I cannot even begin to imagine the excruciating pain that Kim must have felt. To lose your little boy is bad enough, but knowing that you killed him? That is truly life-ending pain. I couldn't have gone on, I don't know how she did.
Ethan has the mentality of a 13 year-old boy, and the sex appeal of a turnip. There is no gym that would allow him to play on the equipment like that. He was disrespectful, and I'm surprised he wasn't hurt.
Also, please don't ever make me listen to Moriah sing again.
Ethan and Olivia were flat out wrong to go over to the house with the parents gone. The right way to earn trust is to ask permission, not sneak over the minute they leave. It's a stupid rule, but it's their house.
Olivia was right when she said that their theological differences are never going to change, so it's going to be very difficult to resolve their problems. All Kim and Barry can do is raise the kids with respect and integrity, and teach them their beliefs. Then have trust in the kids to make responsible decisions as they get older. It's impossible to keep them sheltered forever, all they can do is give them a solid foundation, then let them go. As adults some may continue to live like the parents do, and some may not. That's how it goes. Forcing it like Kim and Barry only causes resentment and rebellion. It's not Olivia that's changing the older kids, they're just growing up.
I just wanted to add that I hate it when they say "The Gays".
