On the theory of Lizzy having Todds child, it is possible. That would mean if she got pregnant right before the event, she would be around 6 months along. If it is Sauls it would be 4 to 5 months along. If Lizzy is as big as Pete said she is, the there is a chance it is not Sauls at all. I really doubt that, but who knows, Kc has his ways to mess with us.
