A part of him was sure it would be interesting to sit down and compare what was similar and what was different between all the different places the people he'd talked to so far claimed to come from. That part was quickly distracted by a strange moment of vertigo as he stepped through the doorway. He would have blamed it on his less than perfect health, if not for the fact that this also didn't seem like where they'd been meaning to go. It was an office of some kind, with no other exit he could see which would conceivably lead them towards the shed his roommate had mentioned.
"Edgar? I don't think we can get outside from here."
Maybe the other man had simply gotten disorientated in the halls. He could see how that might happen.
