Suddenly Sisters: The Trilogy

It was finally the day of the double wedding. Spike was waiting at the altar already with Diamond Tiara escorted to the Altar ahead of Apple Bloom. Sweetie Belle was then escorted by her sister Rarity and Apple Bloom was escorted by Applejack. Twilight began.

"Mares and Staillions, fillies and colts; we are all gathered here today for the first double wedding in Equestrian History." Twilight said. "So let's all make it a good one." She said. In attendance for this grand double wedding was all of Ponyville, the relatives of Diamond Tiara, the entire apple family clan, Twilight and Starlight's parents (both biological and adoptive in the later's case even if it's just her adoptive father); plus Shining Armor and his wife, the royal sisters, Tempest Shadow, Moondancer, Flash Sentry, the CMC, the Wonderbolts, Starlight's friends Trixie and Maud Pie; additionally the other elements of harmony, and last but not least Sunset Shimmer who was streaming the wedding for her friends from the other world to see (she was allowed to attend such a big event for that exact purpose). Cameras were also stationed to capture the weddings for all to see across the news.

"I turn my attention first to Spike and Sweetie Belle. Do you, Spike the Dragon, take Sweetie Belle to be your wife for as long as you both shall live?" Twilight asked.

"I do..." Spike said.

"And Sweetie Belle, do you take Spike the Dragon to be your husband for as long as you both shall live?" Twilight asked.

"I do; one thousand times over!" Sweetie Belle said. Everyone chuckled.

"Now for the other couple. You own vows, as you requested." Twilight said.

"Diamond Tiara...standing here now with you, under the tree that my ma and pa planted...I would like to solidify our own union so that one day our love too may grow as big as this tree has." Apple Bloom said.

"Apple Bloom...I was such a complete jerk to you when we were younger, and yet we both moved past it and found love in one another anyways. No amount of money could ever hope to replace the love for you in my heart." Diamond Tiara said.

"Bring forth the rings." Twilight said. Silver Spoon obliged. Sweetie Belle levitated hers to her horn, Spike put his on a claw, and the two earth ponies put theirs on a hoof.

"As the Princess of Friendship, I now pronounce you four, as the first dual couples to be wed in equestria during the same cermony!" Twilight said.

The Wonderbolts soon did a grand performance before the reception was kicked off. The two new couples then went on their honeymoons.
