Rob's issue is the same as it always was - he want's to be the father to a boy. A boy who he can bring up as a proper man. His mother is the perfect mother, an the example of how a woman should behave, Helen must learn to be the same. There's some shit going on with his father too, that I'm not quite sue of. Except to say he's almost definitely a bastard as well.
Actually, Rob n his mom sound almost incestuous. But that would be a step to for even for SOC.
I think it is building to a climax now [note: a climax, not the climax], but it'll still be another month or so.
