I don't think he needs a wrangler a la what null tried with Chris. I think he needs a wrangler from the state that has a professional distance from Cobes, untainted from Josh' online presence, to help him on a day to day basis if not simply a twice-a-week visit.
Clint or his mom can't do it, the parental connection will not be helpful. In fact, I think Clint should attempt as much as possible to take a step away from Josh and let the state wrangler do their job.
I don't know if it functions like this in America, but where I'm from you can get assistance from a local government assigned worker who is educated in how to help people with mental illnesses like anxiety reintegrate with society - they can help with whatever a given person needs, like grocery shopping, cooking or even going to social gatherings in a safe environment, so as to not regress further into an asocial shell of a person that cannot take care of themselves outside of the bare minimum.
Ideally, Cobra would get help with managing his finances, his hygiene, doing his laundry etc. and even seeking out social circles that aren't his usual druggy, stealy, rapey crowds.
I know, I'm dreaming big. But I would genuinely love to see Cobes flourish and grow as a person(

). I much prefer his tard Wendy's arc where he fucked up the teas over his current downwards spiral of huffing duster and slowly killing his bearded dragon.
