Super Stallion
(Note for new readers: I started work on this fan fic before Mysterious Mare Do Well aired)
Rarity had decided to take a balloon ride out to the cliff where she found a rock with filled with gems she found when she was just a little filly to do some reminiscing after she felt down not long ago. Rainbow Dash helped pull the balloon because it was so far from Ponyville. As they approached the cliff, Rainbow Dash slowed down and Rairity pulled the cord allowing decent. Rarity could see the halves of the rock that cracked open years ago. Her eyes gleamed in happiness and nostalgia.
"Seriously?" said Rainbow Dash. "You came out here just to look at rocks? I thought that curse from Discord was uplifted!"
"I said we'd never speak about that!" Rarity snapped. "And these aren't just any rocks! These halves of rock once had gems in them which I found when I was a little filly. Partially thanks to you, might I remind you."
"Whatever. Take your time. I'm gonna practice for my next race."
And Rainbow Dash sped off before Rarity could say "Really." Rarity looked at the rock, but the sun was so bright that she squinted.
"Goodness! This is much too bright," she complained to nopony in particular. So walked to the other side of the rock.
"Much better," she sighed. "Seeing this reminds me why I stuck to being a fashion designer. I've even forgotten why I was so worked up earlier today. Twilight was right! A little nostalgia can brighten up your day."
She leaned her head back in relaxation. But as she did so, she lost her balance and fell off the cliff. She screamed so loud you could almost hear her from Ponyville. Suddenly, somepony rushed to her rescue, carrying her in their front legs. But it wasn't Rainbow Dash. It wasn't even a Pegasus! It was a stallion with a yellow coat and a red mane, tail and cape, but no wings!
"But how?" Rarity questioned. On his flank, she noticed his cutie mark was two red "S"s.
