We all love this quote from Ser Barry, and people have dissected the issue of whether Daenerys will turn out to be mad or great ad infinitum. But I believe this quote could be a huge misdirect. It leads us to assume that we should be watching out for potential signs of madness in Daenerys, but there's someone else we're forgetting about. If R+L=J, then this quote applies to Jon as much as it does Daenerys. Most people assume that he's the star of the show in the series because of how well his story fits the hero's journey/monomyth patterns of storytelling, but I don't think we should take it for granted that he's headed for the 'greatness' side of the coin. We know Jon has morals, we know he's an upstanding citizen and a good leader. We know he loves his family and values his honour. We know he's sacrificed and bled for the Watch. But we also know where that got him. He did everything he could for them, got them through the Battle at the Wall until Stannis got there, joined the Wildlings, and served as Lord Commander, but they killed him for it. To add to this, it's highly plausible that Jon will soon find out (perhaps during the period between death and inevitable resurrection) his true parentage, which will grant him the knowledge that his father, the man he trusted above anyone else, had lied to him his entire life. It's also reasonable to suggest that if Jon is resurrected through the magic of R'hllor, he will come back with a piece of himself missing, emotionally speaking, the same way Beric Dondarrion always does. He won't be the same. So with all of this in mind...does anyone else wonder whether we could be seeing a huge bait-and-switch in the near future, with Daenerys staying sane and Jon going mental? I'm a big Jon fan so it would disappoint me, but it would be very interesting. Regardless, I think we should pay close attention to that Ser Barry quote, since it seems to heavily imply that our two central Targaryens are not going to wind up on the same side of the coin. EDIT: A lot of people are saying the quote mostly refers to Targs who are the product of incest. That's probably true to some extent, but you'd have to think that with so much incest going back hundreds of years in the Targ line, marrying outside the family once in a while wouldn't completely make people immune.
