I dont know, but at least he had the common sense ot get away from his crazy parents! But they never compared him to George so he must not have been doing so well.
When you say if he stuck around, what do you mean? Did they say he left for some specific reason or do you mean because he was never shown he must not have stuck around?
I guess I would see him as a Lloyd Braun type that George would always be coming in second to. But as Sinatra said then there should have been comparisons to George. I can only assume he was not that great of a son since he was never mentioned.
