Go back further. Wilken and Gerth had been sent here in place of the contracted GI security to stop/kill the assessment team. So why hadn’t they acted as soon as they arrived on the transit station? With so few people there, it wouldn’t have been difficult. They would have needed an exit scenario if they had acted on the station, but they needed an exit scenario even more here on the facility. The team’s shuttle wasn’t wormhole capable. They would have to return to the transit station, kill the PA staff who would possibly be asking a lot of questions about what had happened to the rest of the assessment team, and steal a wormhole capable ship. (Preferably a ship without a bot pilot who would vigorously resist being stolen.) That sounded like a lot of work, especially considering the fact that there were combat bots on the facility, ready to destroy intruders, so why had GrayCris hired someone else?
