Perhaps it's just with strangers... Or it could have been her position at the time. She'd only just arrived here and the friends she was waiting for hadn't picked her up yet. That would make anyone a bit nervous.

[Well, it could be any number of reasons and speculation is kind of useless. Moving on to the more important topic.]

I thought that might be the case. Well, as you probably have realized by now, people can be plucked out of their own world at any time, no matter what they were doing before. The same goes for being sent back. The difference is you don't keep your memories of this place when you go back to your own world.

But people who have left can return, and sometimes they have their memories again when they do. Sometimes, however, they don't.
