Frankly, my dear, I don't give a damn.
I wondered so many times why not a single one of the journalists tried to reply with this - the quotation is from the film only, not the original text from the novel; it would have been both tongue-in-cheek and a meta opener for the GoT/ASoIaF conundrum we are facing now : what is the journey (the path) if not to be mirrored by the end?
I don't think Daenerys will be the mad queen but I do think she won't escape the legacy of her truly mentally damaged father and brother and while not crazy she will experience the bias of those around her : bias through superstition, fatalism, distrust, fear and perhaps most dangerous of all - being foreign to Westeros .
As for the narrative, it may very well be that Dany's coin of "madness" and greatness will continue to spin in perpetuity, never landing on the ground, becoming part of the legend and mythology just like her dragons.
Jon seems to be poised to leave Westeros to the Westerosi, curtail the supernatural threat(s), following his resurrection turning out to be a very sombre figure trying to do the best for the common good as hard as this sounds. Heartbroken.
At this point I just want to send a shout-out to my Bloodraven who knows Targaryen glory is coming to an end.
