To love someone

Claire just wanted to interview the strangely quiet girl who drove into town in a dented Ford.
It was obvious she was a run away. Many had come to the town to find shelter from troubled pasts. If her dingy jeans and downcast eyes didn't give her up as one, then her vacant stare did. Strangely, she seems to know Claire. She knows a Claire who can't exist, beause she's always lived in the town. Claire couldn't be this other person, could she?
And if she is, does that make her a monster?
