As much as I'd hate to see another series where the women share but the men don't *cough cough, Jordan cough*, I think the third head needs to be female, due to Dany's barrenness. I don't see Jon disgracing himself again, especially after realising that Ned didn't father a ******* after all. He needs a wife who can give him Targaryn children.
On the R+L=J note, at the start of AGOT Ned says he has 'lived a lie for fourteen years'. Could this Wylla we hear of be some random woman? We hear about a baby switch in AFFC, why not have one before that? Maybe Wylla's real baby died. Come to think of it, maybe Ellia's baby was switched... Somebody stop me. If I keep on at this rate, Tyrion will be a Stark and Ned will be a Tully... More incest!! Oh god, someone stop me...
i havent read Jordan, but the fact is that historically (ever since humans settled down, before that we where still equals, perhaps men where even lesser then woman because berries and roots where the main food supply then, the hunting did not bring that much food to the table) men came before women, it was normal for a man to have several wives, it is even so in the bible, Abraham and the lot had more then one wife, there where plenty of harems in the east and so on, even know in places in Africa it is considered normal for a man to have a multiple wives, the eskimo's on the other hand share their wives with strangers, as a means of survival (new blood) On the other hand women where for most forbidden to sleep with anyone but their husbands, in the middle-east, you can get stoned for just looking at a man the wrong way.
So in that way it is normal, perhaps you should not read books in a modern day western viewpoint. After all, it is not even (or at least not much more then that) a full centure ago that women have less rights then men. Even now it is said that men are considered more (jobs go to men more easily and all that), even so i have to say, that while women always whine that even know in western europe/and america they still dont have more rights, that they dont have the same duties as well, i mean (at least in my county it is so) for example men have to work longer before they get their pension, while women live longer, now how in the world is that fair, i have not once seen them protesting that they want to work as long as the men must work. Also it does cost the companies a lot of money every time a woman must take childhood leave. If they want equal rights, they must also get equal duties.
Dont get me wrong, i am all for the equality of women, but then it must truly mean equality, to often women are positively discriminated.
Hell i would love to be a house man, and that my wife will go to work have a career, i'll take care of the house and the children, that would be graet for me personally.
