After seeing Spike get rejected by Rarity, Meadow Flower follows him in an effort to cheer him up. Her cutie mark is a sunflower after all and her special talent is making ponies feel happy and sunny. She only came to Ponyville to visit her fellow Wonderbolt trainees, she didn't think she'd end up falling for the dragon.
