The problem is, John, Marty, Brody and Natalie are four of the characters I hate most, along with Gex and Nora. I'd rather see John and Marty hook back up - they deserve each other. I liked Natalie when she wasn't with John but once they put her with him, I started hating her more and more and now that she's lying about being with Brody, or omitting that they slept together - well - it would serve her right if the baby really was Brody's.
The thought of John procreating makes me sick, given what he did to Todd and how his criminal actions were covered up. He deserves karma - to have his child stolen and sold on the black market and have everyone conspire to keep him from that child - let the child disappear and leave John to mourn, the way he left Todd.
