also, is the R+L= J twist not the coolest ever? the TV people will go nuts when that is eventually revealed.
I actually disagree with this and feel it's one of the most disappointing parts of the television show.
As of right now, I think the show has really done little service to Jon's parentage. We didn't get Ned's visions. Admittedly I've only watched Season 2 once, but I can't remember any particular references to R+L=J. House of the Undying seemed to diverge a good bit from the book. And I doubt we'll see a flashback to the Tower of Joy.
I guess that Jojen and Meera may be able to provide some information this coming season, but it's never struck me as an important issue on the TV show. Obviously (assuming the show lasts long enough) it will come out, but I don't see how it will resonate much with the audience when we haven't met R or L.
Still dig the series. Just think they'd need to do significant legwork to make the reveal matter to the TV audience.
