes!" Sunset smiled once she took a look. "It's been recording this whole time!"
"Twilight's camera?" Trixie asked. "What are you talking about?"
"I don't remember doing it, but I must have realized our memories would get erased, so I pressed record!" Cherry replied as she looked through her journal. "Also, apparently I dreamt about Wallflower Blush while Atticus and I met Captain Zoom."
They soon pressed play on the recording.
"Who's that?" Trixie asked about Wallflower.
"Wallflower Blush." The others told her.
"Name's not ringing a bell." Trixie shrugged.
Wallflower's song was soon heard.
"Ugh..." Trixie rolled her eyes and fast-forwarded through the song which took a while. "Long song, huh?"
"You said it." Cherry said.
The video then showed Cherry and Sunset both confronting Wallflower.
"She's kinda right about you." Trixie said uneasily about Sunset when Wallflower called her 'Biggest Meanie'.
"I can't believe I'm saying this, but I agree with Trixie." Mo said.
"Ah, The Wise and Moralizing Trixie was making a good point." Trixie replied.
"Don't push it." Mo said through her teeth.
"Sorry." Trixie smiled nervously.
"I didn't!" Sunset glared to the others. "I wasn't mean to her at all!"
"But maybe it's not good enough to not be mean to someone," Trixie advised. "Maybe you have to be nice."
Atticus, Mo, Patch, Cherry, and Flash were jaw-dropped as Trixie was right.
"You're right," Sunset sighed. "Not that it matters. I'm still trapped in here. Unless you can magic us out of here."
"Ooh, what's the point in trying?" Trixie sulked. "You've seen enough of my tricks to know what'll happen."
Atticus was surprised to see Trixie give up.
"At least when the sun goes down and everyone hates me forever, I'll still have some friends in the morning." Sunset sighed.
"Aw, Sunset." Flash smiled to that.
Atticus soon had an idea and soon smirked.
"What's up...?" Cherry asked, uneasily due to his smirk.
Atticus soon whispered his idea to her.
"Oh, boy..." Cherry sighed. "Are you sure?"
Atticus nodded to her.
"Fine..." Cherry replied. "We better hope this works."
"What?!" Patch asked. "We better hope what works?!"
"Here it goes!" Atticus said as he soon did what he planned to do. It was to raise Trixie's confidence in her magic tricks.
Cherry looked deadpan while Atticus did what he said he was going to do, and soon, the idea came into action.
"Oh, Trixie, you surely are the Greatest and Powerfullest Canterlot High School has to offer." Atticus stated.
Patch, Mo, Flash, Sunset, and Trixie were confused why Atticus said that until Sunset caught on.
"You're right, Atticus, we can't complain." The fiery-haired girl soon added.
"You poor fools!" Trixie replied. "You actually believed me when I was pretending to give up? Mere stage banter! The Great and Powerful Trixie never gives up on herself... Or her friends. I mean, her Pretty Decent Assistant-Detective-Helper People."
Patch smiled as Trixie got her confidence back.
Trixie then threw smoke bombs, but when she did, only she was out, she then threw another smoke bomb, but then she was inside and the others were out. This seemed to go on for a while.
"Okay, this is getting annoying." Atticus said before breaking down the door.
"Or you could do that..." Cherry replied before yelling. "Now, Atticus... Buddy... WHY DIDN'T YOU DO THAT BEFORE?!"
"MORONS!" Cherry yelled, nearly like Carface. "I'm surrounded by MORONS!"
"Come on, we better hurry before it's too late." Mo told the others.
They soon rushed off to go where Wallflower Blush was which was outside of the school.
