You guys. Look at this thing. LOOK AT IT.
Via Making Game of Thrones:
Transcript: “I, Lady Sansa Stark of Winterfell, do here present my faithful servant, Lady Brienne of Tarth. Please afford her very courtesy and the respect due her as my envoy, who speaks with my voice. Dear Uncle, I was a little girl the last time you saw me. I am not a little girl anymore. The Boltons who murdered my brother and my mother—your sister—now walk their halls, eat at their table, and sleep in their beds. I call upon the bonds of Family, Honour, Duty, and beseech you to lead every man you have north to help us avenge our family and take back the hoe our enemies have stolen. Lady Sansa Stark of Winterfell.”
There is one thing she missed: Catelyn was Edmure’s sister. Uncle Brynden is the younger brother of Sansa’s grandfather, Lord Hoster Tully, who died in Season 3. Catelyn was his niece.
Also, the Tully motto is, in this order: Family, Duty, Honour.
