Well, this is totally disappointing. A little googling (very little googling) and it appears that nobody on this show is who they present themselves to be. Not one of them is fresh out of the community. All of them, with the exception of the model, have been married or are currently married. Jeremiah has been divorced and has a couple of kids. Allegedly he was abusive to his ex-wife. Rebecca and Abe are married and have child (her second marriage). Sabrina has been married and divorced. The model has been away from the community for awhile, being a bartender. And Sabrina has been on a reality show prior to this.
How much of this was known to the producers? I'm thinking ALL of it since I agree with the above posters that that is probably not Abe's mother but an actress. Certainly when the others have their "back home" moments, it must be very apparent to the production crew and producer that these folks haven't been living Amish for a very long time.
I feel completely played. Shame, shame, shame on TLC.
