That sounds familiar to what happened to someone else I spoke to. Their friend just up and supposedly left for home even though they'd promised to go together. If people just up and left suddenly in the place you were in before, it doesn't sound like this place is that different, at least in that regard.

[She sighed at his last comment.]

From what I've gathered, a lot of people arrived here because they were feeling 'displaced'. Some were even about to die in the timeline they came from. I guess it's a matter of choosing what they prefer; finding a new home here, or going home where they don't feel they belong.
