I believe House Tarly is the third strongest house in the Reach, after the Tyrells and Redwynes. Randyll did fought for the Targaryens during Robert's Rebellion and successfully defeated some of Robert's forces.
I don't think I see an ice dragon, its probably the Night's King mount when he invades Westeros, if he invades Westeros once he defeated the Night's Watch. Don't even need to dig tunnels beneath the Wall.
That is the most satisfying death I have seen since the Purple Wedding. An unfortunate end for the Boltons. Hope we can see the same with the Targaryen girl and her annoying dragons.
Explain why so many cool Nords from History's Vikings died, I will blame it on GRRM, he must have been the secret writer of Vikings. lol
Who would be Thorin Oakenshield? Tormund Giantsbane or Jon Snow? or perhaps Wun Wun the Giant?
You jest? Sandor/Gregor/the Boltons and some other unseen villainous characters from the books are my favourite. I guess I'm probably one of the few who like the gore part of GOT, over the nudity and other less important stuff.
