What makes it egregious is just how important Kiden is. Kiden saved her life in NYX. Maybe not literally, but certainly by helping her break free from Zebra Daddy’s control. Otherwise she could very likely still be an empty husk of a person quietly enduring all manner of abuse while peddling her body on street corners. And considering who Laura was at the time, and how broken and beaten she was, it’s unlikely she would have ever gained the sense of self necessary to do it on her own.
That’s a BIG deal, and for it never to be touched on is a major failure by the writers.
