Cobes isn't going to a group home. The older he gets the harder it is to find space in services like that, and Cobra is 32 going on 57. Clint has no intention of actually fighting him about it either. He'll spend money to keep boggy from wandering about toothless and homeless, but he doesn't wanna waste any more time. Getting Cobes to not run away or lock himself inside the hovel would take ages.
He's going to drink in his dead dog chair until he dies at 39 from drowning in vomit. Clint will do his performative weep about how utterly uncontrollable and unique Josh was, and live out the rest of his days with his slightly less embarrassing family.
The only way we'll get anything close to a group home is a court-mandated halfway house, after he breaks the law and only if Clint can't make the charges go way.
