"So, let me get this straight," Sunset started. "You told Trixie to forget about something, your markings glew, and next thing she knew Trixie couldn't remember that thing?"

"Yeah, and when I asked her if she remembered, the process rewinded the memory back to her," Wallflower added. "I think that's the way the markings work."

"From the way you speak, it seems Trixie was of help. And she says, your welcome."

"Don't be so calm yet, Trixie," Wallflower said. "I still need to show Sunset how the process works."

"Trixie insists that, even though Trixie's so Great and Helpful, she shouldn't be a guinea pig anymore."

"We weren't going to use you as a guinea pig, Trixie," Sunset said. "Still, we need someone to use Wallflower's powers on. And I don't think she can use them on herself."

Wallflower looked at the ceiling anf scratched her chin, humming with curiosity before Trixie grabbed her arm and dragged her.

"Alright, we're going out before you get any crazy ideas."

Sunset, Wallflower, and the Great and Third Wheel Trixie walked down the streets, Wallflower barely getting any eyes on her despite her notable markings.

"You know, I had the feeling I was going to become the center of attention with these things," Wallflower pouted and folded her arms. "But it seems nobody minds."

"Trixie suggests your forgetability is to blame."

"Wallflower doesn't appreciate the sass!"

"Sunset might have found the perfect candidate!"

The girls paused to get their syntax back in place, and they turned to Sunset's target: a certain purple dog digging on the ground, Spike.

"Isn't that Twilight's dog?" Wallflower asked, before growing excited at a potential implication. "If Spike's here, then Twilight must be nearby!"

"Or Fluttershy, or any of our other friends taking him out for a walk," Sunset added. "Spike doesn't always equal Twilight being around."

"Aw."

"Oh hey girls!"

The girls flinched and looked at Spike as the dog walked to them, Wallflower looking particularly flabbergasted as she said:

"Did the dog just talk?"

"You get used to it after a while," Spike answered. "Anyway, is there anything I can help you with?"

"Yeah," Sunset wrapped her arm around a blushing Wallflower. "My friend Wallflower here gained strange memory powers and I need someone to test it out-"

"And your first option was a talking dog?" Spike asked.

"Trixie has to agree with the puppy: using those powers on a human is problematic enough, using them on an animal would get Wallflower scorn from everyone!"

"Not if she asks first," Spike added. "Do you want to do this?"

"I guess, but do you want to?" Wallflower scratched the back of her head. "We can always look for someone else."

"Nah, It's fine," Spike tapped the ground. "Twilight went off to test someone else and she left Fluttershy to take care of me, but she got sidetracked watching some swans, so I got nothing better to do."

Wallflower eyed Sunset, who gave her an approving nod. Then she turned to Trixie, who did the same.

Wallflower promptly walked to the dog, crouched down, and said:

"Spike? Forget about..."

Wallflower paused and got an idea.

"Forget about how to talk."

Light came out of Spike as the markings glowed and absorbed it, turning purple in the process.

By the time Spike turned to normal, he tried to talk... And all he let out were little barks.

"Fascinating, okay, remember how to talk!"

The light came out again and returned to Spike, turning everything back to normal.

"Whoa-ho! That was weird!" Spike said, putting a paw on his cheek. "I haven't felt like that since before the friendship games!"

"Okay, so, from the looks of it," Sunset said as she walked to Wallflower's side. "You can manipulate memories to the extent you can alter certain things; telling someone to forget how to talk would turn that person mute."

"It works for dogs," Wallflower said as she brushed Spike's head. "It might work for humans..."

Wallflower frowned, and Sunset extended a hand forward. "Let's go test something else before you think too much about that."

Wallflower grabbed Sunset's hand... And everything went black.

"Wallflower?!"

Wallflower opened her eyes, but she was no longer at the park.

In fact, she wasn't anywhere in Other-Questria, as far as she could tell.

She was at a pitch black void, decorated with rectangular screens showing events... Seemingly playing out from Sunset's point of view.

The Fall Formal, the Pillar, Snips and Snails' transformations, even stuff after that like the Battle of the Bands and Camp Everfree. Not that Wallflower recognized the latter two.

