Well more like dark secrets then facts but whatever 1. Jack does in fact have schizophrenia. that is mostly the reason behind his weird behavior around most people he is not familiar with, he does sometimes have hallucinations which does cause him some problems. and his condition also causes him to not really feel emotions like a regular person. and he isn't comfortable with talking to people about his mental state because he feels as if the voices in his head will kill him if he does 2. Felix is unable to tell a lie and cannot really be trusted with secrets for very long because he cannot tolerate the guilt of hiding things from others 3. Ray has severe abandonment issues and will often be very clingy to a person he is close with to the point it can start to become annoying 4. danny is very territorial and possessive and tends to get very aggressive to a stranger if they come off on the wrong hook
