Game Of Thrones Season 7: 10 Big Things We Still Haven't Seen
9. Where Arya Is
In contrast to Sam, Arya has been in both of the trailers so far, and yet we've been given just as little clue as to what her storyline will actually involve.
All of the images of Arya so far have shown her alone, in an unidentified location, mostly looking very cold.
Given her stated intention was to go home, it's a fair assumption that she's in the North and on her way to Winterfell. At the same time, with winter arriving in Westeros, those snowy locales could well be the Riverlands too, so it's not entirely clear where she is or what she's up to.
I think it's a safe bet that Arya will end up back at Winterfell eventually, and perhaps after reuniting with at least one familiar face (Nymeria is surely coming back this year, right?), but the trailers and images aren't giving anything away on that front.
