there is the whole thing about genetic sexual attraction . don;t know a huge amount about it
it was a bizarre programme
especially stephanie and her half brother. he gave up everything, and she decides she is not ready.. at the end of the day, not only were they being unfaithful, they were doing it with a half sibling, someone also related to their children then..
too complicated, too difficult
thought it said earlier in teh programme that danielle was now infertile. so she has no chance of having more children and has given up her own daughter to be with her half brother
not much of a trade off, imo
