The best thing I can say about the final result was that at least Jenna admitted it was hard to see herself as others see her and it helped her grow. I hope she was being honest, but I doubt it very much.
The thing that bugs me is Jeff mentioning Heidi's IQ. I don't see where that makes any difference to her intelligence. Some of the the smartest people I know couldn't find their way out of a paper bag. Give me common sense any day. Heidi obviously doesn't have any.
