Spoilers for Game of Thrones, season 7 below.
Assuming Bran Stark isn't the f*$king Night King, his meeting with Samwell Tarly in the grand finale of Game of Thrones season seven could mean the birth of the series' most powerful duo. Apologies to these guys:
In a viral theory posted to Reddit's r/GameOfThrones forum, a greenseer named Kinboy spells out the prophecy that "Bran is now Samwell's master codex."
Drumroll for the new nickname...
"He is Encylopedia BritBrannica."
To have the most curious character meet and partner with the most omniscient character is to create the Internet in Westeros. Sam won't have to dig through books and tomes anymore. He can simply BRoogle the answer and away we go.
They are instantly the most powerful people in Westeros.
