"It is no accident that the photographer becomes a photographer than a lion tamer becomes a lion tamer - Dorothea Lange"
The chapter opens with the questions, Why Navidson, and why not someone else. Which is a common question to ask when faced with a traumatic event, why this person, why not someone else. It is true that it seems random that it just so happens that Navidson, who had happened to start documenting what was going on in the house without a hint of realization of what was truly going on. Even Navidson proclaims "How the fuck did I end up here", only to find no response at all.
It is postulated that the creation of the house is due to Navidson's own psyche, after all, he had a troubled youth with a drunken father who passed away, and a mother who did not care for him or his twin brother, who simply disappeared. However, this is contested as many people have lived in the house, around 1 person every three years, since the 1700s, and it is stipulated that they did not stay very long due to the house's properties.
It is also noted that Navidson likely pursued photography as it captured moments that were so fleeting.
So why Navidson? The answer is quite simple: someone like Navidson would have come by eventually, it was inevitable. Why not someone else? Because only Navidson would be able to delve so deep, and be able to bring that vision back.
The house chose Navidson just as much as Navidson chose it.
Truant opens up his part of the chapter in the footnotes talking about Lude, how their song and dance is likely what made them friends. While Lude was popular and knew everything there was to know about the place he lived, stated to be L.A. here, Truant was more able to captivate people with the stories he spun.
However, it moves on to talk about the trunk filled with the chapters for the analysis of "The Navidson Record". How Truant finds a sort of kinship with those things, discarded, unwanted. Much like how his father died suddenly at a young age, as well as his mother shortly afterwards. It was declared bluntly by a counselor for disaffected youth, "You like that crap because it reminds you of you."
It leaves Truant wondering a similar question though, Why him? Why not someone else?
He ends by stating that his curiosity and connection to the discarded objects is the simple answer, and both we and him know it.
