We May Be Able to Confirm This Theory About Sam Tarly
In Season 6, a theory emerged as ambiguous and convoluted as the fight for the Iron Throne.
When Sam first walked into the Citadel at the end of the season, we were faced with the image of the giant spinning astrolabe, speculated to be the same one as in the show's opening credits.
This scene prompted a tornado of theories, the most talked about being that Sam is the one telling the story of Game of Thrones.
Now that Season 7 is in full swing and Sam has been in Oldtown for some time, we have another clue that actually makes this theory pretty convincing.
In episode 2, Archmaester Marwyn discussed with Sam the importance of recording history in books, admitting that "a little style" is necessary to make it a bit more interesting.
Sam questions the Archmaester's title, A Chronicle of the Wars Following the Death of King Robert I. Samwell suggests something "a little more poetic."
Could it be that Archmaester Marwyn doesn't get to finish the book? Or that Sam takes over more than just the title?
Either way, it's beginning to seem exceedingly likely that Sam is the narrator of the entire series thus far. And, truly, what better character to recount the series of events than an honest, hardworking, truly good guy, one of the only ones in the show?
George R. R. Martin has even compared himself to Sam on multiple occasions, stating that if he were to be any character on the show, it would be Sam.
Who knows, maybe Sam will finish writing the series before GRRM.
