For those who dont know Ron is an fucking awesome interviewer, he gets deep without going dime store psychiatrist like Wiggy does.
I doubt Ron will shy away from asking about his relationship with Stern and the suicide attempt. I seriously doubt Artie will say anything controversial though...he'll probably just say that he put them in a bad position and that Howard gave him the chance of a lifetime and that he'll be forever grateful. And from Artie's perspective, that's pretty much true. Its up to the rest of us to hold Wiggy accountable for his exploitation of people who are disabled or drug-addled.
