Scootaloo feels like nopony takes her seriously because she can't fly. While other pegasus fillies her age can already fly, at least at low altitudes and short distances, she can barely get herself off the ground for more than a few seconds; and that's while flapping her tiny wings at full speed.

At the end of her wits, poor Scoot is starting to convince herself that she'll never be able to fly. Not knowing what else she can do, she runs away from home, on the hunt for somepony, anypony who can do the impossible: teach her how to fly.
