Rusty Dennis: First you told me he was gonna be retarded, then you told me he was gonna be blind and deaf. If I'd dug his grave every time one of you geniuses told me he was gonna die, I'd be eating fuckin' chop suey in China by now.
Rocky Dennis: Don't worry, Mr. Simms. I look weird, but otherwise I'm real normal. Everything'll be cool.
Rocky Dennis: What's his problem, Ma?
Rusty Dennis: Nothing. He's just another asshole. You let that negative dreck in and it'll put ya away. You can be a chickenshit and die or be a mensch and keep makin' yourself well.
Gar: Rocky, your mom sometimes does the wrong things, but for the right reasons.
Rocky Dennis: Mom. Do I look like a freak to you?
Rusty Dennis: No.
Rocky Dennis: You know, your always been big on telling me when my face doesn't matter, but, it does. Doesn't it? You think that I can't even get a girl to like me unless you pay for her.
Rusty Dennis: That's not true.
Rocky Dennis: Bullshit.
Rusty Dennis: Bullshit yourself. You know lots of young guys got problems getting girls. Well, what if I was your dad and I did the same thing?
Rocky Dennis: I'd hate that too.
Answer: His official cause of death was listed as "sudden arrhythmic death syndrome," which is basically just when someone dies unexpectedly, usually during sleep. It's widely believed that it was caused by his disorder, as his disorder often causes early death, but to my knowledge it was never definitively proven.
