Just watched this and all I can say is...what a strange show. It was obvious that Emily was faking the whole thing and so was John.
Emily quit for the weirdest reason, I think? I'm still not sure why she walked. So, yeah, she was a fake. John seemed to want his 15 mins of fame.
But what really made it sad was I got the feeling Mitch was really hurt and John's parents were duped. So TLC planted two phonies in the show for entertainment value I guess but I didn't find it entertaining. It was just weird and disturbing.
