Jon and Arya reunion
Jon flies on Dany's dragon to the North, but stuck at some kingdom slightly south of Winterfell while he is healing from some random battle he had with Wight walkers
Arya rides to said kingdom and kills a ton of guards because they don't believe her when she says she is a stark
Jon sees her and run/hugs her
Makes fun of her for still having needle
Arya cries and laughs, punching him for not coming home sooner
