After some replays, my interpretation is that the "Johann" and "self-esteem" outcomes are canonical, and the rest weird delusions or rationalizations brought on by trauma. ("child soldier" I'm not sure on. Could be some of both!) I think the figure who appears at the end--and who keeps saying "please, come home"--is Johann, his head bandaged and jaw wired from Laynie lashing out at him in her flight.
