'Gain more of an understanding of this place'? By just standing around in the darkness like this? How could she even...what? Byrne didn't understand at all, and Rei's lack of concern, plus her calm, almost tired look there, made him worry even more. Was there something she wasn't telling him? Or did she just really not care about her own safety?

"Rei." His look became more serious. "I don't want to barge in on whatever other plans you have, but I'm not comfortable leaving you here in a place like this to just--just stand around in the dark by yourself." Where you could possibly be eaten by something, y'know? "It's too dangerous." Which was an obvious fact, yes, but he felt the need to repeat it.
