<powerlevel> Not a mental health professional, but I am courtroom staff and have clerked Aid & Assist hearings. The following is based only on my experience and reading the documents involved in these cases.</powerlevel>
Primarily what happens in the course of treatment in a state hospital for defendants is that they are required to attend legal education classes. This may or may not be a benefit to them initially, but usually once the Rx is sorted out and they become more responsive, they become well enough to clear that very low bar. Examples of the questions they must be able to answer (recorded in the psych reports) are:
- What are you charged with?
- Do you know the difference between a felony and a misdemeanor? Which is worse?
- How should you behave in the courtroom?
- What does your defense attorney do? Do you get along with them all right?
- If you need to ask your defense attorney a question during court, what should you do?
- What does the judge in the courtroom do?
- What does the prosecutor in the courtroom do?
Things like that. Chris could learn the 'correct' answers and memorize them in time, because they really don't touch upon his fantasy. If he isn't persistent about his craziness during this particular part of the evaluation, he can probably be determined to 'aid and assist' in his defense. However, since he is wholly immersed in his fantasies, he tends to perservere and may spend the rest of the evaluation meeting blabbering nonsense. But, he could learn these answers. A lot of it may well be news to him. In spite of his previous encounters, I wonder how much of this process he understands even on a basic level.
In the report of the evaluation meeting, there is sometimes a diagnosis, and the doctor can have an unofficial opinion whether he is fit to proceed. All of the other documentation of his behaviour is also taken into consideration, as well as whether or not there has been any progress (usually evaluated shortly after admission, in 90 days, and again nearing 180 days).
If he is deemed fit to stand trial at the end of the treatment, they will be back in court. Mr. Heilberg is smart to time this to conclude (probably) with the end of what would be the usual time served. It is very likely that the timeline of his transfer has more to do with availability of a locked mental health bed than anything else.
Meanwhile, the staff/his attorney/their staff/social workers etc., have probably been looking for a secured facility for him. It will be likely he will be considered a sex offender even if he does not have to register (I do not know what that criteria includes or doesn't), so this will basically be a fairly secure home for adult male retards. Where that ends up being is going to be entirely dependent on what is available.
tl:dr Maybe, but I'll bet the rent he's in a state hospital.
