Just people throwing shit at a wall. To take just their first prediction of Sansa going north because she did in the show. Sansa's arc has long been recognised as pawn to player, the game is the Iron Throne and the board is in the south. Set up are Sansa's pawns.
- Jaime for who Sansa is his last chance of honour.
- Brienne who has declared a vow to Sansa's mother to keep her safe.
- The newly devout Lancel, set to renounce every material item and become the Faith's highest recruit, who treated Sansa horribly only for Sansa to show him unwavering kindness. Has the info scoop on Sansa's enemy to be Cersei.
- Sandor the reborn, his anger apparently quenched by the Seven just as Sansa prayed for, who she can't stop from invading her thoughts.
- Tyrion, soon to be dragon rider, susceptible to the manipulations of young beautiful girls. GRRM locked them in marriage, which won't just disappear.
Cersei for her end game enemy, the Dance of Dragons to provide her the chaos in which to play as TWOT5Ks was to Littlefinger, and you got yourself a character arc and a story.
In the north there is Jon for whom Sansa has given about two lines of thought in the whole series, and fuck all else. The north is decidedly where not the game of thrones is played.
