Re: T. Ray don't know nothing.
You must expect that characters in fiction will speak in non-standard dialects.
"He doesn't know anything" is standard. "He don't know nothing" is exactly what you would expect from a character who doesn't know proper grammar or who doesn't care about social conventions and using "good" English.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
