"What statistics?" They didn't really talk about those back in the day. Just words of wisdom passed down from the previous generation that taught them how to do some basic tracking and told them to stay put if they ever got lost out in the woods, that kind of thing.

"We can go take a look, if it would put your mind at ease, but. I do not think there's a door." Doc might have a kind of persistence and resilience that has seen him live this long, but. He also has a kind of learnt helplessness after being trapped underground for so long. He had spent weeks, maybe even months, combing around for an escape route. He even tried starting to dig upwards to climb a way out with just his knife and his bare hands.

"Would be nice if they'd built a natural sort of way out. Maybe it's in one of the routes we haven't explored yet." They might get lost but. Honestly Doc is worried about Raylan losing his shit at a dead end. This place doesn't exactly exude calming energy.
