With an entry titled, “Snowbound”, GRRM hints that he’s on a writing roll with A Dance with Dragons, writing what seems to be a Jon Snow-centered chapter. He mentions that “Pat” has died a brief but gruesome death, a reference to a character named after blog reviewer, Patrick St-Denis, who won the opportunity to have a character named after him (and promptly die a horrible death) over a football wager.
It looks like some blood will be spilled, late in Jon Snow’s ADwD chapters.
