...most of those five were, anyway. The blue one - I'll get to him in a minute.

We call them infiltrators, and yeah, that's about it. They think they've always lived here, everyone around them remembers them living here. They'll remember themselves once we finish up the investigation. Some of them are usually at the middle of whatever the investigation is, though, so they're usually good leads to figure out what we need to be doing.

The guy in blue - he's not one of us, but he's familiar. We've seen him in other worlds before, but never in Liminal Space. Don't ask me what it means, because we're not sure either. All we've got is wild guesses.
