Scootaloo wants to be just like Rainbow Dash, and barring that, to be like every other pony. She's ashamed of her true nature, the one she must hide from everypony or be hated and cast out, or worse. She doesn't know what she is, only that she can't eat the same way other ponies do, and she has to keep the terrible consequences when she feeds too much always hidden and never seen. But when a pony begins to truly care about her well-being, Scootaloo finds out that being loved makes it harder to keep a secret than when nopony cares about you at all.
