I think the scariest aspect of this whole thing so far is that it's not just our one dome. I'm taking what I see at face value though, so I'm not going to believe everything our warden's are telling us... but we know for certain this dome's not like the last. But if there really are other prisons out there? It makes you think about who or what built these places. And their capabilities.
I'm all for another exploratory trip, but I have a feeling it isn't going to be easy. Wish we still had Senti with us, honestly.
