The Secret Alicorn

"Twilight, you're back!" Princess Cadance came running up. She gasped.

"Twily! Your... What did that monster do?" Shining Armor snarled.

"What?" Twilight asked.

"Your mane is turning silver." Shining Armor points out.

"She must've been right about accidentally hurting me." Twilight sighed.

"She's a monster!" Fluttershy hid behind Shining Armor.

"How do we reverse it?" Rainbow Dash asked.

"I think you have to find the magic of friendship-" Shining Armor began.

The girls gave a cheer.

"With the pony who did it." Shining Armor sighed.

The girls sighed.

"Rainbow Shimmer?" Rainbow Dash asked. "Seriously. Please tell me you're joking!"

"No, I'm not." Shining Armor looked serious. "Would I if my little sister's life was in danger?!"

"Ugh. We have to go back?!" Rarity whined. The others nodded.

"We're coming with you." Princess Cadance said. "Hop in, girls. Twilight, here's an extra blanket."

Once in the sled, Twilight sat in between Princess Cadance and Shining Armor in a blanket.  They were keeping her warm on the long journey to Rainbow Shimmer's magical ice castle adventure.

"Twily, you'll be okay," Shining Armor assured. "We'll get Rainbow Shimmer to unfreeze you or she dies."

"No!" Twilight wiggled out of Shining Armor's grasp. "You're not going to hurt her! She is our friend. Like you wouldn't hurt any of THEM-" Twilight pointed at the five girls in front- "Rainbow Shimmer is no exception!"

"You'll have to get through me, too." Rainbow Dash joins the conversation. "The last chance I got, I checked, and was still the Element of Loyalty."

"Okay, okay!" Shining Armor covered Twilight again. "I won't lay a hoof on her or use any magic on her."

Once at the ice castle after some very dull conversation, Rarity opened the door.  Rainbow Shimmer was nowhere to be seen.

"F- Follow us," Teilight shivered, running up the icy stairs towards the balcony they had been to earlier. And Rainbow Shimmer was in the corner of the balcony. She gasped when she saw the party of ponies.

"I said go away!" Rainbow Shimmer turned away. "That means all of you!"

"We're not going anywhere until you unfreeze my little sister's heart, you monster!" Shining Armor snarled. "Do it now and we will leave! Use the magic of friendship on her! It will make the ice melt!"

"I don't know how! Use the Elements? But I'm not one!" Rainbow Shimmer stepped out to the edge of her balcony. "Ask them! They're the Elements! But please just leave me be forever!"

"Are you sorry?" Fluttershy asks in a whispers.

"Yes, I'm so sorry, Twilight. Sorry that I accidentally hit you. Sorry that I was born with- with this!" Rainbow Shimmer casts snowflakes towards the out of her balcony, and not towards anypony.  "Excuse me." Rainbow Shimmer runs out the door.

"No!" Applejack snaps. She runs right after, the others hot on her trail.

The girls found her in another sparkly ice room with no balcony, just one door leading in and out. Rainbow Shimmer was staring at the ice. And she was crying.

"Um.... Rainbow Shimmer?" Twilight asks. "It's okay. I know it was an accident. I know that."

"Sadness swirls within me like the snow," Rainbow Shimmer sings. "I've frozen out the only friends I'd ever know. There's no way to win, but I wish that I had told them long ago..."

"Life's too short," Rainbow Shimmer and Twilight sang together. They looked at each other.

"To be such a very stupid fool, so reckless I couldn't see." Rainbow Shimmer sings.

"Life's too short, to be so desperate to know, that I only ever thought of me..." Twilight sang. "I wish I saw things clearly, I guess I'm just not the sort. Now All I know is..."

"Life's too short," both mares sang.

Bright yellow light appeared followed by blue light. Princesses Celestia and Luna appeared. Everypony except Princess Cadance bowed.

"Mother... Do away with me as you choose." Rainbow Shimmer hung her head. "I accidentally hit Twilight with my ice magic. I'm no use to Equestria if I'm able to harm ponies."

"Rainbow Shimmer," Celestia sighed, "You are special. Unique. And nopony should doubt it. Especially yourself. Your weather magic is special. But when you left-"

"Yeah, yeah. I KNOW! Equestria's covered in random weather patterns. Dangerous ones too." Rainbow Shimmer sighed. "And Twilight- I'm so, so, so sorry."

Luna sighed. She showed them the new Equestria. Thunderstorms, extreme heat, blizzards... Everything.

"Rainbow S- Shimmer," Twilight shivered, "I'm the Element of Magic, and I choose you to inherit my Element."

"Why? I've frozen you," Rainbow Shimmer sighed. "I'm a horrible friend."

"You have them," Twilight whispered. "You know what friends are like."

Twilight started to turn ice blue. Rainbow Shimmer gasped. She put her hoof on Twilight, who's mane was totally grey by now. Slowly, she was turning even more blue. Pinkie Pie even looked sad, crying while hugging Twilight.

Twilight was frozen. Because of Rainbow Shimmer. But then, Rainbow Shimmer added six magical words:

"You will always be my friend."

Twilight started to turn purple quickly. Purple! Her normal color!

"Twilight!" Rainbow Shimmer swept her into a hug. "I'm so sorry! True friendship survives!! But- but- but how?!"

"You said 'You will always be my friend.' That is a sign of true friendship." Luna smiled. "Without the Elements of Harmony. Looks like you still have a part of all the Elements in you still."

"Yeah... Guys, thanks for chasing after me. I'm sorry I didn't tell you. I just didn't want to hurt you like I did Glacier." Rainbow Shimmer sighed.

"Who's Glacier?" Rainbow Dash asked.

"Glacier.. Glacier was my little sister." Rainbow Shimmer sighed. "She was a pink pony with white mane and tail. Also an alicorn, but no weather powers. My dad was Winter Solstice.  I ended up with the powers. But one winter night, I was playing in the throne room. With my snow stuff. And then she and I were playing 'snowball tag.' I was it, and I accidentally hit her in the heart like I did to you, Twilight. But when Princess Celestia got there it was too late. We agreed to conceal my powers. Well, that's over!"

"I'm so sorry!" Pinkie broke into really hard sobs. "Hey, where's your crown? And princess stuff?"

"Um... I kind of vaporized them?" Rainbow Shimmer asked sheepishly. "Oops?"

"Maybe we should have another Coronation Day again." Princess Celestia smiled. "And stop the weather?"

"Okay!" Rainbow Shimmer ran downstairs, and her friends followed. "Are you ready?"

"Woo hoo!" Pinkie Pie screamed.

Rainbow Shimmer raised a hoof to the sky. She then moved it and pointed at her ice castle. It started to melt from the top. Eventually, it melted the entire thing. Just like Rainbow Shimmer commanded.

Princess Celestia teleported Shining Armor and Princess Cadance to the Crystal Empire. Then, she teleported everypony else to Canterlot- where there was a blizzard! Standing on the palace steps with her friends, she thought about sunny weather everywhere. Soon, it became a bright sunny day.

"What were you saying about Coronation Day number two?" Rainbow Shimmer asked, grinning.
