I don't mind reading some spoilers but I know some or most probably do. Put them all ITT so we can avoid anyone accidentally reading something they don't want to in the show threads. (And so people can continue to post in those threads without fear of doing so)
so one of Dany's dragons (Viserion) is killed and a white walker or the nights king turns it into an ice dragon? guess that is what the picture is making the rounds
But only after Tyrion prearranges the coitus and her council discusses the matter in full, of course.
Spoilers! spoilers!. I love the spoilers so, I can wait patiently to see that happening. But, secretly hate it, sometimes, it ruins the fun.
Odds are that Kit Harrington is just fucking around and carrying a big dragon head prop for the hell of it and now D&D are enjoying people going crazy.
