Fluttershy gets stuck inside for the duration of a bad thunderstorm passing over Equestria. Stuck in the cottage with Angel hiding from the thunder and all her furry friends safe and warm in their own burrows, her plans for a wonderful picnic have been ruined. Yet there is one person left around who was supposed to go on the outing with her, though she isn't sure how much use her brother Zephyr Breeze is going to be after having lost his job at the salon recently. Still, she did live with him, so it had felt wrong not to ask.

As the day goes on and things take a turn, Shy begins to realize a lot of things about herself. A prank meant only to help smooth things between them turns into a mistake that could divide the siblings forever, or maybe even... bring them closer?
