If the Vegas situation was so great why did they leave? They each had their own house, Kody didn't have to drive all over town, the kids could play in the cul de sac, no one was persecuting them, what was the reason? Something new to do on TV? Seems dumb now.
Asking them all to live in the giant house is totally unfair seeing as how they are going to need something to pass on to their kids. The only type of person who would want to buy a giant house like Kody wants to build is some creepy, cult leader.
Once the show finishes, which wives will stick around? Robyn and Christine or just Christine? She seems the most sucked in by Kody's limp charisma.
