For Arya, they brought her to the logical conclusion where she realizes that she's sick and tired of being around death. I honestly think they're even going to have her go back to Gendry. She doesn't have to be a "lady" but she doesn't want to The Hound either.

And is much as a drip Jon can be, they've been remarkably consistent with his characterization. Everything more a less feels logical, as self-serious as he is.

I'm hoping that the show ends with him going back to the true North. He takes out Dany, (probably after she threatens to destroy Winterfell; she's not going to let Sansa's betrayal stand), melts down the Iron Throne, sets up a representative government. Then he goes beyond the wall to live with the Free Folk and Ghost, where he's neither a Stark or Targaryen.
