It's possible that he's batting below average IQ wise but still above 70 which is the threshold for legit exceptional individualism. He has a very hard expressing himself via writing, and I chalked it up to bad dyslexia. Jimmy is most likely in sped-in-all-but-name territory himself, as child molesters tend to have lower IQs than normal people. Mike might be a borderline case, but it's also possibly he has something else interfering with his cognitive abilities. He might have a severe untreated mental illness (if the walls are bleeding, it's hard to think straight), he might have a serious drug abuse issue. He could just be not very bright, but I'd have to see his test results to know for sure, and that's not happening ever.In all honesty I don't think he's quite... all there? We've interacted a few times and he never quite seemed like he fully comprehended what was going on. I'm sure he's incredibly easy to manipulate.
