I thought it might be an interesting possibility if Cadsuane were to teach the Asha'man something to do with their going insane. Specifically the question of how Rand is able to stay sane while others are going to go insane soon (we know this due to info 'leaked' on PoD). So what is the only difference between Rand and the other Channeling men? . . . Rand has been bonded (remember Min said they would not like it, what would be more distasteful to men who can channel?) And Cadsuane is green after all, said she was looking for a new warder, etc. A bond provides many things to it's recipient, not the least of which might be a dispersion of the madness from the taint (I think there was something mentioned about that when there was a discussion surrounding the use of a 'control collar' for men who can channel, which would be similar to a bond). As to the foretelling, that is not specific as to who is 'rent in fire and blood' just where, there are a heck of a lot of ! Asha'man there for forty or fifty (I forget the exact numbers) sisters to take out.
