Now that Nadia has found Katherine and that Katherine is no longer of use to Silas, I wonder what will happen to these two.
I mean, it seems that Nadia doesn't really care about The Travellers and Silas, and only used them to find her mother. Also, Katherine won't bother Silas anymore I think because he is not a threat to her and her primary goal is to survive. So I wonder, what could possibly be a threat to them? What keeps these two from living a normal life and building a normal mother-daughter relationship now?
