All the ponies in the wedding place were looking around and they were like "wuh?" and "OMFC!" and "we didn't expect this to happen at all! well, maybe we expected Celestia and Twilight, but not Buttonmash and Scooterloo!"
Princess Diamond Tiara and Silver Spoon were looking at each other and they didn't know what to do. No pony knew what to do. The wedding pony that was doing the wedding didn't know what to do either. Normally no pony objected to a wedding so she didn't know what to do when a pony did, and especially when four ponies did including two princesses.
Unexpectedly a fifth pony stood up from the crowd. A bright green pegasus with a long, flowing brown mane and tail. "Who are you?" somebody asked and the pegasus replied, "I am Shade. And I am le shipping goddess! I can help you!" and everypony's jaw dropped.
The pegasus continued, "Princess Twilight, Princess Celestia… can't you see that you two are perfect for each other?"
"Ewww!" asked Twilight. "She's like thousands of years too old for me."
Shade laughed. "You're talking about the most powerful alicorn in Equestria. Princess Celestia, surely you know how to perform an age spell."
"Why, yes!" Celestia queried. "I can make Twilight as old as I am!"
"I was more thinking you could make yourself a bit younger. That's clearly how she likes 'em," asked Shade.
Celestia waved her magic horn in the air and recited the magic words: chronius regressium! and then she became a little filly. "Yay!" said Twilight and wrapped her arms around the pink-haired foal, kissing her with tongues.
Shade turned to Scooterloo. "And now what about you?" she stated. "Hey, that rhymed." Scootaloo shrugged. "I ship you with my next-door neighbour, Rumble."
Rumble flew in from the window because that loser and his lame brother hadn't been invited to the wedding and he and Scooterloo hugged and then she did a wheelie on her scooter because she was so happy. And she learnt to fly because she was so happy.
Shade turned to Buttonmash. "And lastly, a ship for you. You and Sweetiebell are perfect for each other."
Buttonmash shook his head. "But I really love Princess Diamond Tiara!"
"I'd thought of that," said Shade because she'd thought of that. She pulled out a little tiara that had been hiding in her mane and passed it to Sweetiebelle.
Sweetiebel gasped. "It's beautiful!"
Shade explained. "Now you can cosplay as Diamond Tiara and Buttonmash will love you."
"Yay!" shouted Buttonmash and Sweetybelle together. Sweetiebel leaned over and whispered into Buttonmash's ear: "Is it okay if sometimes you wear the tiara?" and Buttonmash smiled and nodded.
Shade looked around. "So is everything cleared up now?" There were murmurs from the crowd. "Okay, okay," Shade asked, "if there is anypony else that needs shipping, please form an orderly queue outside the venue after the wedding." She went to sit back down and the crowd started to be quiet and show a bit of respect for the princess who was having her wedding right now.
So the rest of the wedding went pretty much as planned, except that Princess Diamond Tiara looked even beautifuller than planned. (Well… not fuller…)
After Shade had finished shipping the rest of the guests, everybody had a big dance to celebrate their new ships and the happiest couple of them all, Princess Diamond Tiara and Baroness Silverspoon.
And the music was provided by DJ-PON3, and Octavia Melody and her band, and the Ponytones, and Sapphire Shores, and the marching band of the Royal Guards, and Lyra, and Sweetiebelle. And everyone liked it because it was good.
And then there was the honeymoon and they went to Griffonstone and spread the magic of friendship because Rainbow Dash and Pinkie Pie hadn't done it very well. And then they went to Yakyakistan and fixed the bad attitude of the yaks that were there. And then they went to that llama place that was in the other chapter and all the llamas loved them. And then they went to that deer place that was in the comics and something happened and then they went back home and lived happily ever after.
Until the next chapter, anyway.
Dun, dun, DUUUUUUNNNNN!
