Rainbow Dash is many things. Awesome, radical, amazing, and at least twenty percent cooler than any other pony in Equestria.

She is also lost, lonely and uncertain. Not that anypony else would know.

During the day she is everything everypony expects her to be: she is fast, daring, and adventurous, but when the sun goes down, she is left alone with her thoughts. Tired of simply yearning for something more, she sets out on a night of soul searching and stumbles onto a friend in need, and maybe, underneath the vanilla twilight, she finds something more.
