Do you accept episode ideas? If you do here is one.
The girls are able to get outside, doesn't have to be at night, you can figure something out if you want it to be in the day. But the point is they leave the pizzeria for a couple hours and see the outside for the first time since the incident, and they have like a disguise. I mean, other than the look and the metal that showing, they look pretty similar to a human. Could work. This is just a suggestion.
