Fluttershy and Rainbow Dash are caught in a powerful storm near the Everfree Forest. They run to take cover in Fluttershy's cottage, but, during the trip, a large branch nearly kills Fluttershy. Rainbow Dash, despite being badly injured herself, takes it upon herself to get Fluttershy to safety and care for her until the storm passes.
