A corrupted wedding

Twilight and her friends soon arrived at Canterlot. However, they noticed it was heavily guarded. Not to mention there was a giant shield protecting the whole capital.

"What's with all the tight security around the joint?" Dash asked.

"Perhaps they are taking extra precautions to make sure no one disrupts the wedding." Rarity speculated.

"Whatever the case, I'm going to confront him on why he sent me a piece of paper instead of himself!" Twilight huffed, as she headed inside the city to confront her brother, leaving her friends concerned.

Shining Armor was railing the troops to head to their posts.

"I've got something to say to you mister!" Twilight walked up to the castle, when the guards armed their spears at the unicorn.

"Twily! It's ok she's with me!" Shining assured the guard to lower their weapons, as he headed down to greet his little sister.

"I missed you so much I-" Shining was cut off by his sister.

"Why didn't you tell me in person that you were getting married?! Am I not that important to you anymore?......" Twilight asked her brother, as she teared up.

"Of course you're important to me! It's just that I need to ensure protection for Canterlot. For there's been a.......... Major, disturbance........." Shining Armor stated.

"What disturbance?............" Twilight asked her brother.

"Sigh................... Discord has escaped." Shining Armor dropped the bomb on his sister.

"What?! How?! And when?! Why didn't the princess send us to deal with him?! Where is he?!" Twilight bombarded her brother with questions.

"We don't know! Discord hasn't been seen since he broke out of his stone prison, we were ordered to protect Canterlot so that it wouldn't be tainted by his magic. Ponyville and the other corners of Equestria haven't been tainted, as I'm sure you know. But we don't know where he is or what he has planned.......... Which is why the princess selected me to protect Canterlot." Shining Armor told his sister, as he boosted his magic on the shield on Canterlot, which gave him a slight migraine.

"It is my duty to protect Canterlot to make sure it doesn't fall in ruin, my magic is the only thing protecting Canterlot from turning upside down. You understand, don't you?........." Shining Armor asked his little sister.

"I guess I do............." Twilight said, tearing up a bit.

"I guess, you could always be my best mare, if it could make you feel better." Shining Armor suggested, which gave Twilight a smile.

"I'd love to." She said, as she embraced her B.B.B.F.F with a hug...........................

"But I'm still pretty ticked you're marrying somepony I don't even know! When did you even meet this "Princess Mi Amore Cadenza?'" Twilight confronted her brother.

"Twily, Princess Cadenza, is Cadance." Shining revealed.

"Cadance? As in THE Cadance? As in the greatest foalsitter in the history of foalsitters?!" Twilight beamed happily.

"You tell me, she was your foalsitter." Shining chuckled.

"Oh my gosh oh my gosh oh my gosh! Cadance is only the most amazing pony ever! She's wonderful, she's innocent, she's generous! She's everything I could ever ask for in a foalsitter!" Twilight hyped up, as the scene cuts to show a flashback of Twilight and Cadance when they were foals.

"I'm so lucky to have you as my foalsitter!" A young Twilight told a young Cadance as she pushed her on a swing set.

"I'm the one who's lucky Twilight." Cadance assured.

"Please! You're a princess! I'm just a regular old unicorn....." Twilight lamented.

"You are ANYTHING but a regular unicorn." Cadance assured Twilight, as they began their signature dance.

"Sunshine sunshine! Ladybugs awake! Clap your hooves and do a little shake!" Twilight and Cadance sung, as they laughed. Happy to have each other no matter what.

The scene then cut back to the present.

"I can't believe you are going to marry Cadance! You're marrying Cadance! You're marrying Cadance! You're marrying Cadance!" Twilight jumped up and down around her brother, until she bumped into..........

"Yes? You called for me?" Cadance encountered Twilight for the first time in years.

"Cadance! Sunshine sunshine! Lady bugs awake! Clap your hooves and do a little shake!" Twilight sung, welcoming Cadance back after so long.

"Umm, what are you doing?........" Cadance asked Twilight, looking as though she never seen her before.

"Cadance it's me! Twilight!" Twilight tried to remind Cadance...........

"Right, Sorry Twilight but I don't have time to gallop in the sunshine right now, maybe some other time........." Cadance "assured" Twilight, as she walked over to her groom.

"What?............" Twilight muttered to herself........

"I'll be at my post, while Cadance checks in on the wedding preparations. I'm sure we all feel that it was wonderful that you and your friends get to spend this wonderful occasion with us, right dear?" Shining asked his bride for support.

"Why yes, dear........" Cadance assured her groom, as they both left to their rooms.

Twilight merely looked on, as she couldn't help but feel that something was wrong. She just didn't know what..........................
