I am definitely very interested in these ideas. Especially with the thought of Marni still being alive and all.
Okay, so what about this idea..
Rotti's doctors save her. Give her new blood - new organs. But when she comes to, he holds her as his captive.
But she manages to break free - and this could be where the storyline begins. Maybe Rotti calls up Nathan and tells him to go after this woman and reclaim her parts. So he goes after her, stalks her down, and of course at the very last moment realizes who it actually is.
Whadya think? Thoughts? Other ideas to throw in there?
