What I meant by that is that most married couples are not 'destine' to be together. Birgitte and Gaidal could be an exception since they are hero's of the horn and thus a special case. All I was saying is that each turning of the wheel is a little different and every person is not destine to do the same thing or be with the same person again and again. An example of this is we know during the AoL that about half the channelers turned to the shadow(according to the big white book) . In this age only about 20% of the Aes Sedia are BA, which means some channelers who's souls fought for the shadow last time chose the light this time.
