This is the classic cliff hanger. Pick a topic that is controversial, add a dose of dissention, string it out and surprise everyone. It keeps viewers coming back for more. It's a tactic to build viewership and ratings.
Apparently, someone there is very familiar with this issue and the heated passions around it and they are using it to build their ratings. That's OK with me because there are millions of viewers and they seem (from the trailer I've seen) more than willing to put the truthful information out there. No matter which way it goes, it's good for intactivism. I think we can expect this to be stretched out over several episodes to milk it for all it's worth.
One possible scenario I see coming is for there to be a heated argument between mother and father with the mother finally coming around but not totally convinced. But in the end, the baby comes home with all his parts intact. Then, Bree being the compulsive type and being the perfect wife and homemaker and wanting for cleanliness, etc., etc., conspires to get the baby alone and have the circumcision done. From that point, it gets a little bit muddy. If she succeeds, there will be a massive argument and if she doesn't succeed and gets caught, there's going to be a massive argument. There will be alienation and retribution. Somehow in the end, everyone will work it out.
Another possible scenario is that the baby won't be circumcised but will "have to be circumcised" later and you all know the story from that point.
I've watched maybe 2 or 3 episodes of DH but you can be sure I'll be watching to see how they handle this. That's just what they want!
