So, do we know if he HAS been sent to a psych lock-up? Maybe that's what happened, but I think it's just as likely/more likely, that they just finally bounced him into the prison system, because of the 6 month continuance.
Jails aren't intended to house people long-term; That's what prisons are for. Jails are SUPPOSED to house you for a few weeks/months, til they can get you into court for sentencing, then off to prison. That said, the system is a mess, and it's not uncommon for people to be held in jail for a year or more. But in general, they'll find a reason to send you into prison if they can, to free up the jail cell- And getting notification of a long continuance is exactly the kind of excuse they'll typically use to do that.
Then again, with Chris it hardly even seems to matter- Most people would be bouncing off the walls in protected custody, never speaking to anyone else, and barely any time out of their cell. But Chris seems fine with sitting by himself, having imaginary cartoon adventures in CWCville. So even if he did get sent to psych lock-up (which would be worst-case scenario, for a normal inmate), I doubt that Chris would even care (except maybe being offended by the implication that his hedgehog-CPU-princess status isn't super-duper-real, and requires psych treatment)
