Does she have a secret life? One even she doesn't know about?
Ever since seventeen-year old River can remember, she's always had the real sense that she is in the wrong place. Because of this, she battles a constant restlessness that consumes her. Running is the only thing that helps.
Another reason she knows she's wrong?
She can see the light around a person. Everyone gives off energy and somehow, River can see a bit of it. She knows when someone's good or bad. She just doesn't know what a blurry light means, like the light around the creepy new kid, Wicked.
