In my line of work, that actually is a qualified disability and will get him accepted during intake with the state case manager who has to approve him for job search/job coaching services.
I've worked around people like Russell. Some much better than him, and some far worse. Russell 1,000% has (clap) a (clap) did (clap) a (clap) bility (clap). And NOT the Mobius.
He at the very least has LOW emotional maturity, poor problem solving skills, definitely VERY POOR hygiene (something that always gets noted in Cerner after weekly appointments), and he possibly shows some severe anger management problems on top of his Cluster B dumpster fire of a personality.
I see people like Russell Greer USUALLY inside a mental health satellite facility, in an office. That, or the DRS office. Because it 'taint real safe even to do an appointment with someone like him at the unemployment office since people like this are sometimes prone to "lose their cool" or loudly overshare and then we may be asked to leave.
Mental health facility is the best. Why? Well... Russell's doctor and therapist or group meet there. Even if they aren't there that day, we get access to the patient's medical records and can get instant assistance, either through the nurses, or the on site police officer that works there in case they make threats or get violent. This absolutely happens more than you think. But think about it: If they COULD get a job on their own, and keep it, well...they wouldn't need an agency that serves the disabled to help, would they?
Last I'll say on this.
JUST because Russell doesn't have a formal diagnosis that anyone from here, Reddit, or 4chan, can find, DOESN'T MEAN anything. But I am saying for myself, and what I see every day in the wild... Russell Greer has SEVERAL disabilities besides Mobius. I am sure that even if he never had one, the Vineland and/or Weschler was at LEAST talked about. Of course, it would've been up to the Greers to consent. A big problem lies with parents unwilling to accept that their child may have issues, so they refuse testing--even if it turned out to be wrong in the end.
