Prologue

After Mal and Ben became King and Queen, they thought everything was perfect. How wrong they were.

While they were celebrating, the dead remmants of Sunset Shimmer rose, to form a hideous monster, Demon Shimmer.

And now, only one boy, Flash Sentry, might be able to solve this.

Because, what is love, truly?

Carlos's mom

Cruella looked at her son in shock. “You want to become a vet?!” she screeched, her harpy like voice rising above the noise of her car.

“Yeah,” said Carlos. “Mom, this is Jane, my girlfriend. She’s Fairy Godmother’s daughter.”

“You’re dating an Auradoner?!” screamed Cruella de Vil. “You... you son of a bitch!”

Carlos gasped. “MOM!” he cried.

“You’re no son of mine.” she hissed. “I won’t come.”

Jane shrugged at Carlos, before heading back to Auradon.

“I’m sorry,” said Carlos. “My mom. She’s...”

“Don’t worry.” said Jane. “I understand.”

Alone

When Twilight Sparkle first joined Canterlot High, the one thing she did not expect was a demon friend. Sunset Shimmer.
They always used to hang out together, laugh, joke, and even grin. But the only thing she never told was her secret. Twilight knew that Sunset was bad, and turned into a demon. But she never told her why, or for that fact, when.

But that was a long time ago, when she was still alive. For the first time, Twilight felt loved, and had a friend. But now, she felt alone again. Since she died.

Twilight sighed, taking out the vial with the memory stone incident out. She slipped it into her pocket, zipped it up, before leaving her house.

She looked out at the horizon, towards Auradon, seeing that it was in danger, and Sunset was heading there to control the innocent people. She could see Mal, in dragon form, trying to defeat her, but was failing. What did AJ say?

Sunset was the most powerful demon in this world.

bringing sunset back

“Sometimes it’s hard to find yourself, but it’s worth it in the end
Cause in your heart is where it all begins...” Mal and Ben

It was nearly sunset in Auradon, and Flash Sentry and Twilight Sparkle were checking everything.

“Flash. Pour all the memory into her mouth. If she remembers it, do what ever you have to do, but if she doesn’t, well...”

Flash nodded. “I’ll do just that.”

Flash ran into the yard, shielding his eyes against the powerful magic.

“Sunset!” he shouted. “Please, I need to talk to you!”

The demon turned, to see Flash Sentry.

Flash nodded at Rainbow and Fluttershy to hold her back, as he poured the memories of her back in.

The colour of her skin lightened to pink.

Flash now had a decision to make: Would the thing he wanted the most bring her back?

He decided to take a risk. Flash looked at Sunset with determination.

“Sunset, you were never like this! I always believed you could change, I was right! During cotillion, I wanted to propose to you. I would like to do it now, so will you marry me, please? Don’t you remember, all the good times we had together?”

“Flash! You have to force her!” shouted Rainbow Dash.

Flash sighed. He didn’t know what to do. “Kiss her!” shouted Rainbow.

Flash nodded. He still loved her, and he shut his eyes, before kissing her.

After about a minute, he opened it, to see an almost transformed Sunset Shimmer. Maybe apart from the demon wings and the fangs, she was the girl he knew.

“Flash. I’m so sorry!” she cried. “I didn’t mean to hurt anyone! It was like the dead parts of me reignited into my ex form!”

Flash smiled. “It’s okay. I’ve been meaning to ask you for a while, will you marry me?”

Sunset smiled, truly, for the first time. “Yes.”

Then everyone cheered.

Author's Note

that’s the end of the story

Chapter 1: Sunset rises

Auradon was rather quiet today, as almost every inhabitant was sleeping. Well, all, but Rainbow Dash. But the sky, usually a royal navy blue, turned red.

Rainbow gasped, as she saw a familiar streak of red-gold hair rise, in pieces. Finally, came red bat like wings. A monster was formed, a monster she hadn’t seen since the fall formal, Demon Shimmer.

Rainbow shook Flash awake, as he looked out of the window, seeing his ex, well, may be, in her monster form.

Flash sighed. “We have to stop her.”

Rainbow nodded. “Sure.”

The return of Sunset Shimmer(fully)

Flash Sentry awoke to the sound of cackling. He opened his curtains to see Sunset Shimmer, well, what used to be Sunset Shimmer, wreaking havoc. In his heart, he knew he still loved her, and he would do anything to save her, and bring her back to life.

Flash pounded on each of the mane 6’s doors, to come with him, to try and fight her.

“Flash.” said Twilight. “You can’t. You have to show her.”

Now Flash was faced with a problem: What memory would he use to bring her back?

Flash and Twilight were in Twilight’s lab, back in Canterlot. Over by the window was a test tube rack, full of test tubes, with bungs containing what was inside them.

Inside these test tubes were memories of what they did together, the first contained the memories of the friendship games. The second contained the memories of the camp everfree. The 3rd contained the dance contest. The 4th contained the filming of the Daring Do. The 5th contained the Starlight adventure. And the 6th contained their most recent adventure, the Memory Stone.

Twilight leaned back on her chair, tutting loudly. “What do you propose we use to return Sunset back to normal?” she asked.

Flash sighed. “The memory Stone or the Games,” he said. “Or Everfree, thinking about it.”

Twilight grinned. “But first, we need to find her.”

hopes and dreams

Flash Sentry woke up in his Auradon dormitory, with Ben. “Hey, Ben.” he said.

“Flash, we have to stop Sunset!” cried Ben.

Flash was facing the window, tears glistening in his royal blue eyes. “What’s wrong?” asked Ben.

Flash turned to him. “Sunset. I was going to propose to her on the yacht at Cotillion.”

He returned staring out of the window, thinking.

Flash met Sunset at the top of the stairs, before heading onto the ship. He held her hand. Together, they walked down, onto the deck, where they were met by Evie, Jay and Carlos.

“How you feeling?” asked Applejack. “Ah heard ya passed out.”

“I did.” she said. “I only passed out because I realised what I had done. Demon Shimmer spoke to me while fighting.”

“Oh dear,” said Twilight. “Midnight still talks to me.”

“You feeling okay?” asked Applejack. “I sure hope you are. Cause if ya do feel faint... then just let us know.”

Sunset nodded. “Sure.”

They watched Mal, Ben and Uma come down. And Jane told Lumiere to reveal Ben’s masterpiece.

“No. No. NO!” shouted Uma, angrily. “What about me?!”

Sunset shot Uma a look of warning. Ben gave her his ring. Mal went right up to him and kissed him.

Uma growled, before jumping into the sea.

“NO!” cried Sunset, as the water splashed over everyone, including her. Water kills her.

Sunset couldn’t bear the pain. It was like her skin was peeling off, burning. “No, Uma!”

Mal’s eyes glowed green, as she swayed side to side, trying to balance. Mal rose up, purple smoke rising, as she turned into a dragon.

She was weakening, slowly. The pain was too great. She couldn’t even stand up.

Flash grasped her arm, well, what was left of her.

Sunset collapsed. Her eyes fluttered closed. “Flash.” she said. “I love you.”

Those were her last words before she died.

“No.” said Flash, sobbing. “No, please. Come back. I- I love you too.”

It was like Flash had lost a part of himself when she died. Like a part of his personality died, inactive, asleep. Whatever.

He had to defeat her, bring her back to life.

Because for the first time in his life, what is love?
