The kid that works for nucky that found him after he was robbed could that be james darmody son
See several posts above.
I was thinking same thing but how would he ever know that Nucky killed his Dad? Because his Dad and mom were dead and grandmother went to the looney bin.
I can think of three ways. 1, Richard Harrow might have told the full story to his sister or girlfriend who raised Tommy.
2 Tommy knows who his father was and Nucky spills the beans about the murder in a fit of self loathing.
Or 3, Gillian gets out, seduces the kid (to continue her incest extravaganza)and tells him she didn't kill Jimmy, Nucky did.
