So i've been following Christory through the wiki for a few years now, the most recent thing i remember reading was the Doopie episode so it's been a while. Deciding to come back, i spent quite literally the entirety of Saturday on the wiki, seeing what's been happening and reminsicing on what i already knew.
Something notable that happened between Doopie and now was the Idea Guy saga. Now i might have this incorrect because i felt the wiki kind of glossed over the inception of the IG's so correct me if i'm wrong; the IG's had Chris following their commands because they were wreaking havoc on Chris' alternate-dimension-where-all-his-characters-live, from getting visions from Magi-chan to torturing Rosechus and threatening to nuke the whole "place?"
Now it's been known for a long time that Chris believes that his characters are alive and would suffer from any misfortune inflicted to them in the canon (which is why they never have any), and despite the wiki quoting similarities in episodes of Family Guy or South Park, i personally believe this is something he could and might have come up on his own. This, i feel, is pretty innocent by it's own.
But if he can be extorted and blackmailed simply by pretending to hold his imaginary world hostage, then I think he's far more mentally unstable than we've assumed even this far (and further adds to my confusement of how the wiki hasn't properly detailed the IG's rise to control, though maybe i'm just slow-in-the-mind)
So going back to the question on the title; what is the state of Chris' mental stability? Can we assume it's downgraded, if not straight plummeted into developing further psychoses/disorders? Not going to name any cuz i'll get them wrong, but honestly I think that sort of behavior goes further than any level of autism can even hope to explain.
