Yeah, I didn't think that was possible either.
Anybody who has thumbed through Dances with Dragons knows that Martin has completely lost the plot of his epic masterpiece and is now basically writing his own fan fic.
It turns out that Martin lost the plot a long time ago.
Here is a link to Martin's original cover letter and outline from 1993.
The last paragraph on the third page is blacked out so "the big secret" of Jon Snow is still in play.
"Arya and her half brother Jon fall in love, and "their passion will continue to torment Jon and Arya throughout the trilogy," which is a serious deviation in that the thought of people actually hesitating to commit incest in Westeros is shocking." (*Stolen from Cracked.*)
