Have we discussed the pictures of Brian’s bedroom (after he went missing), some of the books he was reading, and some of his Pinterest posts? Wasn’t sure if I missed it. Thought some of our posters familiar with these types of books and posts could chime in.
I think this is likely a nothing burger. People read all kinds of books and it doesn't mean anything. Art is often dark and violent and full of meaning, but sometimes it's just art. Gabby also was reading a book about a serial killer during this trip. So, if you are going to project personality traits onto Brian based on the books he read, or the art he liked/drew, then you have to be willing to do the same for Gabby.
I am a voracious reader. I read about ALL kinds of things. I would hate for my book collection to somehow justify anything about how I conduct my life because I am nothing like the books I read in real life. They're just books.
A lot of people seem hung up on the fact that he liked to draw Hellboy (from the comics) and other violent cartoon characters. Well, didn't someone else draw them first?
It's a weird thing to fixate on. It's like saying that people who like the horror genre of movies are all psycho serial killers.
