A corrupted wedding

Twilight and her friends sat on a picnic on a beautiful sunny day, just enjoying themselves and spending time as friends.

"What a beautiful day, wouldn't you agree girls?" Rarity asked the ponies.

"It is quite lovely." Fluttershy replied with a warm smile.

"Sigh, couldn't we have chose to do something more exciting?" Rainbow Dash asked, bored out of her mind.

"Dash, you know we can't all go to see the Wonderbolts perform their stunts. Not all of us can walk on clouds." Applejack told Dash.

"You know I meant something else AJ!" Dash protested.

"Let's just be glad we were all able to take time out of our day to enjoy this beautiful sunny day." Twilight told her friends.

However, they were soon approached by Spike rushing over to the picnic.

"Twilight, I have a message for-" He burped out a letter for Twilight to read.

Twilight opened the letter.

"'Dear Twilight, I am sure you are as excited as I am for the upcoming wedding in Canterlot.' Wedding?" Twilight read out loud to her friends.

"'I will be presiding over the ceremony, but would very much like you and your friends to help with the preparations for this wonderful occasion. Fluttershy, you will provide the music with your songbird choir, Pinkie Pie, you will host the reception, Applejack, you will be in charge of the catering for the reception, Rainbow Dash will perform a sonic rainboom when the bride and groom finish their I do's, Rarity will design the dresses for the bride and bridesmaids, and Twilight, you will be making sure everything in the wedding goes as planned. Yours truly, Princess Celestia.'" Twilight read, before she examined the letter closely.

"But I don't understand, who's getting married?" Twilight asked.

"Oops, heh heh, I was probably meant to give you this one first..........." Spike sheepishly handed over another letter to Twilight.

"'Princess Celestia cordially invites you to the wedding of Princess Mi Amore Cadenza and' GASP, my brother?!" Twilight gasped, as she realized her brother was getting married to somepony she never heard of before.

"Well congratulations Twilight! You're gonna be a sister in law!" AJ congratulated her friend as she hugged her tight.

"Yes, to somepony I don't even know! Why didn't Shining Armor tell me in person that he was getting married?!" Twilight groaned.

"But this is still an important moment for him, the least you can do is be supportive." Fluttershy told Twilight.

"But Shining Armor and I have always been so close! Before I moved to Ponyville he was the only pony I accepted as a friend, and now he just suddenly decides to start a new family with princess Mi Amore ca-what's her face?" Twilight complained.

"Twilight, I know how much it means to you, and I know it's upsetting to have things drastically change like this, but I'm sure your brother has a good reason for not telling you personally. The least you can do is be there for him during his big day." Applejack told her friend.

"Sigh......... I guess you're right. I guess I'm just worried he won't have any time for me anymore now that he's going to have a wife..........." Twilight lamented to AJ.

"Twi, you're his sister........ He'll always have time for you." Applejack assured before giving her a warm hug, as Twilight embraced and hugged back.

"Come on Everypony! We have a wedding to plan!" Pinkie rallied her friends, as they headed to the train station to travel to Canterlot.
