A video message appeared at a random time only showing now. Meaning it needed to meet a set of conditions to be displayed. If Logan met all of these conditions, it would appear in front of him like it did now. His parents had probably programmed something like this into Ash.
The first condition would be for Logan to be in one of the Green households where Ash is able to be operated. The second condition, for Logan to be eighteen years of age, and finally the third one, for his parents to be confirmed dead.
"Logan we want to let you know, if we have left this world, we did so trying to save it." His father said. "It was a choice that we made. This is part one of the video, if you are seeing this now, then in one of our households, please head to the simulation room. There we will explain everything."
"Logan, we love you." His mother said before sniffling again, and the video call ending.
