What do these images and events have to do with Jim’s manhood? How do Jim’s feelings about his masculinity seem to shift throughout the story and why?

There are several moments in the story that seem to allude to the question of Jim’s manhood. On p. 55, he faints while stepping over the corpse of a security guard. On p. 57, we find out that Jim doesn’t know how to drive and that he has to be driven through the city by Julia as they search for survivors. In response to Julia’s question “What can we do?”, on p. 57, we read “It was [Jim’s] turn to take the lead” when he comes up with the idea to use the telephone, telegraph, and rocket flares to try to contact survivors. On p. 59, we are told Jim “seized the wheel” and Julia “forgot to wonder at the quickness with which he had learned to drive her car. It seemed natural.” On p. 60, we read “The shackles seemed to rattle and fall from [Jim’s] soul,” and he begins to embody the “lone majesty of kings long dead.” Finally, when Julia’s husband and father send up a rocket flare to the rooftop where she and Jim have taken refuge, Jim falls to his knees as he is momentarily blinded by the light from the rocket.
