You're probably wondering, "why, of all ponies, would I pair Limestone with her"



Cuz she's cute, I don't need any other explanations.



I just happened to spot Sprout on the background of a screenshot (I think it's from the episode Viva Las Pegasus) and I frigging fell in love. sHE IS PeRFeCTION



And I just happened to pair her up with Limestone because I was thinking about it at the moment, I might retcon this sometime in the future but who knows? Lemme enjoy it now~



Btw, Sprout seems to be portayed as a lively, cheerful and perhaps goofy mare by the way I saw her act, I actually made up her personality to fit my story better



Now let's get back to their backstory~



After everything that's happened in the Pie family; Pinkie moving out with Cheese (who her father kinda didn't appreciate much since he didn't quite have the "pie family profile", but pinkie doesn't have either so whatever), Maud moving out and having multiple children with different fathers (and never even marrying one of them), Marble marrying a mare (which her father completely disapproved), Limestone felt a bit... Frustrated to stay in the farm. Due to her parent's, specifically her father's, super strict beliefs and traditions, Limestone had always believed it was her duty to take care of the farm. To follow "the rules", and wait there to be eventually chosen to marry some stallion by the "pairing stone". Taking care of the farm was her destiny, she was meant to do that. "Cuz it's what her cutie mark was telling her", she thought.



But as she saw all of her sisters living their lives all freely, weirdly, and happily, she felt like she could somehow be missing something in life. She had that feeling sometimes but always went back to her conservative thoughts. Haven't worked much on how they meet yet.



One day, the rock farm happens to be having problem with weird, unknown, big and strong weeds growing everywhere. They wouldn't stop growing even if you cut them or pulled them away, so some other pony from a nearby farm recommended Sprout's help. Limestone was rather incredulous and confused when a pretty "prissy" and soft looking mare showed up. She? Of all ponies, could handle those monstrous weeds growing everywhere that not even Limestone could get rid of?"
