The full text of Jon Snow's letter to Sansa suggests there'll be some tension in the North
Note: This post contains plot points of the final episode of season seven.
Lest we forget, Sansa Stark is the lady of Winterfell. Game Of Thrones hasn’t been shy in reminding us of that. After Sansa and Arya’s dissension dissipated with the slaughter of that nefarious Littlefinger, Arya reminded her sister of that very fact as they overlooked the grounds. The North is Sansa’s realm. Earlier in the series, standing in that very same spot, Jon Snow offered her that same assurance before he rode off to meet Daenerys.
Here’s a reminder:
The thing is, while Sansa has been ferreting out rats in Winterfell, Jon has been bending the knee to the Dragon Queen (and a whole lot more) while recruiting Cersei’s forces to help battle the army of the dead. Those are some pretty big decisions to make without once consulting your primary colleague. As such, Sansa’s bound to be a touch, well, surprised, when she gets the below note.
