The groups really backed into a corner this chapter I think they will get through this but with how cunning the mother is it might not be Norman's day tomorrow but another of the kids. Right now there only position is figure out a way to have the shipment postponed without demons figuring out about the escape. I think there only move now is they all escape at once and try and come back for the kids later. Mama will be forced to make an excuse if she wants to survive. And this gives them more time but someone irregardless will get sacrificed in there place tomorrow.
