I guess this gets at what is this medium? When we listen to the events, is KC providing the sound of what happened and where he cannot paint the picture with sound he overlays narration or is KC providing a soundscape from a master journal pieced together from multiple accounts?

I have been in the camp of hardcore journal. Someone observes, comprehends, remembers, records. This section has thrown me for a loop because of the importance and ambiguity of the soundscape. Datu seems to have survived the attack, buried his friends, recorded the events in his journal and then spoken to Michael about the events.

There does appear to be a cognitive component to the outbreak. Maybe the smarter a person is the harder the contagion has to work to rewrite neural pathways. Maybe Datu is stuck in the middle. I think it is critical to remember that Datu has two wounds. A scratch which I think of as a little one attack. The little one is surprisingly killed, because they do not have a gun truck I am sure they thought the humans would be easy pickings. I get the impression that the little one is killed and then Randy bites Datu.

if the little one was not killed, I do not think it would have let Randy bite Datu.
