"Oh, that's just my outer shell, I told you before, right?"
"Don't tell me she also forgets things easily!" William got the feeling that she was asking herself if she said it or not, a thing that made him think in his mind about her mental status.
"Don't worry about your safety, my body is safe."
"..."
William refrained from asking anything, to not get a weird answer again. He kept walking for hours, following the stream of white fog around. He didn't see anything different, not until he ended up at a place where he could see beyond fifty metres.
The white fog seemed to recede from this place, showing something that was no better described as an opening. He knew her words from earlier had something to do with the real thing, but he didn't think she really meant it.
"Couldn't she have said a portal or a gate, other than opening," he thought to himself, feeling like he was dealing with a six years old kid or something.
