The sad things is, TPTB ruined Marty the moment they put her with John. They've turned her into a hypocritical, unprofessional creature who is enabling her violent, would-be murderer son. I'm surprised they made Nat pregnant so soon but I bet they're setting up a baby-switch - Nat will loose her baby and end up stealing Jessica's. The thought of John procreating is disgusting and nauseating! The only way I want that SOB procreating is if he gets karma for what he did to Todd and someone steals the child and lets him believe the child is dead so he can mourn the way he was letting Todd mourn Sam.
I really hope this kid is Brody's!
