It has occurred to me that, of Daniel's girls, with the exception of Pip, we still have learned next to nothing about Specca's life before Ashwood. We know of Alyssa's and Star's mothers, we've heard references of Falla's and Luna's mother, and we've SEEN the other girls' mothers and heard what their lives were like before they met Daniel. But Specca . . . her past is still a mystery.
All we really know about her is that she was fascinated by humans and their way of life and left to become part of it.
Why do you think that is? Is there something she's trying to escape from? SomeONE she doesn't want to think about?
