I was wondering what do you think about the possibility that the "giant in armor made of stone" is Littlefinger? It seems like he has a connection to Ned, Sansa (like Sandor and Jaime has with either Ned, Sansa or Arya) - betraying Ned and trying to manipulate Sansa. And it fits to GOHH's prophecy "And later I dreamt that maid again, slaying a savage giant in a castle built of snow." What do you think?
He saw Sansa crying herself to sleep at night, and he saw Arya watching in silence and holding her secrets hard in her heart. There were shadows all around them. One shadow was dark as ash, with the terrible face of a hound. Another was armored like the sun, golden and beautiful. Over them both loomed a giant in armor made of stone, but when he opened his visor, there was nothing inside but darkness and thick black blood. –AGOT, Bran III
The three shadows in Bran’s dream, looming over Sansa and Arya, are certainly Sandor, Jaime, and Gregor. It was uncertain who the third was until ASOS/AFFC/ADWD, but since Ser Robert Strong has no head and his blood has turned black, it’s pretty much a given. And Gregor is certainly connected to Arya (as she was his prisoner and his men are on her list) and Sansa (via Sandor, and via the fact that Cersei will use Robert Strong to destroy her enemies). You can see my further analysis of this subject in this post and in this tag.
Many do theorize that the “savage giant” from the Ghost of High Heart’s prophecy could be Littlefinger, due to the fact that the original House Baelish sigil is the head of the Titan of Braavos. Nevertheless, if that prophecy has not already been fulfilled by Sansa destroying Sweetrobin’s “giant” doll in her snow castle Winterfell, I still believe it’s Gregor. Petyr Baelish is not particularly savage (even when he personally killed Lysa it was in entirely cold blood); and the fact that neither the Ghost’s prophecy nor Bran’s dream has any mention of the giant having fiery eyes, which the Titan and the Baelish sigil have, leads me to put Littlefinger as a very low probability.
I also theorize the “castle built of snow” may be Harrenhal. I am sure Sansa will get to Winterfell eventually, probably in ADOS or by the end of TWOW, but I think she may have some detours for most if not all of TWOW; plus, she has connections to Harrenhal through her Whent grandmother, through Petyr’s lordship, and through potential Arya parallels, and Harrenhal has seen the fiery death of Strongs before. Winterfell is still a very strong snow castle option of course, but I doubt Littlefinger will ever make it to Winterfell, and it’s a long long way for Robert Strong to travel even if he is a tireless zombie on a mission. (A marvelous fic concept, though!)
Anyway, you can believe what you like, and you do have fellow-minded others if you want support, but
you did ask me, and these are my theories.
:) And let’s be real, we can’t know for sure until the books get to the point where Littlefinger and/or Gregor dies (again, in his case), and if Sansa is involved and where those deaths happen. So we’re just going to have to wait and see…
