I can see where you are coming from, not sure if I'm in 100% agreement though. I don't mind them either, but I have stopped reading other fantasy because, after awhile, I felt as if I was reading the exact same story over again.
I'm fine with Jon/Dany happening, as long as Martin writes it well and I have no doubt that he could. By big hangup over it as that I still don't see the foreshadowing that I've been told is there. The flower on the wall giving off a sweet smell doesn't seem like enough for me. But, perhaps its my reading skills at play here.
Waiting for PatrickStormborn or WK to come out and correct me on the above here. /smile.png' class='bbc_emoticon' alt=':)' />
The blue flower is obviously a rose Kits.
Symbolically: In some cultures, blue roses are traditionally associated with royal blood, and thus the blue rose can also denote regal majesty and splendor. In Chinese folklore, the blue rose signifies hope against unattainable love.
Furthermore, this is the only vision that has an olfactory detail: the rose fills the air with sweetness.
Then of course there is the wording:
Her silver was trotting through the grass, to a darkling stream beneath a sea of stars. A corpsestood at the prow of a ship, eyes bright in his dead face, grey lips smiling sadly. A blue flower grew from a chink in a wall of ice, and filled the air with sweetness. . . . mother of dragons, bride of fire . . .
In my opinion, it seems to symbolise her three mounts: one to bed (obviously Drogo, since Martin disagrees with my personal thoughts on how this is just as likely to be the mount she dreads), and the next two.
But Patrick has a better grasp on this than I.
