Um..... Jimmy and his "Mom"?
Is that actually his Mom or is it more like she adopted him? cause she seemed quite young.
I just started watching this on Amazon and i'm barely on episode 2. I thought that was his mistress or something and when he called her "Ma" I assumed that was just slang for babe, baby, or honey but then she started talking about his "father"
Also, how were none of the other showgirls thrown off by that? I know it's set in the early 1900's but I'm sure, even then, incest was frowned upon.