"Where am I?"

"Welcome, visitor!"

Wallflower turned around, and to her shock, she saw a girl sitting on top of a pitch black throne.

The girl kinda resembled a daemonette, with cherry red skin, black sclera with blue eyes, claws, a red-yellow flaming dress with black boots, demonic wings with holes, pointy ears, and red-yellow hair in the shape of a flame.

That's the order of things that caught Wallflower's attention, apparently.

"Welcome to Sunset Shimmer's Memory Dumpster!" the demoness greeted. "We don't get visitors very often, you may feel honored. Or disgraced, either one works."

"Either one works?" Wallflower parroted. "Who even are you?"

"I'm Sunset Shimmer, sweetie. A past version of her anyway," the creature spoke as she stood up and approached Wallflower. "However, having the same name as her... I don't like the idea of that. So, I decided to give myself a different name."

The demon paused until she reached Wallflower.

"You may call me... Sunshine Luster."

"Okay... Sunshine Luster," Wallflower clenched her fists. "Where are we?"

Sunshine snapped her fingers, transforming the void from pitch black to an odd grey, with one strange revelation: the rectangular screens hanging around?

Sunshine and Wallflower were standing of a pile of them, shaped like the floor.

"Like I said, this is Sunset's memory dumpster. The place where Sunset throws away and forgets certain memories."

Wallflower winced at the mention of "forgets" and began searching the floor of memories...

"Looking for memories about you?" Sunshine asked, grabbing and pulling Wallflower up. "Sorry to tell you this, but look up."

Wallflower reluctantly obliged, and the rectangular screens changed, showing events related to herself. A picnic, a date, their first meeting, their actual first meeting....

"Sunset hasn't forgotten about you since you two made peace," Shine bitterly stated. "Now, if only she could make peace with herself in the same way."

Wallflower looked at Sunshine. "What do you mean?"

"Do you really think I'm here because she forgave herself? No!" Sunshine dropped Wallflower harshly. "I'm here because Sunset would rather forget about what she did than try to make peace with it! I gave her a couple nightmares to see if that would work, but that just resulted in her seeing therapy and looking me away with the rest of these dead memories."

Sunshine turned around and folded her arms. "Now, I'm stuck here, watching how Sunset lives her life."

Wallflower paused. "Do you know how to get out of here?"

"Pst, sure, anybody but me can get out; just last week someone named Pinkie Pie stumbled upon here and left just as quickly."

"Well, then I have an idea," Wallflower stood up and dusted herself. "In exchange for helping me get out of here."

Wallflower flashed a confident smile. "I'll help you and Sunset make peace."

Sunshine raised an eyebrow, but her confusion turned into joy as she realized what this meant...

"Wallflower, come on, wake up!" Sunset shouted as she shook her unconscious body. "Please, wake up!"

"Trixie thinks It's not working."

"Sunset thinks if you're not going to help, then buzz off!"

"Wallflower... Thinks... You're too loud..."

Sunset, Trixie, and Spike-yeah he was still there-turned and saw Wallflower slowly open her eyes and flash a smile.

This was before she stood up, put a hand on her chest, and took a couple steps away form the group.

"Wallflower, wait!" Sunset called. "What happened?!"

Wallflower stopped, slowly turned around, and with a straight smile she said:

"I landed in your memory dumpster, met your evil self, and got out in exchange for helping you make peace with it."

Before anybody could process what Wallflower said, she groaned in pain and lowered her head, covering her face as from her back, the same demonic hole wings of Sunshine sprouted from her back.

"W-Wallflower?" Sunset stuttered.

Wallflower's hair grew bigger and wilder as red streaks spread from the top down to her quills.

"What's going on?!" Spike asked.

"Trixie's scared!"

Finally, Wallflower raised her head to reveal the final changes: her markings were red with yellow lines, and her sclera had turned black.

This, along with Wallflower's worried expression, made Sunset realize what had happened...

"Wallflower, what have you done?"

Author's Note

Sunflower Blush, everyone? Or I don't know, what other name do you have for Wallflower's form in the end?
