A different sibling's wedding

Twilight tightened her dress, making sure it was fit for her big day, until she heard a knock on the door...

She opened it, and saw her older brother standing outside.

"Shiny! Come in!" She greeted with a smile.

"Your little sister looks pretty good, don't you think?..."

Shining did not respond.

"Is something wrong?" She asked.

"We need to talk, I think you're making a big mistake."

"Are-... Are you judging me?"

"No! I would never judge you! Twily, I want you to know that I'll always be supportive of who you decide to be with, it doesn't matter if it's a stallion or a mare, I'll still be proud. But that's not the point, I think there's something seriously wrong with Ca-"

He was interrupted by the mare herself coughing to grab their attention...

"Oh, hi sweetie. Hold that thought, what is it?" Twilight asked her soon to be wed.

"Could I speak to you for a moment, dear?"

"Better see what she wants."

"Ok... just, please be careful..." Shining begged his sister.

"I will." She assured, as she went inside the broom closet with her...

Shining Armor's concerns got the better of him, as he peeked inside the broom closet to see what they were talking about...

"Did you HAVE to wear a flower head on top of your dress?"

"I thought they looked pretty, and I thought you would like them."

"Well, I don't. So if you could just take it off..."

"And waste something I thought would look good at our important day?..."

"Are you disagreeing with me?"

"Yes! I-" Twilight suddenly begun to get an increasing headache..

"Oh dear, are you getting another of your headaches?"

Twilight fell unconscious, as she was blasted with green magic as her eyes swirled around dizzily.

Shining Armor could only watch in horror what happened to his little sister...

"Feeling better?"

Twilight gave a slight nod of conformation as she was lifted off the ground.

"She's not just unpleasant and rude... she's downright evil!" Shining quietly exclaimed, as he rushed to tell Twilight's friends the serious danger...

Twilight and her bride walked outside the closet.

"Shiny?" Twilight saw her brother rushing out the door...

"let him go."

"Weird, it looked like he had more to tell me..."

Meanwhile...

Shining Armor made his way to Twilight's friend's room.

"Twily is in danger! We have to help-!"

He paused when he saw they were all wearing dresses.

"Dresses?!"

"Can you believe it?! We're gonna be the new bridesmaids!"

"NEW bridesmaids?! What happened to the old bridesmaids?!"

"Cadance didn't say, but she said that she would just love, love, love it if we filled in for them."

"And you had your doubts about her."

"Oh! I can't wait to be a part of the wedding!"

"I guess I'm all on my own..." Shining merely looked down sadly, as he tried to find a way to save his sister.....

Later...

The rehearsal was in the middle of practice, as Twilight and her friends stood at the alter.

"Perfect girls, no need to rush." Celestia assured, as the bridesmaids giggled to themselves.

"Then of course Cadance will enter." Celestia stated, as the guards opened the doors to reveal the future second bride...

Twilight's eyes widened in happiness and anticipation...

The other bride then made her way towards the alter.

"I'll say a few words, and then we can begin with the vows."

They all paused when they noticed the captain was not present in the room.

"Hey, where's Shining Armor?" Twilight asked, as the doors suddenly opened right on time.

"I'm here! I'm not going to stand next to her! And neither should you!"

Twilight promptly cringed at her brother's embarrassing behavior...

"I'm sorry, I don't know why he's acting like this."

"Maybe we should just ignore him."

"You have to listen to me!"

"Are you alright there cap'n?"

"I'm fine!"

"Really? because?" RD was ignored as Shining continued with his rant.

"I've got something to say! SHE'S EVIL!" Shining pointed a hoof at Cadance, as Twilight stood in front defending her.

Everypony promptly chatted amongst themselves over the captain's accusations...

"She's been horrible to her friends, she's obviously done SOMETHING to her bridesmaids, and if that wasn't enough, I saw her cast a spell on my sister that made her eyes go all-!" Shining spun his eyes around crazily in demonstration.

Everypony could only stare, as Shining cornered Twilight's bride in frustration.

However, she merely begun to sob in tears.

"Why are you doing this to me?"

"Because you're evil! EVIL! And if I don't stop you, you're going to ruin my sister's life!" Shining Armor lashed out, as she ran out the hall in tears.

However, Shining Armor would soon find himself faced with a very angry little sister....

"I just can't believe you! You would really jump to conclusions because you're that cagey of me?! Do you want to know why my eyes went all-" Twilight mimicked Shining's demonstration from earlier.

"It's because ever since this whole wedding was being planned, I've been having intense stress bursts in fear that something may go wrong. Cadance hasn't been casting spells on me, she's been using her magic to calm me down. And the reason she decided to replace her bridesmaids, is because she found out the only reason they wanted to be IN the wedding, was so they could meet Canterlot royalty! And the reason she hasn't been on my best behavior with my friends, is because of you keeping the shield standing and me resting, she's had to make all the decisions on the wedding!"

"Yes but-" Shining tried to make an argument but it was futile.

"She's completely stressed out because she's trying her best to make sure our big day be PERFECT! Something that obviously wasn't important, TO YOU."

Shining tried to reach a hoof, but she denied it.

"Now if you'll excuse me, I have to go and comfort my bride. And if I were you... I wouldn't show up to the wedding..."

As Twilight left as Shining stared, the bridesmaids and Spike could only watch from a distance...

"Come on y'all, they both need our assistance..."

They all left to comfort their friend and her bride, as Shining stared glumly...

"I hope you're happy." Celestia dismissed her captain, as she left the room and shut the door behind her...

"Maybe I was being overprotective... I could've gained a sister... but instead... I lost my first and only one..."

"She was my little sister best friend... forever... But now we'll never do anything... together..."

As Shining Armor begun to cry, he soon heard hoof steps, as he felt a hoof gently rub his head and looked up...

"I'm sorry..."

Twilight's brides eyes flashed green...

"You WILL be."

Shining Armor's eyes widened, as he felt himself being pulled underground...

To his horror, green flames surrounded all over him, as he saw the bride merely watching with a sadistic grin.

As the captain was consumed by the floor, she walked away with an evil smile on her face...
