Either that or unusually and specifically replicated well. That's what I was trying to figure out. I can't doubt that anyone on the ship has bad taste in humor to pretend to be dead people, but I at least ruled out we weren't communicating with an alternate universe of themselves, since Dahut knew Luke. There were messages that seemed like it came from Viktor and Scien. I'm assuming Arthur and Charles have been on it too, since I see their initials.
