I haven't seen the front door myself, but our trigger-happy Overseer was talking about authorizing surface expeditions -- so there has to be some way out.

So, item one: supplies. We need to know what we've got and what kind of shape it's in. Let's go over ideas about how to do that once everyone's here, okay? I'll bet there's a lot neither you nor I know about what's out there.

Item two, getting this place livable. Cleaning, opening up the doors that are stuck, figuring out how to dump and clean the toxic waste, that kind of thing. [He waves a hand.]

Item three, access and information. Sharing what we've all figured out and working on a plan for getting the front door open.
