I was surprised when the child asked helper questions instead of being scared by everything that had to do, even calling her miss but it has a lot to see that he is a child because he does not know much hate like adults. I imagine the relief they felt when they opened the hatch and did not see any robots nearby, but at the same time it was not a good idea to leave all in case the robots returned at least some men on the surface had to last a couple of hours to verify that all is well.
