I recently just re read the Eye of the World and i noticed something odd. I didn't notice it the first time i read it because i didn't know who jain was. But Ba'alzamon who in one of the last chapters says "whom i painted like a fool and sent to the ogier thinking he was rid of me." This raises the question in my mind whether Jain is a darkfriend or not?
If Jain is a darkfriend, or an "ex-darkfriend" we must consider the possibility that Noal his cousin is one as well. Not because being a darkfriend is a hereditory trait, merely because it may well be jain himself.
Just wanted to throw this out there.
