Reid seemed content to just let the Cajun man babble at him, that and the charming smile was pretty hypnotizing. He has charisma, that was for sure, and Reid often felt awkward around those who did. His mind was beginning to wake up now, sharp and alert as usual, and he was beginning to piece the tidbits of information together and formulate a mental image of the place he had been... brought. He wasn't about to use the 't' word like the younger man had done.
He was going to imagine for a moment that this was a normal case, and that their captors were most definitely normal human beings, and see what he could draw from this, whether he was deduct anything useful. If what the men were saying was true, then the team wouldn't be arriving within a few hours with their guns and vests and smoke bombs and SWAT units. At least if they... if they were being tortured here, if people were in fact being subjected to cruel experiments, he could perhaps use what he figured out to keep himself sane. And alive.
So, they were being kept in a 'glass prison' or a 'vessel of imprisonment', according to the literal translation of the name of the place. Their captors were probably narcisistic, cruel, and most likely atheist, if they were attempting to play God like this. Atheist, or with a strong hatred of religion, most likely linked to childhood trauma or abuse surrounding the subject. They were probably controlling, possibly even OCD. And they were sadistic, if what the Cajun was saying about torture was true.
As for the sun not setting and the 'other worlds' thing, well. Reid hadn't gotten that far yet. Let him deal with the fact he was in a place filled with people who were teased, tortured, and eventually killed and left to be found by their fellow captives. That was enough for now.
He was now stood toward the back of the group, going through the survival kit and only partially paying attention to what was being said.
