“Right you are, Princess,” cackled Chrysalis gleefully, nearly prancing back and forth in front of the gathered wedding guests. “And as Queen of the Changelings, it is up to me to find food for my subjects. Equestria has more love than–”
“Oh. My. GOD. Would you shut UP?” interrupted Cadance, rolling her eyes. “It's bad enough you tried to steal my fiancé, what's-his-name. I can understand that, he's pretty cute when he keeps his mouth shut. But are you TRYING to RUIN my wedding?
“I mean, just look at those bridesmaids. I wanted MATCHING dresses, not this mishmash of clashing fashion disasters. And magenta for the hall decorations? Really? Did we go back in time five years? I had a modern wedding planned before you ponynapped me, not one from the time of caveponies!
“That's not even mentioning the wedding guests, either! What did you do to my invitations? I only had unicorns on my list! The pegasi are bad enough, but you invited mudponies too? I'm just glad we decided not to have this wedding at my palace, because I would not want to be responsible for cleaning up all the dirt they've probably dragged in here. Well, I mean, I wouldn't want my servants to be responsible, which is pretty much the same.
“And another thing–”
The guests watched in awe and disbelief as Cadance continued to rant, expressing her disapproval with everything about how her wedding had been changed in her absence, up to and including Princess Celestia wearing her usual 'ugly and ancient' regalia rather than the dress Cadance had picked out.
Standing side-by-side, Shining Armor and Chrysalis listened with open mouths as a seemingly never-ending torrent of petty disappointments and whining came from Cadance. Almost as one, they turned to look at each other.
Chrysalis inclined her head, nodding towards Cadance, then raised an inquisitive eyebrow at Shining Armor.
“Dearly beloved,” announced Celestia, smiling proudly, “We are here today to join in holy matrimony Shining Armor and Queen Chrysalis...”
Frowning slightly, Twilight watched the ceremony from off to one side of the crowd of ponies and changelings. Her seat was unstable, consisting of the tied up and very thoroughly gagged Princess Cadance, but she was able to keep her balance without much trouble.
“Well, I guess it's the lesser of two evils,” she sighed, ignoring the struggles and muffled protestations of her perch.
Princess Celestia concluded her speech, and Shining Armor carefully maneuvered the ring down the jagged and twisting horn of his new wife. They kissed, and for some reason the changeling Queen was suddenly blushing.
They do kind of make a cute couple, though, Twilight thought, a small smile making its way onto her face despite herself.
