A corrupted wedding

Shining Armor was playing with his medallion of the guard, until Twilight knocked on the door.

"Twilly! Come in." Shining Armor opened the door to let her in.

"Your big brother's looking pretty good, don't you think?" Shining asked his sister.

"We need to talk." Twilight told Shining.

"About what?" Shining asked Twilight.

"Have you noticed your bride acting...... Weird?....." Twilight asked her brother.

"Well, a little bit. But she's probably just coping because of Discord, it's stressful times right now and she's probably got a lot going on right now." Shining assured his sister.

"But all I'm saying is that-" Twilight was interrupted by Cadance.

"Oh, I'm not interrupting anything, am I?" Cadance asked the two siblings.

"No, no not at all.........." Shining assured his bride.

"Good, because there's something I need to talk to you about, in private........" Cadance told her fiance, as she went inside the broom closet.

"Better see what she wants." Shining told his sister, as he went inside the closet.

Twilight couldn't help but sneak and eves drop on what they were talking about.

"Listen, you need to not wear that silly medallion." Cadance told Shining.

"This was my favorite uncle's." Shining told Cadance.

"'Was'. Just take it off." Cadance told her groom.

"I'm wearing it at the wedding." Shining protested.

"Perhaps I don't make myself clear." Cadance stated, as Shining suddenly felt woozy and slow.

"You will not wear that medallion at the wedding." Cadance commanded Shining.

"I will not wear this medallion at the wedding." Shining repeated like a robot, as he took off the medallion and threw it in the trash bin.

Twilight couldn't believe what she was seeing, Cadance had some kind of grip on Shining's mind!

"There, that's better." Cadance stated, as Shining slowly regained his senses.

"She's not just unusual and strange, she's downright evil!" Twilight quietly exclaimed, as she ran off to warn her friends.

"Twilight?" Shining called out to his sister as he saw her running through the door.

"Let her go." Cadance told her groom, as she gently rubbed her head on his shoulder.

Shining merely stared at the door in contemplation..........

Twilight ran into her and her friend's room as she tried to warn them.

"Shining Armor's in danger! We have to help-" Twilight halted her speech when she saw her friends wearing dresses.

"Can you believe it? We're gonna be Princess Mi Amore Cadenza's new bridesmaids!" Fluttershy exclaimed with glee.

"What happened to her old bridesmaids?!" Twilight asked.

"She didn't say, she just stated to us that it would be absolutely wonderful to fill in for them." Applejack stated.

"Oh, I can't wait to be part of the wedding!" Pinkie Pie cheered.

Twilight merely stared in desperation, before slowly walking out the door.

"I really am all alone........." Twilight lamented, as she head out to figure out how to save her brother.

Later................

The ponies plus Spike were now practicing the wedding rehearsal, as the mane 5 headed inside the hall.

"Perfect girls, no need to rush." Celestia assured, as some of the ponies giggled to themselves.

"Then of course, Cadance will enter." Celestia stated, as the guards opened the doors to let Cadance in.

As Cadance approached the alter, Celestia gestured Shining to get the ring from his best mare.

However, they noticed that Twilight wasn't in the room.

"Wha- where is Twilight?" Shining asked the ponies, until the doors opened.

"Right here!" Twilight announced as she barged into the room.

"I'm sorry, I don't why she's acting like this." Shining told his bride.

"It's ok, maybe the rehearsal can still happen WITH her." Cadance suggested.

"No! There is no rehearsal! Because there is no wedding! Because SHE'S, EVIL!" Twilight pointed an accusatory hoof at Cadance, earing several gasps from several ponies.

"She's acted suspicious towards my friends, she's obviously done something to her bridesmaids, and if that wasn't enough, she's able to command Shining to do her bidding through brainwashing!" Twilight stated to everypony, as all of them looked either shocked or angry.

"There is something wrong with her, and I'm not going to let her hurt my brother!" Twilight exclaimed, as she cornered Cadance to a wall.

However, Cadance merely sobbed.

"Wha- why I would never! Why are you doing this to me?" Cadance exclaimed, as she burst out of the room in tears.

"Because you're evil! EVIL! And if I don't stop you, you're going to ruin my brother's life!" Twilight lashed out at Cadance from across the hall.

Everypony looked on in shock at Twilight's outburst.

However, Twilight was soon met with a very angry Shining Armor.

"You have some nerve little filly, I dropped my medallion because I knew arguing wasn't getting anywhere. And she decided to replace her bridesmaids because she found out the only reason they wanted to be in the wedding was to meet Canterlot royalty! And the reason she's been acting weird towards your friends, was because with everything going on at the moment, she's been distracted trying to FOCUS for the wedding! And yet you accuse her of being awful when all she's tried to do is be my bride!" Shining Armor lashed out at his younger sister, who was on the verge of tears over his argument.

"Now, I'm going to comfort her, while you stay out of my wedding." Shining coldly told Twilight, as he left the room to comfort his bride.

Twilight looked back at her friends, who slowly approached her........

"You need some time to calm down Sugercube." Applejack told Twilight, as she and the others left to comfort the bride as well.

"I hope you're happy." Celestia coldly stated, as she left with the others as she shut the door.

Twilight was on the verge of tears, as she was left alone at the alter.........

"Maybe I was being paranoid.............. Maybe Cadance wasn't the one trying to ruin the wedding............. Maybe I was just trying to have my brother all for myself...................." Twilight lamented, as she sobbed on the floor uncontrollably..........

However, she soon heard hoof steps, and she felt a hoof gently rub her head, as she saw Cadance comforting her.

"I'm so sorry." Twilight desperately apologized.

However, Cadance's warm smile slowly turned into a small frown.

"You WILL be." She threatened, as Twilight felt something grabbing her leg.

To her horror, she turned around to see that the ground itself was dragging her into it, and pulling her inside the floor.

Cadance merely watched with a malicious smile.

As Twilight was consumed by the ground, Cadance turned around with a wicked smile on her face.
