Again, have you ever seen, conversed with or listened to a conversation with a psychotic person? Psychosis does not look like this or act like this... yeah people can argue not all people with mental illness present the same & there are various degrees but I don't care who you are- psychotic is psychotic!
Psychotic people don't act this way. I just don't get how people can even entertain the thought that Casey is insane.
She has no problems with her speech patterns, she seems perfectly able to put sentences together, her thought process seems organized. She sure doesn't seem to be withdrawn, isolated or unsociable. Her cognition appears in tact, as does her personal hygiene. She seems to have plenty of energy and drive, doesn't look like she lost interest in things she enjoys. She is plenty motivated and has follow through when it's things she wants to do.
In her interviews with police she doesn't speak of the goverment trying to kill her or plant things in her brain to listen to her thoughts, she doesn't claim to be Jesus or anything else even close to being a delusion, hallucination or being paranoid or being out of touch with reality.
