Rainbow Dash had exactly what she wanted, and all it took was one freak accident to take it away. In an instant, her life was changed and she lost everything she had worked for.
Now a half year has passed. Life is simply something that she goes through now, instead of something that she eagerly looks forward to each day. And her friend, Applejack, has been bothering her about some sort of surprise for a while now.
Rainbow Dash hates surprises.
