Mostly I think we all assumed the missing people were on the second ship that didn't make it through. Cuz there were two big ones to start with-- and a whole mess of little ones. Or else got stuck in the portal place-- liminal space. Plus a lot of us were hallucinating, not just my kind, so could be some people figured we imagined this person or that person.

There was a lot of shit going down, most of which could pretty easily explain missing passengers.
