I wish C&F had come down harder on "it is never okay to punish a child for the sins of their parent." I sense that LW mostly gets that, but I think it needed stating more firmly for the inevitable moment when Mom learns LW is still friends with James. LW needs to be prepared to firmly state, "Mom, what Dad did is not James's fault, and it's not okay for you to call him names."

LW2...yeah, I agree about the DNA test, because this needs to be nipped in the bud well before LW's kids are old enough to understand.
