Hi everyone, first time poster, long time lurker.
I knew from the start that prison wouldn't be good for Chris. A lot of people have said that taking him away from his videogames and funko pops and other crap might bootstrap him, but that stuff was actually keeping him relatively stable. Remember that he's an autistic manbaby retard and he uses this stuff for comfort and familiarity. Him saying "I need my stuff to feel safe" in court was completely serious. It's probably why he blew all of his stolen money on toys as well when he was banned from returning to his house.
Without his consumerist garbage, he can't construct his sonichu delusions because he is so stupid and uncreative that he can't imagine these things without having physical images for him to focus on and base his fantasies off of (this is my guess why he always carries his sonichu medallion, it gives him a focus point to retreat into fantasy). So now he's fixating on what he does have, which is probably the Bible and chapel sessions. Yet instead of taking away any sort of lessons from the Bible, he does what he always does with other peoples' narratives and wraps it around himself and alters it to his liking. He also always needs to be the center of attention, with his stupid gal pals and enablers, and now that he's not getting any of that, he's concocting increasingly grandiose delusions because he needs the validation. He's like a sponge who just absorbs whatever is nearby and imitates it (poorly), and I have no idea just what the hell he's going to turn into if he's left alone with criminals or lunatics without being on zombifying medication.
