They are more concerned about some lizard dying than their family member who is on death's door. Have they ever tried an 'intervention' with him? Or they just content seeing him once or twice a year, looking 10 years older and like shit?
Yeah they did, or at least Clint did. It was on his birthday, I think last year, Cobes turned up to his own birthday meal with his dad massively late and shitfaced drunk, so Clint cancelled on the spot and gave Cobes a piece of his mind. How well did it go? Well for Christmas, Cobes turned up even shitfaced-er and became so belligerent Clint called the cops on his son and he ended up sobering up in the cells. No doubt they had more words after that. Clint tried twice and it had no effect. At this stage I don't blame him for giving up. He has his own life and his other children to be a father to.
Interventions don't work on people like Cobes. He has this autism-fuelled complex that anyone giving him advice is talking down to him or trying to take his independence from him. He resents advice so much he will do the opposite of anything he is advised to do on principle, just to show 'em. Interventions only work on people you have a chance of getting through to, people who have adult levels of emotional maturity and intellectual ability - they need to be able to have the smarts to understand the harm they are doing to others, and the maturity to care about it. Not only does Cobes have the usual problems of overcoming addiction, he has this idiotic defiant streak because he's a literal retard who is stuck at the 14-year-old "fuck you dad, I'm going to make my room
extra untidy just to piss you off!" mentality. His brain, even under the best circumstances, was too smooth to move past that stage of emotional development, and that was before he started blitzing it with alcohol and solvents.
People forget what the literal meaning of "retarded" actually is. It means "delayed" or "backwards". Retards get stuck at a pre-adult phase of emotional and/or intellectual development. Cobes got stuck at 14. Cyrax got stuck at about 11. Dan Larson got stuck at about 6. All those people are genetic catastrophes whose brains just didn't develop fully, and never will. You can't explain adult concepts to them because you are interacting with the brain of a child.
