Hurm. This one is intriguing me. The only problem is that I don't know much about Cassandra. Her mother's Lady Shiva right? And when she was 8 she killed someone, and then lived on the streets until the Batclan found her. Was that during No Man's Land? I've haven't read that yet. How old was she then? I may have to change cannon a bit... *ponders*

I don't know if I'll ever write it, but I'm certainly thinking about it! :)
