I liked Sean's family. I think they all had to be a bit stone-faced at first so as not to give away the joke that was being played about Sean living at home, and they all knew Emily was in for a shock when she saw that mess. As a vegan, I could have done without the sight of that dead armadillo on a platter, though, but that's neigher here nor there except it shows they have a sense of humor.
Emily does have to "follow the money." She has no resume, no job plans, just wants to have kids kids and more kids (if you believe that), so somebody has to finance that. The Hendricks will pay for Ricki but not a whole slew of more children.
