The mothers have clearly lost the plot. This is a TV show ladies and these women don't live anywhere near you. Relax, your boys are thinking with their little heads and nothing will come of this. And boys, move out.
Next week we will see more action. JoJo will walk away with his mom. There isn't a girl on the face of the planet that would consider marrying into that family. Mother in law from hell has taken on a new meaning.
Erica will queer the deal with both Michael and his mom and he will "choose" the med student. He would probablly rather walk away but since Mrs B chose that role he will be mandated by production to choose.
Rob will choose Camilla, again, a production must no matter what.
This show will not see another season.
