After querying the onboard AI computer Melanie finds out that the others was a systemic event and earth has been taken over by them. Nothing remains. Yet a distress signal opportunity did lie ahead for Melanie and Rando. She also figures out that Rando was indeed mind melded with them, leading to the conclusion that, this connection between them was the reason for her success. So she keeps that in mind. This was a long way if they had to survive, so she let Rando loose in the station free to roam about, sometimes even without radio. Although Rando was clearly on the other side, Melanie still allowed him to talk to the computer if that what wished. She kept on working her way out on her own, checking with the computer about his progress and health.
Their could still be some earth forces who must have survived during the take over. So she started programming the computer for locating a safe rescue party if any.
