He was a simple stallion of honest stock, and she was content with that. He would write no great sonnets, sing no great ballads, think no great thoughts -- and that was okay. It was the little things, the things he could do, that made her love him. His sweet smile, his dopey accent (how does a nice Canterlot boy like that pick up a Calneighfornia drawl?), his cooking, that ridiculous love of hoofball -- the things that made him real.
Let the neighsayers come. Let them call her sham, pretender, whore. She didn’t care. She had what she wanted.
Rarity and Sweetie belle's parents
Oooh this is a tough one
WAIT! The parents of Rarity and Sweetie Belle! He has a bad Californian accent...kinda?
shining armor and cadence
Initial impulse is Hondo Flanks - Cookie Crumbles, except they speak with Minnesota accents. California accent suggests Shining Armor, except I wouldn't think him 'a simple stallion of honest stock' given he is Captain of the Guard. Except, well, 'sham/pretender' suggests a Royal Pony - which leaves the Alicorn Tetrarchy. And when you factor that in? Twilight - Flash Sentry, and if not that Shining-Cadance, but FlashLight is the more likely here.
I think this is Cadence & Shining Armor.
My eyebrow raised for a moment at the word 'whore,' and why that might be relevant, but then I remembered that Cadence is the only alicorn who's married, or in fact shown any romantic interest in anypony.
